I've started saying no to more and more interviews. a/ I don't like to hear myself talk. I'm dumb enough as it is. b/ Most podcast hosts aren't thoughtful and as such don't ask thoughtful questions But @Magyer isn't that. Love all the thoughtful q's and thanks for having me on
Excited to share my conversation with @cupazhou of @SuperclustersLP. We talked about picking VCs, emerging managers, portfolio construction, and which of sourcing, picking, and winning is the most important. Here are the longer notes and takeaways from this episode of

We’re proud investors in @trytrata. The product is fantastic, which I’m pretty aware of having been a buyer, seller, creator, and user of investment research. Highly recommend public investors give @trytrata a try!

Earlier this year, 24 year-old @aliniikk was running an AI recruiting startup. @micro1_ai pivoted into AI training, and in 8 months the company is now making $100 million a year, and fielding offers at a $2.5 billion valuation. https://t.co/Us7BjiikG5

@conor_ai @hyperspell I talked to a VC this morning who has a few portfolio companies that are @hyperspell customers. Pretty great proof point about Hyperspell’s ability to help AI agents do better work and for builders to get to market sooner.

This discussion with Joe was terrific. Watching Joe apply his craft to early-stage companies at @SeaplaneVC is a real treat. We cover: * Unit economics of early stage companies * Using AI as a research analyst * Public v private investor economics * Joe’s research process *
Excited to share my take about early-stage investing, unit economics, and AI with @OwenRask on his podcast. This was my 4th time (!) on Owen's show over the years and every time is a fun, nerdy conversation. Hope you enjoy! https://t.co/Pkm8XBLVlp

@Magyer @aliniikk @micro1_ai @SeaplaneVC Incredible trajectory for @aliniikk and the team. And a massive well done to you, Joe, for identifying that, and supporting the business early days. Seems a big win-win-win.
