Your investor workspace — Foxhole feed ranked by signal strength, founder dossiers, deal memos, warm-intro paths, and portfolio watch. Each card explains why it surfaced today.
A founder doubled their commit cadence three weeks ago. Another quietly hired a Controller and an SOC2 lead while still bootstrapped. MentionFox surfaces them before Crunchbase, hands you a founder dossier where every claim is cited, and runs your pipeline, memos, and warm intros without bolting four tools together.
No credit card required · First founder dossier in 5 minutes · See pricing after trial
Verified, sourced, every claim cited.
MentionFox for investors sources bootstrapped founders before Crunchbase from public signals, vets any founder with a sourced and cited dossier, and runs dealflow, deal memos, warm-intro paths, and portfolio watch in a single workspace — for VCs, angels, scouts, and PE.
"Non-profit publishing platform. Open-source flagship. Engineering output has roughly doubled in the last month and a half."
"Privacy-first analytics shop just posted a Controller plus a RevOps role plus an SOC2 lead — while still taking no outside money."
"Image-and-video generation API, indie-built, quietly added customer-success and RevOps roles in the last 30 days."

Foxhole reads four signal classes — engineering acceleration, operational scaling, founder maker history, and emerging-category pain — to surface bootstrapped companies before they appear in any private database.
Founder Vetter builds a sourced, cited dossier: career and company arc, public reputation, network mapping beyond LinkedIn, and track-record signals. Every claim links back to where it came from.
Spin a deal memo from a company you're evaluating — thesis, concerns, weighted conviction, and the asymmetric plays only you can run. The structured memo behind your next yes.
Find a citable warm-intro path, draft the three-sentence opener, and track every founder in your pipeline. Nothing sends on its own — you review and send each message yourself.
A signal database with hundreds of companies per query. You still export the list, decide who's worth a message, write each opener from a blank page, and chase contact details in another tool. Volume without a reason to reply.
Strong company graph and growth tracking. But it stops at the list — vetting the founder, writing the personalized opener, and running the deal memo all happen somewhere else, across two or three more subscriptions.
Surfaces three companies that match your thesis today → vets the founder with a sourced, cited dossier → drafts the three-sentence opener that references their real work → tracks it in your pipeline and memo. One login. See pricing.
Proprietary deal flow. Subscribe to your thesis and get a daily feed of bootstrapped companies entering enterprise scale before they hit Crunchbase — ranked by signal strength, each with the reason it surfaced today.
