Andreessen Horowitz Tech Stack

Venture capital firm investing across seed to late-stage technology companies

Venture Capital and Private Equity Principals Menlo Park, CA 201–500 employees Founded 2009 Privately Held

Andreessen Horowitz operates a stage-agnostic venture platform with a tech stack reflecting operational maturity (GCP, PostgreSQL, Okta, HubSpot) rather than cutting-edge infrastructure bets. Active hiring skews toward senior roles and operations (engineering, ops, finance, HR, marketing all at similar volume), indicating scaling of internal infrastructure and LP management rather than pure deal sourcing — a pattern confirmed by projects focused on fund formation modeling, investor communications, and operational playbooks.
