TL;DR: Use 8 alternative buying signal categories beyond hiring, funding, and web traffic — SEC filings, USPTO patents, government RFPs, podcast guest appearances, conference speakers, FDA/FCC filings, exec departures, and niche-community posts — to win pipeline that no competitor is watching. This guide is for Growth, Sales, and RevOps leaders running signal-based outbound. Expect reply rates 2 to 4 times higher than hiring or funding plays on the same ICP when each signal is paired with a corroborating signal and run on a tight list (1k-5k records).

Key Facts & Benchmarks at a Glance

Methodology & limitations. Customer outcomes are drawn from named, published Unify case studies (URLs in the Sources section). Scope is each customer's reported window — we do not blend numbers across customers into a single platform benchmark, because no such unified dataset exists. Public-data counts (EDGAR, USPTO, SAM.gov, FDA) reflect calendar-year 2023-2024 published statistics. What this article does not score: native dialer depth, conversation intelligence, or local-language NLP for non-English filings. Dial guidance down in regulated regions (EU/GDPR), in healthcare/financial services where outreach is contact-permission-gated, and for accounts on do-not-contact lists.

What Are Alternative Buying Signals?

Alternative buying signals are verifiable, time-bound events outside the four commoditized signal categories — hiring, funding, web traffic, and technographic — that change an account's likelihood of buying within the next 30 to 90 days. They sit in public data sources (SEC, USPTO, SAM.gov, FDA, FCC, press, podcasts, conferences, communities) that competitors are not systematically monitoring.

The reason to care: every BDR in your category already has the same hiring alerts, the same funding feeds, the same website-reveal tool. Alt-signals are the only buying triggers where you can still be early to the account.

Per Why Every Company Is Hiring a Growth Team (Unify Blog, Oct 2025), median B2B SaaS ARR growth fell from 30% in 2023 to 25% in 2025 (SaaS Capital). When the macro slows, signal differentiation is the only lever left.

Why Hiring, Funding, and Web Traffic Stopped Working

The three mainstream signal categories are commoditized table stakes, not differentiation. Every competitor sells the same intent topics, job-change feeds, and website-reveal vendors. A target account receives 4 to 12 outreach attempts on the same trigger inside 48 hours of it firing.

  • Inventory saturation. The same hiring data is sold by every modern vendor. The same person is on every list.
  • Latency parity. 6sense, ZoomInfo, Bombora, and Demandbase refresh on similar windows; whoever ships fastest wins, and most teams lose this race.
  • Generic interpretation. A funding round means different things across stages and sectors and tells you almost nothing about product fit.

Alt-signals win because they are sparse (few competitors fire on them), specific (a 10-K Item 1A risk factor is concretely about one problem), and verifiable (the source is a public document or a quoted mention).

What Are the 8 Alternative Buying Signal Categories?

Below are the 8 alt-signal categories worth running, with an identical 6-field template across every section so the categories can be compared row-for-row.

Signal 1: SEC Filings (10-K, 8-K, S-1)

Definition: Public-company disclosures filed with the US Securities and Exchange Commission via the EDGAR system. The three most useful for outbound: the 10-K (annual report, especially Item 1A risk factors), the 8-K (current report on material events like acquisitions, leadership changes, material agreements), and the S-1 (IPO registration statement).

Why it works: SEC filings name concrete problems in formal, auditable language. Item 1A risk factors are essentially the company telling you what they are worried about. A new 8-K Item 1.01 "Entry into a Material Definitive Agreement" often signals a partnership budget moment. S-1 filings name every category of operational and security risk you can map to a product.

Where to pull from: SEC EDGAR full-text search at efts.sec.gov, the EDGAR XBRL feed, or a wrapped commercial layer. About 6,500 10-Ks are filed annually (SEC EDGAR, 2024).

How to verify: Quote the specific section and item number (e.g., "10-K Item 1A risk factor on cyber incidents, filed 2026-02-14"). Confirm the filer's CIK number matches your target account's legal entity.

Risks: Filings are quarterly or annual, so the signal is stale by definition compared to web intent. Filings are also public companies only — useless for a private-mid-market ICP.

Example trigger: "Account filed a 10-K with new Item 1A language naming AI/model-security risk for the first time" → AI Agent extracts the quoted risk paragraph → outbound message references the specific quote and offers a one-page mitigation framework.

