Chipstack
Chipstack is an AI-driven semiconductor verification company that uses agentic AI to automate chip design verification, one of the most time-consuming stages of building a complex chip (often 60% or more of total development effort). Its product suite is a set of specialized AI agents — a Mental Model AI Agent, a Formal AI Agent, a Unit Simulation AI Agent, and a UVM AI Agent — that read design intent and generate, run, and reason about verification tasks to shift that work earlier in the design cycle and cut the time and resources it takes to tape out. Founded and based across Seattle, WA and San Jose, CA, and backed by Khosla Ventures, Chipstack is an enterprise, demo-request product rather than a public developer platform: as of this profile it publishes no public API, developer documentation, SDK, or developer portal. In 2026 the company announced it is joining Cadence. This profile is maintained in the API Evangelist network for discovery and monitoring.
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 Chipstack 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 — Chipstack scores 12.3/100 (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.

How we profile Chipstack
Each block below is one kind of artifact we hold for Chipstack. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
