Sierra Ventures is an early-stage venture firm centered on B2B companies, with strongest conviction in Seed and Series A enterprise software and infrastructure investing. The firm backs founders globally, often as the first institutional check, and combines stage-specialist investing with hands-on support and a CXO advisory network designed to accelerate enterprise customer access.
Sierra looks for B2B SaaS businesses that demonstrate a sticky product (gross retention 90‑95% and net retention 120‑140%), efficient go‑to‑market (CAC payback <12 months), and a clearly defined ICP. Founders with deep domain expertise and early design‑partner traction are heavily weighted. The CXO Advisory Board provides early customer insight, validates market need and can open enterprise buying doors, making it a core part of the diligence process. Deal‑breakers include weak customer pull, ambiguous ICP, poor retention metrics, or inefficient payback periods. While the firm will back exceptional teams anywhere on the planet as the first institutional check, it expects repeatable GTM dynamics before committing larger Series A capital.
