Sierra Ventures
Sierra Ventures is an early-stage venture capital firm founded by Peter Wendell in 1982 and headquartered in San Mateo, California, in the heart of Silicon Valley. The firm invests from inception through Series A in first-principles founders under the tagline "Conviction Before Consensus," writing checks of up to $5M at seed and up to $10M at Series A. Sierra's current investment thesis centers on the next wave of enterprise technology: Vertical AI (purpose-built AI for specific industries), Infrastructure AI, Frontier and Deep Tech, and Physical AI and Robotics, alongside a longstanding history in enterprise applications, digital health, SaaS, and security. Over its 40-plus-year history the firm has invested more than $2 billion across 13 early-stage funds, with its 13th fund closing in 2023 at $265 million, following Fund 12 at $215 million and Fund 11 at $170 million. Sierra reports 35 IPOs and hundreds of successful exits, having backed companies such as Elastic, Astronomer, Chronosphere, CourseHero, Q-CTRL, Spectro Cloud, Endor Labs, and Reflection AI. The firm is notable for its CXO Advisory Board of Fortune 1000 enterprise leaders who help portfolio companies land early customers. This profile tracks Sierra Ventures' identity and its portfolio graph across the API Evangelist network.
Sierra Ventures is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Sierra Ventures is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
