Sierra Ventures

Day-to-day investment decisions sit with the three Managing Partners: Mark Fernandes, Tim Guleri, and Ben Yu. The firm also employs Partners Vignesh Ravikumar and Shomik Ghosh, and Venture Partner Shashank Saxena. Founder Peter Wendell remains involved as an advisor but the current leadership team drives deal execution and portfolio management.

Sierra leans on a dedicated CXO Advisory Board that includes C-suite executives from ServiceNow, LinkedIn, Snowflake, and Perplexity, alongside an Engineering and Product Leaders council. These networks supply early visibility into enterprise adoption trends and founder references, while the firm's ASCEND content platform and CXO Summit function as top-of-funnel relationship engines that keep Sierra in front of technical operators before they start companies.

Sierra Ventures is a traditional venture capital firm, not a family office. It raises early-stage funds from institutional limited partners and has operated through multiple fund cycles over four decades. The firm's headquarters are in San Mateo, California.

Sierra Ventures makes direct investments into companies from inception through Series A. There is no public evidence that the firm participates as a limited partner in other venture funds or pursues a fund-of-funds strategy. Its model is built around active board-level engagement with portfolio companies rather than passive fund commitments.

The firm invests from inception through Series A. Its stated check sizes are up to $5 million for seed-stage deals and up to $10 million for Series A rounds. Sierra describes its posture as 'come early and stay late,' signaling a willingness to lead initial rounds and support companies across multiple subsequent financing events.

Peter Wendell founded Sierra Ventures and remains listed as Founder & Advisor. The current investment leadership — Managing Partners Mark Fernandes, Tim Guleri, and Ben Yu — now runs the firm day-to-day. Jim Doehrman is also listed as an Advisor. The advisory roles suggest a multigenerational leadership transition typical of venture firms that have operated through several fund cycles.

Sierra does not publicly market a co-investment vehicle or a dedicated fund for participating alongside other general partners. Its investment activity focuses on direct seed and Series A deals where Sierra acts as a lead or co-lead investor, often utilizing its CXO network and operating team to add value post-investment. External co-investor relationships, when they occur, are structured on a deal-by-deal basis.
