Insitro is a machine-learning-driven drug discovery company with a workforce of roughly 300 people. Over the most recent twelve-month period the team size held steady, as 31 new employees joined and a similar number departed. The balanced hiring and attrition suggest the organization is maintaining a consistent operating cadence while it advances its research and platform development.
Engineering is Insitro’s largest function with 168 employees, or a little more than half of overall headcount, underscoring the company’s data- and software-centric approach to biology. Business Management (31 people) and Finance & Administration (22) provide operational support, while Information Technology and Human Resources each account for 16 employees. Additional expertise is distributed across Healthcare (13), Operations (12), Marketing & Product (8), Education (2), and an assorted "Other" category (13). Hiring and departures were spread across functions, resulting in a net-neutral change in every major department.
Insitro’s footprint is concentrated in the San Francisco Bay Area, with 157 employees in San Francisco proper and smaller clusters in Redwood City, Palo Alto, and San Jose. Beyond the Bay Area, the company maintains modest teams in New York, Boston, Seattle, Cambridge, and Krakow, while an "Other" grouping of 102 employees reflects a mix of remote and satellite contributors. The distribution highlights a hybrid model that anchors scientific and engineering talent near Bay Area research hubs while tapping into specialized skill sets in other biotech and technology centers.
