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.
