John Luttig started as an intern at Founders Fund nearly a decade ago and grew into a partner role there, giving him an unusually long apprenticeship within the same firm's culture and investing style. He writes widely-read analyses of software companies and publishes a weekly newsletter sharing what he's learned and questions he's thinking about, building a reputation for deep thinking on SaaS metrics and startup strategy that founders study as thought leadership.