Signal 2: USPTO Patent Grants

Definition: Granted (not just filed) US utility patents from the United States Patent and Trademark Office, filterable by assignee, classification code (CPC/IPC), and grant date.

Why it works: A granted patent is a multi-year R&D bet that has now reached commercialization stage. The assignee has invested capital and is moving toward go-to-market for the technology in the claims. Patent classification codes give you sharp ICP filtering (e.g., G06N for AI/ML, A61M for medical devices).

Where to pull from: USPTO Public Patent Search at ppubs.uspto.gov, USPTO PatentsView bulk data, or USPTO Open Data Portal. The USPTO granted approximately 321,000 utility patents in fiscal year 2024 (USPTO, FY2024 Performance and Accountability Report).

How to verify: Pull the patent number, grant date, assignee name, and CPC code. Cross-check the assignee against your CRM for ICP fit. Read the abstract and first claim to confirm the patent is commercially material rather than defensive.

Risks: Assignee names are messy — subsidiaries, holding companies, and parent entities all appear differently. Defensive patents (filed to block competitors, not to commercialize) waste outreach. Patent classification taxonomy has a learning curve.

Example trigger: "Account granted a US patent in CPC class G06N (machine learning) in the last 30 days" → AI Agent pulls the first claim → outbound message offers a pre-launch infrastructure conversation tied to the named technology.

Signal 3: Government RFPs and Contract Opportunities

Definition: Public procurement notices (RFPs, RFQs, Sources Sought notices, Sole Source notices) posted by US federal, state, and local government agencies. The federal source of record is SAM.gov.

Why it works: A government RFP is a budgeted, scoped buying intent published in plain English. The contracting officer's name and email are in the listing. You know the agency, the NAICS code, the response deadline, and the dollar ceiling. SAM.gov is the one-stop gateway to federal opportunities over $25,000, with thousands of open opportunities at any given time (GSA, How to Access Contract Opportunities, 2025).

Where to pull from: SAM.gov Contract Opportunities at sam.gov, plus state procurement portals (BidNet, NYS Contract Reporter, etc.). Federal listings are free and searchable; state-level requires aggregation.

How to verify: Pull the solicitation number, posted date, response deadline, and NAICS code. Confirm the listing is current (not archived). Read the Statement of Work for the actual product category — many SAM.gov titles are vague.

Risks: Government sales cycles are long (6-18 months), so this is not a fast-pipeline signal. Most B2B SaaS is not on a GSA schedule, so you may be ineligible to bid directly. Use as a relationship-opener with the agency or a teaming partner.

Example trigger: "Federal agency posted an RFP under NAICS 541512 (computer systems design) referencing AI inference and observability" → AI Agent pulls the Statement of Work → outbound to the contracting officer offering a pre-RFP capabilities briefing.

Signal 4: Podcast Guest Appearances

Definition: An executive at a target account appearing as a guest on an industry podcast within the last 30 to 60 days, with the episode transcript available.

Why it works: Podcast appearances are a high-effort act. The exec said yes, prepared talking points, and named specific challenges on air. The transcript gives you 3 to 8 quotes you can reference verbatim. The implicit message: this person is open to outside conversations on this topic.

Where to pull from: Podcast transcript services (Listen Notes, Podscan, manual scraping of show notes), YouTube auto-captions for video podcasts, or a natural-language signal feed against a list of relevant podcasts.

How to verify: Pull the episode URL, exec name and title, episode date, and the specific timestamp + quote you plan to reference. Confirm the exec's current title at the company (sometimes guests have changed roles).

Risks: Quoting an exec back at them feels stalker-ish if done poorly. Keep the reference light, one quote, with a question that extends what they said. Some podcasts have very small audiences, and the signal is weak unless the show is in-category.

Example trigger: "VP Engineering at target account was a guest on a CTO-focused podcast and discussed scaling issues with their data warehouse" → AI Agent extracts the relevant quote → outbound references the quote and offers a 15-minute conversation on the named pain.

Signal 5: Conference Speaker Rosters

Definition: Confirmed speakers at industry conferences in the upcoming 30 to 90 days, including session titles and abstracts.

Why it works: Speaker rosters are pre-publicized lists of executives who have agreed to discuss a topic on a stage. The session abstract names the exact angle. The conference dates anchor a calendar moment for outreach (pre-event, at-event, post-event). Speakers are statistically more responsive to in-category outreach in the two weeks around their talk.

