Max and @zhaolan_monk met during ODF's second cohort and decided to co-found Warmly. 7 years later: acquisition by HubSpot Congrats to the team!
Big news: @HubSpot (NYSE: HUBS) is acquiring @warmlyai . Well that feels surreal to write. Today, I feel just as excited as 7 years ago when I was starting up! Back then, I was giddy. Just a guy with an idea & a few cofounders hoping to change the world of GTM forever. And then reality struck - building a company was hard! Every day we learned a little more, failed a little less and 6 pivots later advances in LLMs finally unlocked the product we’d been trying to build. In 2023 we took years of battle scars building our own GTM & put everything we had into building AI Agents that would modernize how marketing & sales teams worked together. Enter HubSpot. In 2023 we built our first integration. (It was HubSpot) In 2024 we had 20 customers integrated with HubSpot In 2025 we had 100 customers integrated with HubSpot In 2026 we now have 223 paying customers integrated with HubSpot! As Warmly has grown, HubSpot has always been there for us. As Warmly’s AI Agents started booking meetings for customers, HubSpot’s Data Hub was a key source. As Warmly’s Inbound Agent enticed & de-anonymized website visitors, HubSpot’s Smart CRM was where we stored chat transcripts. As Warmly’s TAM Agent created differentiated fresh lead lists, HubSpot’s dashboards showed GTM Execs how much pipeline we got them. And today, we’re joining forces to build the future of AI-native GTM and help our customers grow their business with both Warmth and HEART (if you know, you know). So what happens next? 1/ To our customers: this is just the beginning. Thank you for taking a bet on us and making us into the business we are today. Stay tuned for more epic releases coming soon. 2/ To our Warmsters past and present: Every feature shipped, every customer won, every late night, every hard conversation, this company exists because you always exhibited our core value to always Add A Comma, in everything you do. 3/ To my cofounders new and old: @zhaolan_monk @carinaboo, Val @KeeganOtter7, Ryan - You’re my best friends, the reason I can tackle every curveball that was thrown our way. We’ve climbed mountains and persevered. Thank you. 4/ To our new teammates: Angela, Richa, Jared, Duncan, Yamini - we are stepping on the shoulders of giants. Can’t wait to build amazing AI-native solutions to 10x our customers! 5/ To me: 7 years ago you would have never believed you’d be here today, be proud. I only hope for you that, 7 years from now, you will continue to surprise yourself on what you can accomplish. Signing off as we always have, but this time with more excitement than ever. Warmly, Max

Solo founding will become the default. We’re building the infrastructure to improve each solo founder’s likelihood of success. Thanks Barron’s for the conversation.

If you're the one communicating and the person on the other end doesn't understand you, that's your fault. Julian Weisser (@julianweisser), who ran 27 founder cohorts at ODF (@joinodf) and now hosts his own founder interviews, says he never reviews conversations after the fact, even though transcription and video make that possible now. He credits Richard Feynman's idea that if you truly understand something, you can explain it to anyone from a four-year-old to an eighty-four-year-old. "You can tell by somebody's facial expression: do they get it, do they not get it." Full episode:piped.video/7ku8WVvAmyc?si=m_5U…
New pod drop! Full circle - I met Julian (@julianweisser) almost 10 years ago in ODF 1 (~100 people, in person in SF). They’re on cohort 27 now, wild! He also recently launched Solo Founders (@solofounders) - we love to see it! We cover: - From Jazz to startups: let people play their own instruments - Giving early employees high equity - Co-founders aren’t forever — they have seasons - “If they don’t get it, that’s your fault” - Music school → On Deck → Solo Founders - Biggest risk isn’t dilution. It’s co-founder conflict - Life philosophy: keep going so much more! Timestamps (00:00) Trailer (00:51) Julian Weisser, Founder, Solo Founders (02:06) Calling his old jazz taste "musical masturbation" (20:17) 27 cohorts, thousands of founders, more reps than any VC (35:50) The $400K co-founder payout demand (39:45) The Hacker News post that led to Dropbox's first employee (44:45) Golden Gate Park was built from sand dunes (54:50) Why co-founders have seasons, not forever contracts (58:53) The "oddballs" who never wanted co-founders, including Loyal's Celine Halioua (1:00:59) Co-founders are the car phone. Solo founders are the cell phone. (1:06:47) Why owning less equity can mean more freedom (1:16:18) His two-word life philosophy: keep going (1:16:34) Outro Link - piped.video/7ku8WVvAmyc

Be the only. 24:13 Charlie Kahn - the features they ask for vs. the brain they don't 28:28 They're asking for jobs to be done 36:06 Andy Wang - a second pair of hands, or don't split your time? 39:37 Ship the mind before the body

The wrong co-founder leaves you 50% as good as you could be. @FounderLaberge never had a co-founder. Instead, he taught himself spectroscopy and raised $41.5M to put sensors inside Al data centers (at 20). Solo Founders Podcast ep 25 is live with Zach Laberge of @TryOmenAI. 16:51 Shutting down his first company at 18 22:05 $3M raised in three days 26:11 Engines don't break - hydraulics do 33:51 "You're an idiot": six months early on data centers 37:55 Solo by default 45:13 The greatest fundraising market in history 52:58 The bear case for solo founding 59:05 Why no co-founder made him 10x better

Big news for Preview! Congrats @fejes713 and crew!
Preview has raised $12M in funding to date, led by @sequoia with participation from @thegp and @farooqib. AI video is now part of how real productions get made. What professional work requires hasn't changed: scripts, shot lists, versions, reviews, deliveries, and a clear record of how every frame was made. Preview is the professional platform where AI video production runs. Producers, directors, and artists planning, generating, reviewing, and delivering together, from first idea to editor handover. Studios already run real work on Preview: commercial productions for Fortune 100 brands, and some of the first hybrid films with Oscar-winning talent, arriving on streaming platforms later this year. 3,000 studios are on the waitlist. We're letting the next ones in now.

Impossible to overstate how foundational Peter is to the startup ecosystem. His ability to start and contextualize important discussions has done tremendous good. Peter: proud to partner with you across ODF and Solo Founders. Love reading all of the congratulatory tweets.
Life update - last day here at Carta. Building insights on startups and venture has been the most intellectually engaging work I've ever done. What a freaking blast. Up next - headed to @OpenRouter to tell data stories about AI and learn from some ridiculously smart ppl 🙏
