Jonathan Siegel is mentioned in the article (his company acquired Baremetrics). I dealt with Jonathan in the past, and I could only say good things about him - not just his business acumen, but his integrity and generosity.
Years ago Jonathan was in a position where we needed to buy back his shares in a company in which he invested early. He could have asked for a much higher price, and instead he graciously agreed to a different outcome - he understood the situation and did the right thing.
Glad to see that General Catalyst did the same in relation to Baremetrics, writing off their investment. These things don't go unnoticed. Sometimes reputation is way more important than a few more bucks for your LPs.
