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.
