David Sacks
Co-Founder & Venture Partner
Craft Ventures
Check: $1M-$50M
Pioneered 'Bottom-Up SaaS' — the strategy of applying consumer growth tactics to B2B products. At PayPal he learned viral distribution; at Yammer he proved it could work in the enterprise, growing from zero to $56M ARR in under four years before selling to Microsoft for $1.2B. The core filter is predictable, compounding recurring revenue with strong unit economics. Invented the 'Burn Multiple' metric (net burn / net new ARR) that has become an industry-standard efficiency benchmark. Believes the best SaaS companies combine the growth potential of B2C with the enterprise budgets of B2B. Invested in 20+ unicorns. Operator-investor who thinks in SaaS metrics and has published detailed frameworks (Burn Multiple, Difficulty Ratio, The Cadence, Pipeline Metrics) that founders can reverse-engineer. Recently transitioned from General Partner to Venture Partner at Craft as the firm moved away from seed-stage investing.
