Guesser

Guesser was a startup surfaced as a portfolio company of version-one-ventures and added to the API Evangelist network as a stub for enrichment. Per Version One Ventures' own portfolio listing, Guesser was acquired by Gemini in 2021 and no longer operates as an independent company. During the enrichment pass no live company website, developer portal, API documentation, OpenAPI, SDKs, or other public developer surface could be located (its likely domain guesser.io does not resolve), so no provider artifacts were produced. This profile is retained as a historical/acquired-company record.

Guesser is profiled on the APIs.io network. Tagged areas include Company, Acquired, Startup, Prediction, and Gemini.
