Discussed in terms of potential acquisition by OpenAI for $3 billion, with an ARR of $100 million at the time. observed
No person- or entity-level identity check is on record for this company. A name match is not one.
The inclusion bar: two or more independent sourced evidence families. This profile is published and listed. It is a statement about how much evidence we hold, and about nothing else.
We have not established fit. That is not a soft no and not a soft yes — it is unknown, and it is never counted as a qualified prospect.
UNKNOWN (not a soft no, never counted as qualified). Blocker: No source states a band-bearing stage for any financing event we hold.
What would overturn this:
Assessed 2026-10-24 for seed/Series-A sourcing.
Five evidence lanes (activity, capital, infra, hiring, ecosystem) as within-cohort percentiles, combined with evidence-breadth weights over the 60-company baseline cohort. The ± band widens with missing lanes — it measures what the score stands on. Scores publish at 2+ evidence lanes; this company's tape carries 1 (0 signals/60d), so no number is claimed.
No standout signal or flag yet.
The skeptic's read what this company has said, judged against what happened
Sharpest miss on record: “OpenAI will acquire Windsurf for approximately $3 billion.” — No record of OpenAI acquiring a company named Windsurf for about $3 billion, and no such acquisition has been announced or reported in any reputable source.
Unproven ≠ false — it means the deadline or the evidence hasn't arrived. Nothing here is editorial: every count is a ledger row you can open on the Proof page.
No single number decides. Layers can disagree — that's the point. New to this? →
The platform's own early signals for this company — hard-to-fake, and where one preceded a real raise, the measured lead.
as a single programmer, you could probably switch between Cursor, WindSurf and, you know, Replit and a few others, but as a, as a network of 500 engineers in a company, and I've done embeddings on the whole code base and, and I'm, I'm talking to all the different, you know, systems it's wired up to, wow, change management on that, you know, becomes a lot harder.
what you're seeing in, you know, cursor, windsurf, uh, replit, you know, level of bolt, et cetera, like obviously, you know, probably different use cases, like probably 80% of the vibe coding is more fun and it's interesting to watch and not going into production, but I could see a lot of, you know, product market fit for, Hey, I have this internal IT tool.
When you look at Windsurf, they're going to have to build their own models.
I think there's a tiff between Windsurf and Anthropic, where Anthropic cut them off to all their models. You know, Windsurf was bought by OpenAI. Not that surprising, but just seeing these walls pop up.
