13 founders in stealth, matched to how you actually invest

Ten and a half years at DoorDash, ending as Head of In Store. Before that Group PM and Head of Merchant Logistics.

SignalDark. No domain, no description, one person on the record. Left in January and the stealth company starts the same month. Nothing raised. Of everyone here this is the best combination of timing and fit.

Co-founded Octaura, the Citi-backed electronic trading venue for syndicated loans and CLOs. Before that ran Markets Strategic Investments at Citi for five years. Board seats at Trumid, Genesis Global, Arteria AI. Princeton.

SignalHeadline reads “Founder and CEO at Stealth Startup.” Direction stated as fintech for credit markets — consistent with Octaura and her Citi years. The only candidate whose stealth description is real signal rather than a database artifact.

Ten years of supply-chain and operations software: Director of Product at Resilinc for six years, Product Lead at Flexport, Principal PM at Gusto. Co-founded Eon Info Solutions before that.

SignalSays it in his own headline: building an AI operating system for construction. Sector public, product dark. Full time since March 2025.

Founding engineer at Vori (grocery software) and senior engineer at Instacart.

SignalNot dark — rapide.io is live: agentic AI running the retail back office, cost, pricing, ordering, inventory and receiving, for grocery and multi-vendor retail. No round on record, but there is a login and an outbound sales motion running. If you want this one, the window is closing.

Founded Medsaf and ran it eight years — venture-backed pharmaceutical supply chain fighting counterfeit drugs and hospital procurement. Then Director of Product Management at Pfizer.

SignalCEO of a stealth company since April 2026. Headline states the domain: supply-chain infrastructure in complex markets. One check needed — her Pfizer record carries a future end date, so confirm she is fully out.

Senior Engineering Manager on AWS Control Tower at Amazon, and before that Managing Director at Deloitte. Also ran AWS solutions architecture for financial services and professional services at Check Point.

SignalHeadline says he is building something new in cloud security. Nothing raised, three months out — the earliest catchable person on this list. Worth testing whether the wedge is compliance for regulated customers or generic security tooling.

VP and Head of Clinical Data Science at Prolaio (AI cardiac care). Google Health AI resident. Stanford PhD, Edinburgh MBChB.

SignalHeadline is unambiguous: “Health x AI Founder.” Clinical AI in regulated care. Product dark. Needs a commercial co-founder — he has never held a P&L role.

VP of Data, AI and Robotics Platforms at Moderna. General Manager of AWS Supply Chain at Amazon, after six years running Amazon grocery supply-chain technology.

SignalDark, unfunded, five months out. Pharma manufacturing plus supply chain is the regulated-physical-industry pattern almost exactly. One thing to ask: four roles in two years, and an earlier founding attempt he abandoned inside twelve months.

Co-founder and COO of Vectrix (YC S20), acquired by Cloudflare in 2022. Stayed four years at Cloudflare on product. Security background at Autodesk and PlanGrid.

SignalHeadline says “Stealth AI Startup.” Direction is data security and AI. Clean break in May 2026 — the post-acquisition tenure ended and the stealth record started the same month.

Founded Antidote (formerly TrialReach) and ran it a decade — clinical-trial matching, venture-backed. Co-founded Kelkoo, sold to Yahoo for about €475M. Later VP Digital Strategy and M&A at IQVIA.

SignalFounding again as of January 2026, not advising — we checked, the “advisor” in his headline is historical. Product dark. The risk here is the reverse of usual: with a Kelkoo exit behind him he may not want a first check.

Senior Staff Engineer at Instacart, marketplace engineering at Lyft, VP at Morgan Stanley. Co-founded and was President of Highstock.

SignalDark. Headline is “Building something new.” Highstock ran fifteen months and ended July 2025 — worth asking how it ended before the meeting.

Director of Engineering at Credit Karma. Before that co-founder and CTO of SeedFi, consumer lending, venture-backed.

SignalTwo overlapping records, almost certainly one company. Direction is browser-task automation, which is horizontal — the regulated-fintech engineering record is the reason he is on this list, not the current product. He is CTO, so someone else is CEO.

SVP and General Manager at hims & hers, running a telehealth P&L. Five years as a GM at Uber, Senior Director at Spotify. West Point, HBS, US Army Cavalry captain.

SignalCo-founder and CEO of a company called Vael since January 2026. We could not confirm what Vael is — the one domain that matches does not name him. Strong operator, unconfirmed company.
