After a startup fails or you exit, dedicate time to writing a detailed, private postmortem. Critically analyze interactions, decisions, and outcomes. This exercise helps transform painful experiences into a concrete set of operating principles for your next venture.
When you can no longer genuinely sell your startup's vision to employees or investors because you've lost faith in its mission or viability, it's a sign to leave. This internal conflict, or cognitive dissonance, is detrimental to the company and your own integrity.
Working at Google conditions you to take user acquisition, talent recruitment, and marketing for granted. When ex-Googlers start companies, they are often unprepared for the fundamental challenge of getting anyone to care about their product, a skill they never had to develop.
To build a truly product-focused company, make the final interview for every role a product management-style assessment. Ask all candidates to suggest product improvements. This filters for a shared value and weeds out those who aren't user-obsessed, regardless of their function.
Don't start a company in a space you're indifferent to and ignorant of. Your founding idea must be anchored in either deep domain expertise ("what you know") or a genuine, intense passion for the problem ("what you care about"). Lacking both is playing on "extra hard mode."
Create a public document detailing your company's operating principles—from Slack usage to coding standards. This "operating system" makes cultural norms explicit, prevents recurring debates, and allows potential hires to self-select based on alignment, saving time and reducing friction as you scale.
Friends provide biased feedback. For a truer market signal, launch a waitlist for your product on a relevant, niche online community like Hacker News. The volume of sign-ups from your target audience provides a far more realistic and valuable measure of initial demand than conversations with your personal network.
It's possible to raise significant late-stage funding without revenue if you can demonstrate deep, sticky product love from a valuable user base, like developers. For investors like Sequoia, proving you've captured a hard-to-win market can be a more compelling signal than early revenue metrics.
