this is such an awesome event. over half of our partner / GP searches have been open to bringing in operators who’ve never been full-time investors. more and more firms are heading that way. two legends who’ve made the leap talking through it is rare air.

Jeff Bezos put $250k into Google’s $1M seed round. One of just four investors. Absolutely wild. Best seed investment by a sitting founder/ceo in tech history? .Amazon had just gone public. Shoutout to @AcquiredFM on a great pod 🫡.
