CB Insights analysis identifies serial entrepreneurs moving to stealth AI projects
Market intelligence firm CB Insights has tracked 17 former AI 100 startup founders and key team members who are now developing new ventures in stealth mode.

CB Insights utilized internal data to monitor the career trajectories of individuals previously associated with high-growth AI companies. By analyzing professional histories, research publications, and public disclosures, the firm identified a group of 17 founding members who have transitioned into undisclosed projects. This trend highlights the recycling of technical talent from successful past exits into nascent, unannounced ventures.
The report examines how the expertise of these individuals serves as an indicator for their current focus. For example, former engineers from firms like Onfido and Common Sense Machines are applying previous experience in identity security and spatial computing to address modern challenges in fraud prevention and 3D modeling.
Other notable transitions include former leaders from Luminous and Algolia, who are pivoting toward hardware infrastructure and real estate sector optimization. By identifying these patterns, analysts can anticipate shifts in the AI startup ecosystem before these ventures officially launch or secure public funding.
