Basis Set Ventures

Basis Set Ventures is an AI-native, early-stage venture capital firm founded in 2017 by Dr. Lan Xuezhao and headquartered in the San Francisco Bay Area. The firm invests at the seed and early stages in founders building artificial intelligence across AI infrastructure, autonomous systems, molecular and materials discovery, agentic development tooling, intelligent collaboration, and automated workflows. Basis Set announced a $250M Fund IV and describes itself as "the first capital when it's just you and your vision," pairing capital with an operator-led founder concierge team. Portfolio companies include Path Robotics, Quince, Sakana AI, Tigris Data, Mem0, OpenArt, Cusp, Simular, Vizcom, and Entire. This is an API Evangelist network profile of the firm; Basis Set Ventures does not publish a public API, developer portal, or SDKs, so this record captures firm identity, web properties, and derived security posture rather than API artifacts.

Basis Set Ventures is profiled on the APIs.io network. Tagged areas include Company, Venture Capital, Artificial Intelligence, Machine-Learning, and Seed Stage.

Basis Set Ventures’ developer surface includes engineering blog, YouTube channel, and 8 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/basis-set-ventures: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