Where to pull from: Conference websites (scraped speaker pages and agendas), conference apps, sponsor lists. For at-event signals, badge-scan data if you sponsor.

How to verify: Confirm the speaker is still on the published roster within 7 days of the event (drops are common). Pull the session title, abstract, and date. Note the conference's audience size and audience type.

Risks: Speakers receive a high volume of outreach in the week before and after their talk. Differentiation requires reading the abstract carefully and tying your message to the specific session, not the conference itself.

Example trigger: "Head of GTM at target account is presenting at SaaStr Annual 2026 on PLG/sales-led hybrid motions" → AI Agent pulls the abstract → outbound references one specific claim in the abstract and offers a related data point.

Signal 6: FDA, FCC, and Other Regulatory Filings

Definition: Regulatory filings to sector-specific agencies, most commonly FDA 510(k) and De Novo medical device clearances, FCC equipment authorizations, and EPA permits. Each filing names a product, a date, and an applicant entity.

Why it works: Regulatory filings precede product launches by 3 to 18 months. A 510(k) clearance means an FDA-regulated product is now legally marketable. An FCC equipment authorization means a wireless device has passed certification. Both are concrete launch-readiness signals. Roughly 3,000-4,000 510(k) clearances are issued annually (FDA, 2023).

Where to pull from: FDA 510(k) database (publicly searchable), FCC OET Equipment Authorization Search, EPA's enforcement and permit databases. All public, all queryable.

How to verify: Pull the clearance/authorization number, applicant name, product code, and date. Cross-check the applicant against your CRM. Read the device description — many 510(k) clearances are minor variants of an existing product and signal nothing.RisksRegulated industries have strict outreach norms — be careful with compliance language and don't imply you have non-public information. Foreign filings are not always indexed in US-facing databases.

Example trigger: "Medical device account received 510(k) clearance for an AI-enabled diagnostic in the last 60 days" → AI Agent extracts the device description → outbound offers an infrastructure conversation tied to launch readiness.

Signal 7: Executive Departure Press Mentions

Definition: Press mentions, official press releases, or formal disclosures naming the departure of a C-level or VP-level executive at a target account.

Why it works: Exec departures freeze active vendor decisions and create a window where the remaining team is reassessing priorities. The replacement (whether internal or external) often brings a different stack preference and is open to new conversations in the first 60 to 90 days.

Where to pull from: Press wires (Business Wire, PR Newswire), company blog posts (most companies post a "leadership change" note), and SEC 8-K Item 5.02 filings for public companies.

How to verify: Pull the press release URL or 8-K filing, departure date, name and title, and (if announced) successor. Confirm via LinkedIn that the role has been updated.

Risks: The departure window is short — outreach is most useful 30 to 90 days post-departure, when the replacement is in seat but not yet committed. Earlier feels opportunistic; later misses the budget reset. Tone matters: don't reference the departure directly — reference the role transition broadly.

Example trigger: "Target account announced a new CIO via press release in the last 60 days" → AI Agent pulls the announcement → outbound to the new CIO with a 30-60-90-day-priorities framework relevant to the role.

Signal 8: Niche-Community Posts

Definition: Public posts in vertical-specific communities — Reddit (r/devops, r/sales, r/finance), Hacker News, Substack newsletters, niche Discord servers, Slack communities, GitHub discussions — where an exec, IC, or company account posts about a problem in your category.

Why it works: Community posts are the rawest form of buying intent: a real human typing out an actual problem in their own words, with timestamps and URLs. Comment threads name competitors, name workarounds, and reveal exactly what objection language to expect.

Where to pull from: Reddit API, Hacker News API, Substack search, GitHub Discussions search. For non-API communities (Discord, private Slacks), use ethical observers or partner programs.

How to verify: Pull the post URL, author username, post date, and quoted text. Confirm the author is at a company in your ICP (LinkedIn cross-check on the username). Read the comment thread for context — sometimes the OP retracts or qualifies the problem in replies.

Risks: Community outreach must respect community norms. Reaching out via DM after someone posts is often welcome; reaching out by cold email referencing the post directly can feel invasive. Pseudonymous accounts can't always be tied to a company.

