Today, I’m proud to announce @DayOneVC’s $150M fund III that brings our AUM to over $450M. Our north star remains the same: we will keep betting on the most exceptional founders of our time working on the biggest ideas possible.

$525M in financing for @praxisnation to build the next great city. Together with our partners, we designed a novel drawdown mechanism for the development of new cities. This is its first deployment.

Excited to announce Abel had just raised $5m from some of the best investors on earth. Get in gang we are going to save American cities. techcrunch.com/2024/10/17/fr…

The diamond drill rig for mineral exploration was first tested in Minnesota in 1890 and hasn't seen a fundamental innovation since 1953. We @durinmining built a remotely operable drill rig in 4 months. Our next version will be autonomous. Testing begins in Nevada next week.

Better health is better business. Today we’re launching the Founder Health Coalition — a movement for founders, investors, and startup leaders who believe that peak performance starts with peak health 👇

WE ARE READY TO FLY! This was the last gate needed to launch Odin. Can't wait to strap this thing the side of the falcon and send it to the cosmos. Thanks to @payloadspace and @TimFernholz for the write-up!

Introducing Showrunner: the Netflix of AI From our South Park AI experiment to today we’ve believed AI movies/shows are a playable medium. We just raised a round from Amazon & more and the Alpha is live today Comment for an access code to make with all our shows.

New Core Memory episode on the future of babies

Exciting news from @OrchidInc! Today, we're announcing the world's first whole genome embryo reports. This is a massive upgrade – 100x the amount of data – and a major leap in reproductive tech. And the best part, it's now available at IVF centers across the nation.

Introducing Kids Model 123 – comfortable & durable, made with a redesigned outsole that flexes with every movement. This has become a personal project for us, as we set out to make the best shoes that our kids will love wearing everyday! atoms.com/model123

1/ A future where we can support millions of people living on the Moon or Mars is far more exciting than one where that possibility doesn’t exist. Today, @StarpathSpace is announcing over $11M in total funding to help make that multi-planet future a reality

I've spent years wanting to build a consumer app that was impossible for a long time. Now the tech has finally caught up to my vision. Introducing SocialAI, a private social network where you receive millions of AI-generated comments offering feedback, advice & reflections on each post you make. SocialAI is more than just another project for me – it’s the culmination of everything I’ve been thinking about, obsessing over, and dreaming of for years. I’ve always wanted to create something that not only showcases what’s possible with tech but also helps people in a real, tangible way. SocialAI is designed to help people feel heard, and to give them a space for reflection, support, and feedback that acts like a close-knit community. This app is a little piece of me – my frustrations, my ambitions, my hopes, and everything I believe in. It’s a response to all those times I’ve felt isolated, or like I needed a sounding board but didn’t have one. I know this app won’t solve all of life’s problems, but I hope it can be a small tool for others to reflect, to grow, and to feel seen. Thank you to my family and all of my friends who have helped me through it all. I hope this app can be something special for others, just like it has been to me. ❤️

🌹 𝗪𝗲 𝗿𝗮𝗶𝘀𝗲𝗱 $𝟲𝗠 𝘁𝗼 𝘀𝗰𝗮𝗹𝗲 𝘁𝗵𝗲 𝘄𝗼𝗿𝗹𝗱’𝘀 𝗹𝗲𝗮𝗱𝗶𝗻𝗴 𝗔𝗜 𝗷𝗼𝘂𝗿𝗻𝗮𝗹 Five years ago, @seandadashi and I realized the attention economy was doing more harm than good—keeping kids and adults glued to screens, chasing dopamine. As technologists, we felt a personal responsibility to build something healthier and nourishing. After experimenting with mindful social apps—and taking a wrong turn into NFTs—we returned to our core mission: 𝘁𝗼 𝗰𝗿𝗲𝗮𝘁𝗲 𝗮 𝗺𝗼𝗿𝗲 𝗰𝗼𝗻𝘀𝗰𝗶𝗼𝘂𝘀, 𝗰𝗼𝗺𝗽𝗮𝘀𝘀𝗶𝗼𝗻𝗮𝘁𝗲, 𝗮𝗻𝗱 𝗰𝗼𝗹𝗹𝗮𝗯𝗼𝗿𝗮𝘁𝗶𝘃𝗲 𝘄𝗼𝗿𝗹𝗱. That mission came to life in @joinrosebud—an AI journal designed with therapists to help people slow down, reflect deeply, and grow. It remembers what matters and reflects it back when you’re ready to hear it. 𝗢𝘂𝗿 𝗷𝗼𝘂𝗿𝗻𝗲𝘆 𝘁𝗼 𝗽𝗿𝗼𝗱𝘂𝗰𝘁‐𝗺𝗮𝗿𝗸𝗲𝘁 𝗳𝗶𝘁 • Launched in July 2023 with a lean team and limited capital • Embraced hypothesis-driven development and counted every penny • Reached profitability in 18 months with 100K+ signups 𝗪𝗵𝗲𝗿𝗲 𝘄𝗲 𝗮𝗿𝗲 𝘁𝗼𝗱𝗮𝘆 • 8,000+ paying customers • 500 million words journaled • 30 million mindful minutes logged • 75% of users report mental health improvements in 30 days 𝗪𝗵𝘆 𝘄𝗲 𝗿𝗮𝗶𝘀𝗲𝗱 Led by @BessemerVP with participation from @Initialized, @sevensevensix, @FuelCapital, @avenirgrowth, @tferriss, and other strategic partners—this $6M round will help us: • Expand our product and engineering team • Accelerate expansion with our new Head of Growth, @growwitharjun • Deepen partnerships with therapists and coaches • Scale our purpose-built memory engine for personal growth "Mental health support shouldn't be bound by time, place, or privilege. Rosebud is leading the charge in combining AI with long-term memory to become a trusted companion in your pocket." – Maha Malik, Investor at Bessemer Venture Partners 𝗥𝗲𝗮𝗹 𝗶𝗺𝗽𝗮𝗰𝘁 “When I couldn’t trust my perceptions in my relationship, Rosebud’s memory of my past entries validated my feelings—and helped me trust myself again.” — Rosebud user, domestic violence survivor 𝗦𝗼𝗺𝗲𝘁𝗶𝗺𝗲𝘀, 𝗯𝗲𝗶𝗻𝗴 𝗵𝗲𝗮𝗿𝗱 𝗶𝘀 𝗮𝗹𝗹 𝗶𝘁 𝘁𝗮𝗸𝗲𝘀 𝘁𝗼 𝗳𝗲𝗲𝗹 𝘄𝗵𝗼𝗹𝗲 𝗮𝗴𝗮𝗶𝗻. We’re humbled by how far we’ve come and energized by what’s ahead. If you’re passionate about mental health tech, we’re hiring in LA!

