How it works

From deck to verdict in four steps

  1. 1

    Order and brief us

    Pick a tier, share the deck, round terms and the questions that matter to you. Your documents stay private to your order.

  2. 2

    Sourced research

    AI researches the company, founders, market, traction and terms. Every factual claim carries a source, or is marked unverified.

  3. 3

    Analyst sign-off

    An analyst edits the draft, scores the rubric and writes the verdict. Nothing reaches you without human approval.

  4. 4

    Your memo

    A branded PDF with a clear verdict: Strong Interest, Proceed with Caution, or Pass. Delivered to your portal.

The investor playbook

Judgement distilled from the best investors

Best practices and decision-making from the best angel investors and family offices are used to create the reports, a competitive edge that no other due diligence tool can provide.

Every report is assessed against a curated, source-checked library of how seasoned business angels, venture capital investors and family offices evaluate teams, markets, traction and deal terms. Your analyst applies it to your deal and your questions.

    How experienced angels read founders, early traction and risk before writing a cheque.

  • Family offices

    Long-horizon thinking on governance, alignment and capital preservation.

  • Venture capital

    Market sizing, competitive dynamics and terms benchmarked against the stage.

Pricing

Standards

Built for decisions you have to defend

Sourced, not guessed

Claims link to their source. What cannot be verified is labelled as such, never filled in.

Human verdict

The final recommendation is written and approved by an analyst, not generated.

Confidential by design

Decks and data rooms sit in private storage with short-lived links and role-based access.

EU data residency

Database and files are hosted in Frankfurt. Your materials are used only for your own order.
