MentionFox spotted these new ex-Stripe founders this week. Did your competitors?
3 watchlists free. No card required.
Three steps from blank page to your first founder spinout.
Stripe. Anthropic. Figma. OpenAI. Plaid. Any company whose alumni you want to follow. Bring as many as your tier allows.
MentionFox builds the roster of ex-employees from public signals. No scraping behind logins. The roster updates as people change roles.
Each new founder, the new company, the stage if known, and one-click links to vet the founder or find their email.
A snapshot of what an Alumni Tracker watchlist looks like for a Stripe and Anthropic watcher.
Recent: 3 new ex-Stripe founders. 1 new ex-Anthropic founder.
Each row in your real watchlist links straight to a founder vetting dossier and a contact-finder.
Start free. Upgrade when you outgrow three watchlists.
Live tier prices on the main pricing page.
Two principles we hold to. The third one is up to you.
The same alumni-watching pattern that proprietary deal-sourcing teams build internally — now in your inbox without the five-person research desk.
No scraping behind logins. Every spinout is sourced from publicly accessible signals: launches, public press, public maker activity. You can verify each one.
