For investors
Technical due diligence that reads the same across every deal.
So much software is now written by AI that a founder's assurance is not enough on its own. StackAttest gives you a consistent, evidence-based read on technical readiness, shared as a Passport, so you compare companies instead of decks.
Evidence, not assurances
A Passport shows what was checked against the live app, repository, dependencies, and runtime, with a grade for the strength of each control's evidence.
Consent-gated diligence
Request the report sections you need. The founder approves or declines the request, can set an expiry, and can revoke access later.
Comparable without flattening
The same four signals and L0 to L5 ladder apply across companies, while uncovered controls stay visible instead of being treated as passes.
Answers tied to evidence
The questionnaire assistant drafts common security and diligence answers from verified facts, with citations back to the Passport evidence.
How it works for you
Request selected access
Ask for specific Passport sections and state the purpose. The request grants nothing until the founder approves it.
Read the evidence and gaps
The Score, Evidence Coverage, Validation Confidence, AI Consensus, and ladder level show both the result and the limits of what was proven.
Export the diligence record
Use the consent-bounded due-diligence report and questionnaire drafts to focus follow-up questions without asking for raw source.
Track it over time
Consent-bounded change alerts report score, level, readiness, freshness, and blocker movement. Portfolio monitoring also shows shared Passport history when the founder grants it.
What you receive, and what you do not
Access to a company's technical evidence is granted rather than bought. That constraint is the reason founders share anything real, so it is worth being exact about both halves of it.
What you receive
- The Passport sections the founder granted for the purpose you stated, with the evidence grade behind every result.
- Uncovered controls, still listed as uncovered. A gap you cannot see is worse to you than one you can.
- The same four signals and the same L0 to L5 ladder for every company, so two reads sit on one scale.
- A consent-bounded diligence export and drafted questionnaire answers, so your follow-up questions start from what was actually tested.
What you do not receive
- Source code. It is not part of any section, at any level of access.
- Anything the founder did not grant. Sections are an allowlist, and one left out of the grant returns nothing.
- Anything before the founder approves your request, and nothing after it expires or is revoked.
- A recommendation. This reports technical evidence, and supplements the review you and your experts still run.
