    We invest in 2 archetypes at @cantos: 1. Full-stack deep tech selling an end product or even commodity, _not_ tech. 2. Weird n-of-1 never seen anything like it before. Selling tech to incumbents... PASS Commercializing science... PASS Nth co doing the current thing... PASS

    A freakin' startup is landing on the moon, giving us this kind of footage, and you're investing in voice agents??

    That feeling you get when you look out the window and realize you’re almost home! T-4 days until we land in the Moon. Blue Ghost will reach her final destination no earlier than 2:34 am CST on March 2. We’ll start the joint livestream with @NASA at 1:20 am CST, approximately 75

    One of my LPs, a former banker, joined a startup as CFO and is pitching VCs for the first time. He just told me, "I come away from most of these calls and I'm like 'man, who the hell gave you money??'" 💀

    Talked to a founder whose company is profitable with ARR in the $10-20M range but not it's necessarily on VC-style rocket ship trajectory. He's been taking out LBO-style debt to buy out his Seed investors at ~5x ARR. I respect the hell out of that.

    VCs, look at this table. LOOK AT IT. If you take 10yrs to return 3x net your IRR is 12%. Rn LPs can get 5% RISK FREE, & probs 7-9% w incrementally more risk if they’re savvy bond investors. Yet <10% of funds do >3x DPI. If this doesn’t scare you then you’re asleep at the wheel.

    A friend just told me about a hardware startup that struggled to raise from VCs for years and will do >$150M in top line this year at ~30% EBITDA margins. idk who needs to hear this but there’s alpha in being non-consensus.
