Forms & parts of speech
Who he is, in plain terms
David Skok is the serial founder (four companies, three IPO-or-acquired) turned Matrix Partners general partner whose blog forEntrepreneurs quietly became SaaS's measurement constitution. His "SaaS Metrics 2.0" essay and "Why Startups Fail" deck gave the industry its shared definitions — and its hurdle rates.
The key ideas
The SaaS cash-flow trough — subscription businesses lose money on each customer before payback, so growth consumes cash in proportion to its speed; the two ratios that decide viability — LTV should exceed 3x CAC, and CAC payback should land under 12 months for capital efficiency; negative churn (expansion revenue outgrowing lost revenue) as the most powerful force in SaaS; and unit economics as the go/no-go gate — scaling a business with broken per-customer math just industrializes the loss.
Why he still matters
When a board asks for magic number, NRR, or payback by cohort, it is speaking the dialect his essays standardized. The benchmarks have aged into furniture — argued about, adjusted for PLG and usage pricing, but still the starting point — and his core warning still kills more pitches than any other: growth is only worth funding when the unit math works.