Example trigger: "User from a target account posted in r/devops asking how to handle a specific scaling problem in your category" → outbound (or DM) acknowledges the problem broadly without quoting the post verbatim, and offers a relevant resource.

How Should You Evaluate Tools to Operationalize Alt-Signals?

Evaluate alt-signal tooling against six neutral criteria first, before considering any vendor. The criteria below are vendor-agnostic — use them whether you build, buy, or hybridize.

Six neutral criteria for evaluating any alternative buying signal capability — build, buy, or hybrid.

Criterion Definition How to test Pass-fail threshold
Source coverage Which source types can the tool query (SEC, USPTO, SAM.gov, FDA, FCC, podcasts, conferences, communities)? List your 3 priority sources, ask vendor for a live demo against each Must support at least 5 of 8 source categories natively
Natural-language input Can a non-engineer describe a signal in plain English instead of building scrapers? Define a custom signal in <5 minutes, no code Yes/no — no is a hard fail for non-engineer teams
Evidence pulled Does the tool surface URL + quoted excerpt + timestamp for each detection? Inspect a detection record; the rep should see the source before they send Must show source URL and quoted text per record
Corroborating signal join Can the tool require signal A AND signal B within window N to fire? Build a 2-signal compound trigger; check fire rate Must support boolean joins on signals
Action layer Does detection auto-route to sequence enrollment, rep alert, or CRM update? End-to-end test from detection to enrolled contact Must orchestrate at least one downstream action without engineering work
Cost per detection What is the marginal cost of an additional signal or additional account? Price 1,000 vs 10,000 vs 100,000 accounts monitored Should scale sub-linearly with account count

How Unify covers this. Unify Infinity Signal (/signals/infinity-signal) is a custom natural-language signal that runs on a target account list and detects activity matching a plain-English prompt. It pulls from web search, website scraping, news feeds, PDF analysis, and OpenAI computer-use — covering all 8 alt-signal categories above. Per the Introducing Unify's Next Generation of AI Agents post (Dec 2025), agents now run at 0.1 credits per run (a 10x cost improvement). Per the Deploying GPT-5 in Unify post (Aug 2025), browser-research stability hit 90% with 35% fewer tool calls. Detection auto-triggers a Play that enrolls the right contacts in a sequence — the same flow used by Flock Safety, Affiniti, Innovate Energy, and Navattic.

Which Alt-Signal Should You Run First?

Pick your first alt-signal based on your motion, ICP, and where you have the freshest data. The if/then below maps the most common scenarios to a single recommendation each.

  • If you sell into public companies with deal sizes >$50K → start with SEC filings (10-K Item 1A risk factors).
  • If you sell into regulated industries (medical, telco, defense) → start with the relevant regulatory database (FDA 510(k), FCC OET, EPA permits).
  • If you sell into deep-tech or R&D-heavy buyers → start with USPTO granted patents in your relevant CPC classes.
  • If you sell into US government or government contractors → start with SAM.gov contract opportunities filtered by NAICS.
  • If you sell into the broad SaaS ecosystem → start with conference speaker rosters and podcast guest appearances for the next 60 days.
  • If you sell into developer/infra audiences → start with niche-community posts (Reddit, Hacker News, GitHub).
  • If you have a recent product launch and need budget-reset moments → start with executive-departure press mentions, targeting 60-90 days post-departure.

How Does the Recommendation Change by Role and Motion?

The right alt-signal mix shifts materially by who is running outbound and what motion they own.

Sales (AE / BDR)

  • Lean into named-account signals (SEC, USPTO for assigned named accounts).
  • Use signals to break into Tier 1 accounts where you already have multi-thread coverage.
  • Avoid spray-and-pray alt-signals on cold lists; the personalization burden is too high for individual reps.

Growth (Growth Marketer / Outbound Quarterback)

  • Operate the full 8-category portfolio across Tier 2 and Tier 3 accounts.
  • Own the per-signal reply-rate dashboard.
  • Per Guide 1 (Outbound Sweet Spot, Unify), this is the OBQB role — sits at the intersection of Sales, Marketing, RevOps.

Marketing (Demand Gen)

  • Use alt-signals to inform paid-ad audience segments (e.g., conference speakers as a LinkedIn audience).
  • Use alt-signals to time content drops to the audience that just got triggered.

RevOps

  • Own the data-quality layer: assignee normalization for USPTO, CIK-to-CRM mapping for SEC, NAICS-to-ICP mapping for SAM.gov.
  • Define the corroborating-signal logic that fires Plays.

