How Geoff made his way into the world of technology and startups, came to found Imagine K12 and how that led to becoming President @ Y Combinator today? 2.) What were Geoff's biggest takeaways from seeing the boom and bust of the macro environment in the dot com and 2008? How did those times impact both his operating and investing mentality? Why does Geoff believe 2000 was "purifying"? Why can the same not be said for 2008? How was 2008 so different? 3.) Frederic Kerrest @ Okta said: "it is 70% market, 20% team and 10% product", would Geoff agree with this weighting? How has his weighting changed over time? YC has "10 Minute Meetings", how can YC really determine whether someone is investable in 10 mins? How does Geoff think about the hailed VC term, "pattern matching"? Why does Geoff believe you lose as an investor if you fall back on "profiles"? 4.) Geoff has worked with 100s of founders in the idea validation stage, how does Geoff know when a founder has the right idea? How does Geoff think about the balance between mission and vision but then also being realistic about when something is not working? When do you quit? Why is the decision internal not external? What is the most important perspective any investor can give a founder? 5.) How does Geoff think about the coined term "product-market fit" and how does he analyse it in terms of retention and growth? If they have some signs of it, how should founders think about when is the right time to raise their first round? How does Geoff think about the benefits for founders of convertibles and now SAFE's? What does Geoff believe will be the future of legal round mechanics? Items Mentioned In Today’s Show: Geoff’s Fave Book: Titan: The Life of John D.