After it took days to book an HVAC appointment in the sweltering heat, I built @Netic_AI: the AI revenue engine for businesses that keep America running. Silicon Valley ignored essential services for too long, so we raised $20m from @foundersfund, @greylock, @mavolpi to fix it.

We decided to help tax pros actually enjoy tax season. Not survive it. Not dread it. Enjoy it A crazy idea? Maybe Until it worked 👇

We’re officially a YOUnicorn! 🦄 Excited to share that @youdotcom just raised $100M Series C at a $1.5B valuation, led by @CoxEnterprises. We’ve been heads down building the search infrastructure for the AI and agent future. Soon there will be more AI agents using the web than humans, but today's search wasn't built for this. Agents need deep, contextual information from both public web and internal private data to make real decisions. Our web search API delivers the most up-to-date, accurate, and fastest search results for LLMs and agents. Real benchmarks show we consistently outperform the competition on accuracy and speed while staying cost-effective. Today, we’re answering over 1 billion queries every month across enterprises like DuckDuckGo, Windsurf, Harvey, and many others. There is no other startup of recent years at this scale. Grateful to our wonderful employees, customers, partners, and investors who believe in our vision. The agentic era is here - let's build it together. Try our LLM search APIs.

Some news - We're excited to announce that @HotshotSupport has been acquired by @xAI 🚀 Over the past 2 years we've built 3 video foundation models as a small team - Hotshot-XL, Hotshot Act One, and Hotshot. Training these models has given us a look into how global education, entertainment, communication, and productivity are about to change in the coming years. We're excited to continue scaling these efforts on the largest cluster in the world, Colossus, as a part of xAI! A big incredible thank you to all our teammates, investors (@shanaglick, @alexisohanian, @lachygroom, @svangel, @asilverschotz +++), and customers for coming on this journey with us. Most of all - extremely extremely grateful to know and work with @johnmullan87 . John is the best co-founder, engineer, optimist, and friend I’ve ever met and I feel very lucky everyday that I get to work alongside him. An exciting future is on the way. We’re stoked to drive there with @xAI (and work with @chaitualuru again!). We can’t wait to show you what’s coming next 💫

"The Internet will inevitably need some kind of proof-of-humanity system in the near future."

1/ Excited to announce: @epochbio has raised $18.3M Series A to scale our enzymatic technology that converts plastic waste into new materials. We're on a mission to solve plastic waste through biology. The problem is as plain as the shirt on your back: 64% of our clothes are synthetic textiles, AKA plastics.

New: I obtained the merger docs for Truepill and learned all sorts of quirky things. Not in the docs? A previous acquisition offer that fell through by one of the largest stakeholders, who seems to have stayed manifesting! Read more in Dealmaker theinformation.com/articles/…

1/6 70% of acquisitions fail due to inadequate corporate diligence. Lawyers spend months buried under thousands of documents. We’ve built an AI platform that turns months of manual review into minutes, giving dealmakers visibility into critical risks on day one, not week six.

Thrilled so share that we raised a $9M in Series A funding for @Winnie to bring high-quality child care and early education to EVERY family businessinsider.com/childcar…
