    Every time I get to see the @sequoia process I’m reminded of what “great” looks like. The truth it isn’t complicated. Some notes: 1. Make the calls you say you will 2. Schedule the meetings you say you will on time 3. If you ask for the data room, actually look at the data room

    It is much easier to advise 1000 companies than build 1.

    If a "pre-seed" is 1.5m on 10, and a "seed" is 5-7 on 20-30, can we all just agree to hit "reset" and go back to "seed" and "Series A"?

    After a year back at operating, I'm realizing that most of the specific operating advice I gave founders in my last few years at YC was...stale.

    Jewish friends in Brooklyn are being told to avoid going into the street on Saturday because of a "Flood Brooklyn for Gaza" protest. In 2023. In America. In Brooklyn. Here's a thought @ericadamsfornyc and @NYPDCT - stop the dangerous protest instead of telling Jews to hide in

    It has become terrifyingly clear to me that everyone I look up to is making it up as they go along.

    Zuck is doing a great job demonstrating that cash and liquid stock can be a hell of a lot more compelling than paper valuations and infrequent tenders.

    The strongest predictor of founder success may just be a willingness to look stupid.

    The losers in the IPO drought are employees – not investors who have other bets and management fees and not founders who can get loans and secondaries. The basic agreement at the heart of “going to work at a startup” is broken.
