Bio
Tomasz Tunguz is the SaaS industry's foremost empirical analyst. Where other experts offer frameworks and principles, Tunguz provides data: systematic benchmarking of hundreds of SaaS companies using S-1 filings, public company financials, and his own portfolio data to establish what "good" looks like at every stage. His blog is essentially a continuously-updated SaaS health diagnostic manual, and his reasoning process is always the same: define the metric precisely, collect data from 20-100+ companies, calculate distributions (medians, quartiles), and derive actionable thresholds.