Regional notes

  • US: all 8 categories supported by US-facing public data.
  • EU: tighten GDPR opt-in handling. SEC equivalents (e.g., ESMA filings) are less centralized. Conference and podcast signals work the same.

What Do Real Alt-Signal Plays Look Like?

Three real customer plays, each traced from signal detection to outcome with named attribution.

Worked example 1: Flock Safety — local crime news as a signal

Flock Safety sells public-safety technology to law enforcement, schools, HOAs, and businesses — a category that is reactive by nature. The team needed to reach decision-makers at the moment a community faced an incident.

  • Signal: AI Agent monitors local news, crime reports, and social posts for relevant incidents in a target account's area.
  • Verification: evidence pulled — news URL, headline, date, incident type.
  • Personalization: Smart Snippet ties the outbound message to the specific incident.
  • Outcome (per Flock Safety case study, Unify, 2025): Michael Bergmann, Director of Demand Generation and Growth Marketing at Flock Safety: "Unify's research agents give us the context needed to get highly personal with our outreach. Their ability to zero in on the exact signals that matter most to our work in public safety is the ultimate growth hack."

Worked example 2: Innovate Energy Group — ESG language scraping

Innovate Energy Group sells energy consulting to commercial and industrial organizations and was scaling outbound into multibillion-dollar accounts without dedicated marketing resources.

  • Signal: AI Agent scrapes corporate websites and ESG reports for stated carbon-reduction goals and timelines.
  • Verification: evidence pulled — URL, quoted carbon-reduction language, target year.
  • Personalization: outbound references the stated target and offers a relevant pathway.
  • Outcome (per Innovate Energy Group case study, Unify, 2026): $15M in pipeline generated in one month, 20+ hours saved per rep per week, 8x increase in meetings booked.

Worked example 3: Affiniti — niche-vertical signal portfolio

Affiniti's TAM spans pharmacies, HVAC contractors, and auto dealerships — a fragmented audience that required niche signals per vertical.

  • Signal: 25+ native Unify signals plus AI Agents scraping per-vertical sources (inventory changes, equipment listings, fleet expansions).
  • Verification: AI Agent pulls company website, recent press, hiring postings.
  • Personalization: per-vertical sequence with vertical-specific language.
  • Outcome (per Affiniti case study, Unify, 2026): 8,700 leads prospected in 3 months, 8,000 AI Agent runs in Plays, 20+ hours saved across reps per week.

When Should You Stop or Adapt an Alt-Signal Play?

Stop or adapt an alt-signal based on the table below. These are decision rules, not opinions.

Decision rules for when to stop, pause, or adapt an alt-signal play.

Red flag Next action Wait time Channel
Reply rate below your warm-outbound floor for 2 consecutive weeks Pause sequence, audit signal verification quality 5 business days None until pattern resolves
Opt-outs >0.5% of sends Stop, review message-signal fit Permanent on current play Pause all sends
Signal fires on non-ICP >40% of detections Tighten qualification filter; require corroborating signal Immediate Same channel after fix
Single mention with no corroborating signal Do not trigger; wait for second signal 14 days observation window None
Source data >30 days old (press) or >90 days old (filings) Drop from active triggers; archive lead Permanent on this record None
More than 3 simultaneous Infinity Signal prompts active without per-signal reply rate Suspend newest signals until baselines exist 14 days to establish baseline Keep top-performing only
OOO reply Pause sequence for this contact Return date + 2 business days Same thread
Account moved to do-not-contact list Suppress globally Permanent None

What Are the Common Disambiguations and Edge Cases?

Five common confusions that distinguish alt-signals from adjacent concepts.

  1. Signal vs intent vs trigger. Signal is the observed event. Intent is the inferred state. Trigger is the executed automation rule. Don't conflate them in dashboards — they describe different layers.
  2. Material vs immaterial filings. A 10-K Item 1A line that repeats last year's risk language verbatim is not a signal. A new risk factor or one with material wording change is. Always diff to last year's filing.
  3. Defensive vs commercial patents. A patent's claims and CPC classification matter more than the existence of the grant. Defensive patents (blocking moves, no product correlation) waste outreach.
  4. Job-seeker traffic vs buyer interest. Niche-community posts from job-seekers (asking about a tool because they want to put it on a resume) look identical to buyer interest unless you verify the OP's current role.
  5. Conference attendance vs speaking. Attendance is a weak signal. Speaking is a strong signal because the abstract names the topic and the calendar moment is fixed.

