PASS: vaporware demo — slick video, no repo, no product
Founder Score
A running score for this person, not this pitch — it persists across applications and never resets to zero.
58May 01, 25
Inbound — cinematic product demo video, strong narrative
29May 03, 25
No public repo, no API, no named customer found on any channel
3-Axis Score
Founder, market, and idea-fit are scored independently and never averaged — disagreement between them is signal, not noise.
Founder
Is this person capable of pulling this off?
26declining
The demo video shows a UI mockup, not a live system — no repo, no API surface, no infra footprint of any kind found. In the Arena, could not describe the system's actual architecture.
2 evidence points backing this score
Market
Is this a market worth building a fund-scale outcome in?
58stable
Autonomous research automation is a genuinely hot category — the market thesis itself is fine, independent of this team's ability to execute it.
Idea vs Market
Does the specific idea survive contact with that market?
24declining
Idea does not survive scrutiny given zero evidence of a working system; no signal the team can build toward the claim.

Legibility
A great talker and a great builder can score the same on a deck. This strips out how well the pitch was told, and scores what was actually built.

Polished · how good it sounded in the room61
Correction applied — the gap between substance and delivery is removed.
