Stealth Startup Spy #363
Ex-People Data Labs CEO builds identity infra for the agentic economy, 3x founder (Slingshot Biosciences, Radiant Genomics, Pattern Ag) enters stealth, & Google alum builds AI-native chip design tools
🚀 We just launched a new newsletter — Company Launch Tracker.
We’re tracking company launches as they happen and surfacing the most interesting new founders and startups (yes, all outside of this stealth activity too). If you want to stay ahead of the curve, this is where you’ll find them first.
Right now we’ve got 5 subscribers: my wife, my mom, and that high school buddy who won’t stop pitching me his app. Be smart like them and get in early 👇
We run a live feed inside Gravity that tracks founders entering stealth and companies quietly exiting it.
What you’re reading here is about 1% of the stealth activity we pick up. The full tracker updates in real time as things change and new activity emerges.
If you want earlier access to everything, book some time with us to stay ahead.

Former People Data Labs co-founder and CEO is building identity and trust infrastructure for the agentic economy

🚨Here’s the deal🚨This email has gotten too big. Exciting, but with more people following it, the edge diminishes. I’ve thought long and hard about what to do to preserve the value in the signals. I’m not sure about the final direction yet, but in the meantime I’ve been sending an email 48 hours earlier to a select group of paid subscribers. The feedback has been pretty positive so I’m going to open up the list for another 100 spots. To get signals early, Apply here!
Stay Stealthy,
