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.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Basis Set Ventures the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Basis Set Ventures scores 7.2/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.