What Are the Top Mistakes Teams Make With Alt-Signals?

Top 5 mistakes to avoid:

  • Triggering on a single mention without corroborating evidence. One podcast quote is a hint, not a buying signal.
  • Running more than 3 simultaneous alt-signals without per-signal reply-rate measurement. You can't optimize what you can't isolate.
  • Skipping evidence verification. If the rep can't see the source URL and quote before sending, the signal isn't ready.
  • Buying a separate vendor for each signal type. The vendor sprawl alone will cost more than the pipeline lift. Use one orchestration layer that accepts custom prompts.
  • Quoting a source verbatim in cold outreach. Reference the topic, not the literal quote — direct quotes feel surveillance-y to the recipient.

Frequently Asked Questions

What counts as an alternative buying signal?

An alternative buying signal is any verifiable, time-bound event outside the four mainstream categories (hiring, funding, web traffic, technographic) that meaningfully changes a target account's propensity to buy in the next 30 to 90 days. Practical examples include 10-K risk-factor disclosures, granted patents, government RFP postings, podcast guest appearances, conference speaker rosters, FDA 510(k) clearances, exec-departure press, and posts in niche communities like Reddit or Substack.

Why use alternative buying signals instead of hiring and funding?

Use alternative signals because the four mainstream signals are heavily commoditized: every vendor sells the same data, every BDR works the same alerts, and reply rates have compressed. Alternative signals win because fewer competitors are watching them and they correlate more tightly to a specific budget moment. Per Innovate Energy Group's published case study, scraping ESG and carbon-reduction language from corporate sites generated $15M in pipeline in one month.

How many alternative buying signals should I run at once?

Run no more than three simultaneous custom alt-signal prompts until you have a per-signal reply-rate baseline. The rationale: each new signal increases account list volume, dilutes BDR attention, and risks domain reputation damage from sending into low-fit lists. Start with one signal, measure reply rate over 14 days, then add a second only if it clears your floor (commonly 3-5% reply rate for warm outbound).

Can I get alternative buying signals without a vendor?

Yes — most alt-signal sources are public: SEC EDGAR, USPTO Public Patent Search, SAM.gov, FDA 510(k) database, FCC equipment authorization. The catch is operationalization: monitoring 50,000 USPTO grants per quarter, normalizing assignee names, filtering by classification code, and joining to your CRM is a 6-to-12-month engineering project. Most teams build a thin scraper to prove the signal works, then move to a natural-language signal platform once weekly maintenance load exceeds 4 hours.

How do I verify an alternative buying signal before acting on it?

Verify any alt-signal with at least one corroborating signal before triggering outreach. A single podcast mention is not enough; pair it with a website visit, a related job posting, a follow-up press mention, or an inbound form. Unify Infinity Signal pulls evidence (URLs, quoted excerpts, timestamps) for each detection so the rep sees the source citation before sending.

What is the difference between a signal, an intent, and a trigger?

A signal is any observable event (a 10-K filing, a website visit, a job change). Intent is a derived inference about buying readiness drawn from one or more signals (high intent on category X). A trigger is an automation rule that fires an action when a signal is detected (signal X plus signal Y inside 7 days plus ICP fit equals enroll in play Z). Signals are observed, intent is inferred, triggers are executed.

Which alternative buying signal has the highest reply rate?

Reply rate depends on your motion, ICP, and message quality, so no single category wins universally. From published Unify customer outcomes: Innovate Energy's ESG-language scraping drove $15M pipeline in one month (per Innovate Energy case study). Flock Safety's local crime-news monitoring delivered context that reps used to book meetings in minutes rather than days (per Flock Safety case study). Both were custom alt-signals, not off-the-shelf intent feeds.

When should I stop running an alternative buying signal?

Stop or pause an alt-signal when reply rate falls below your warm-outbound floor for two consecutive weeks, when the source data goes stale (older than 30 days for press, older than 90 days for filings), or when opt-outs exceed 0.5% of sends. Other stop conditions: signal fires on a non-ICP segment more than 40% of the time, or you cannot find a corroborating signal for the majority of detections.
