Find companies your competitors can't see yet
Specter and Harmonic give you 100 leads. Foxhole gives you 3 — with the three-sentence opener that proves you read the founder's work.

Engineering acceleration

Commit cadence doubling three to six weeks before fundraise announcements. The pattern shows up in public repos long before any wire hits.

Operational scaling without VC

Hiring a Controller plus RevOps plus an SOC2 lead — while still bootstrapped. The signature of a company preparing to handle enterprise contracts on its own balance sheet.

Founder maker history

Serial bootstrapped builders shipping their fourth product, not their first. The track record predicts which lean teams will actually scale.

Cross-platform pain signals

Emerging categories surfaced from forum conversations, GitHub issues, and product communities — before the companies that solve them are formed.

Know the founder before the partner meeting
Not a Google search. Not a LinkedIn skim. A verified, sourced portrait of the founder, their network, their reputation, and their track record — every claim cited.

Career & company arc

Current and prior roles, companies founded, exits, board seats, advisory positions. Verified across multiple sources, timestamped.

Public reputation & sentiment

What employees, customers, and the community say. Aggregated sentiment with source links to original conversations.

Network mapping

Co-founders, frequent collaborators, prior investors, advisors. Relationship signals beyond what's on LinkedIn.

Track record signals

Shipping cadence, fundraise history, technical contributions, patent filings, speaking engagements. The signal pattern of a founder who actually executes.

Watch the alumni of any company
Add Stripe, Anthropic, Figma, OpenAI — or any company. We surface ex-employees the moment they start something new. Weekly digest. 3 watchlists free.
Built for three buyer types

Seed and Series A VCs

Find founders before they pitch. Get a three-sentence opener that proves you read their last commit, not their landing page.

Family offices and solo GPs

Proprietary deal flow without a five-person research team. The signal does the legwork; you focus on the conversation.

PE roll-up funds

Bootstrapped companies entering operational scaling are ideal acquisition targets. Find them while they're still off-radar.

Try it. First dossier in 5 minutes.
