CrucibleStartup Diligence
v1 cohort open · free score + brief

Startup ideas go in. Forged or broken comes out.

Other AI tools score your idea in 30 seconds. Crucible runs an agentic deep dive of institutional-grade diligence with frontier models, the way a real investment committee actually would — every claim cited, every validation measured — then tells you the cold hard facts of whether the idea survives it, and how to best sharpen it.

04 Deep Diligence

1 build. 14 analyses. 30+ frameworks.

A build coordinates the full battery — fourteen agentic research runs, every claim searched, sourced, and cited — then unblurs the Brief section by section and re-grounds every score against what it found.

What a build runs

Adversarial research — it hunts the disconfirming evidence too.

Customer & segments, founder DD, regulatory, technology & IP, timing, comparables, market sizing, competitive, pricing, willingness-to-pay, unit economics, go-to-market, and deal terms — synthesized into a readiness read and the Investor Memo.

Sourced, line by line

Clickable citations behind every material claim — no assertion without a source, or an honest “evidence absent.”

every claim cited

The Risk Read

Six risk calls — founder, regulatory, technology, timing, execution, terms — each scored, explained, and tied to its analysis.

Grounded in your materials

Drop decks, financials, research at kickoff — the build reads them first, and flags when they change.

06 Tempered by Stage

An idea isn't judged like a funded startup.

The read scales its skepticism to maturity — idea, concept, building, in market, funded. A napkin sketch is scored on potential; a funded launch with no traction takes the full heat. Stage is auto-stamped from the evidence — an SEC Form D filing, live market signals — or set it yourself.

Stage-scaled judgment

The same idea scores differently — at the stage it's actually at.

Five gates from idea to funded. The validation penalty dials up with each one, so early ideas aren't punished for evidence they couldn't have yet — and launched companies can't hide behind “early.”

The maturity dial

Severity tracks how far the build has outrun the evidence — a napkin and a funded company face different heat for the same missing proof.

idea ≠ funded

Evidence that moves scores

Log what public research can't see — pilots, subscriptions, LOIs — and fold it into the read in one explicit, audited recalibration. Nothing moves silently.

07 Investor Memo

The verdict, defended — like an IC would write it.

The synthesis at the top of the ladder: kill cases argued from the evidence, the recalibrated verdict, and the three forged directions — exportable, and defensible when the committee pushes back.

The synthesis · reads everything

“Two kill risks — both addressable.”

The memo pressure-tests every built module against the findings — where a claim is unsupported, it says so, with the source that broke it.

Kill cases, argued

The objections surface now — named incumbents, broken economics, regulatory walls — not mid-pitch.

Investor-grade rigor — at software speed and cost.

10 Pricing

Pay for deep diligence, not ideas.

Journal unlimited ideas, blink-score them all, and read every Concept Brief free — a credit is only spent when you send a concept into Deep Diligence.

How Crucible credits work — like Audible, for venture diligence.

1 credit = 1 build

One concept, taken all the way through the crucible. Browsing, blink scores and Concept Briefs are free — a credit is spent only when you forge a full Deep Diligence build.

Pay as you go, or join a tier

No membership? Buy credits one at a time at $99. Join a tier and every credit costs less — the more you commit, the lower the price.

Credits land in your account

Monthly drops a fresh bundle each month; Annual and Early-Believer prepay at a deeper rate and load the term. Unused credits roll over — they are yours.

Top up anytime, at your rate

Run dry before the next bundle? Buy more credits at your tier's price — never back at the $99 a-la-carte rate.

Buy credits in bulk — the more you commit, the less each one costs.

10 Q&A

Questions, answered.

Decisions without sources are innovation theater. Here's the honest answer to every alternative.

ALT · 01

Why not just ask a frontier AI model yourself?

It’ll sound brilliant in seconds — but a chat keeps no sourced evidence trail, and no track record it’s measured against. Crucible is the system around the model — auditable diligence, calibrated on real studio outcomes.

ALT · 02

Why not Notion + Airtable + Miro?

A place to write things down — no source discipline, no kill paths, and nothing that builds on itself. Every studio that starts here rebuilds it; Crucible is already that system.

ALT · 03

Why not build it in-house?

18–24 months of engineering and upkeep to reinvent it — with none of the cross-studio learning. Build ventures, not the platform that builds them.

ALT · 04

Why not hire a consulting firm?

Service-dependent: the capability walks out when the engagement ends, and the evidence stays on their laptops. Crucible is the institutional memory — it stays and compounds across your portfolio.

TRUST · 01

Who can see my idea?

Your workspace is walled off by row-level security — no other customer, human or AI, can read your concepts. The isolation test suite runs in CI on every release; if it fails, nothing ships.

TRUST · 02

Does my idea train a model or leak into benchmarks?

Nothing you submit is shown to another user or fed into a shared model. Any benchmark we build is anonymized aggregate only — with no link back to your workspace, by schema, not by promise.

TRUST · 03

Who owns the output?

What you submit and what we generate for you is yours: exportable memos, full version history, deletion on request. Concepts are processed by enterprise AI APIs that don't train on your data. We never train on the content of your ideas either — our scoring calibration learns from anonymized, aggregate outcomes only, never from what you wrote, with no link back to your workspace.

12 Origin

Built by an operator, in production first.

A decade of venture building — fund diligence, studio company creation, university venture programs — systematized into the tool its builder always wished existed. Crucible is the refining fire: it either breaks your idea, or hardens it to withstand the heat. The full story →
