Great connecting with so many founders and investors at last week's Founders & Funders VC Reverse Pitch event in Los Angeles. Our Principal, Ben Kahan, represented 1752vc alongside an outstanding group of investors, sharing what we look for and meeting founders building across AI, CPG, fintech, and beyond. A big thank you to Jeff Erickson, Adam Shaw, and the Founders & Funders team for organizing such a great event. We had some fantastic conversations, met a lot of sharp founders, and are excited to continue connecting with companies building the future. Jiyoung Jeong of @WonderVentures, Katie Quilligan of @BankTechVC, Neal Bloom of @RisingTidePtr, Marshall Smith of Steamwork Ventures. Looking forward to the next one ๐Ÿš€

For a while, @RisingTidePtr mostly lived inside my head. That doesn't scale. This summer we stopped assigning tasks & started assigning ownership. Each team member owns a funnel: โ†’ LPs โ†’ VCs โ†’ Portfolio โ†’ Community โ†’ Investments Building systems > building dependencies.

Helion energy is building what will be the worldโ€™s first commercial fusion power plant, scheduled to be finished in 3 years. Great interview by Lex Fridman with David Kirtley (CEO of Helion). Most power plants are heat engines. You burn fuel or run fission, boil water, spin a turbine, and get about 35% electricity while the rest leaves as waste heat. Helion flips the flow. The fusion reaction makes charged particles that push back on a magnetic field tied to a capacitor bank, so you get direct electricity instead of a steam loop. That path can reach about 85% efficiency from fusion energy to electrical output, which means less conversion gear and tighter control over power delivery. ๐Ÿงช How the machine works A giant capacitor bank drives coils that both accelerate and squeeze plasma. Two plasmas, deuterium plus heliumโ€‘3, are launched from opposite sides and collide in the center. By rapidly reversing the magnetic field in about 1 microsecond, the plasma self-organizes into a fieldโ€‘reversed configuration that traps itself. Then the machine compresses it hard. Fusion happens, new charged particles appear, and their pressure pushes the magnetic field so the system dumps energy back into the capacitors. It is pulsed, up to 100Hz in tests, so each shot is a clean measure of input versus recovered electricity. ๐Ÿ›ก๏ธ Safety and waste There is no chain reaction. The device only holds about 1 second of fuel at any time, so stopping the drive stops fusion. Xโ€‘rays and some neutrons exist during operation, so you use shielding and standard controls, similar to particleโ€‘accelerator facilities. When the pulse stops, the radiation source stops. ๐Ÿ–ฅ๏ธ Why data centers care The output is highโ€‘voltage DC sitting on capacitors. You can invert to AC for the grid, or route DC with fewer conversions into rectifier buses for racks. That cuts losses and simplifies backup. The company is targeting 2028 for a first grid-tied plant for a large buyer, which lines up with growing AI power needs. ๐Ÿงฉ What is still hard Heliumโ€‘3 is scarce on Earth, so you must produce it or source it. This fuel also likes higher temperatures, roughly 200M-300M degrees, so the pulsed magnets and power electronics must be very fast and very tough. Stability is managed by giving the plasma enough โ€œspinโ€ and length so it behaves like a fast top that stays upright, plus thousands of synchronized switches that fire with microsecond timing. If this architecture keeps showing pulse gain and highโ€‘efficiency recovery, you get a compact generator that skips steam, feeds a capacitor, and delivers clean power in the exact format modern compute wants.
Here's my conversation with David Kirtley (@dkirtley), a nuclear fusion engineer, all about the physics and engineering of nuclear fission, fusion, and the future of energy. David is leading a team that's working to build the world's first commercial fusion power plant by 2028. This was a super technical conversation and a fascinating one, for both the near-term and the long-term future of human civilization.

We grew to $1B ARR faster than Stripe, Salesforce, and Palantir, while being 100% remote This was a combination of a lot of luck, focus and an excellent team Looking back, I can our team's success boils down some key principles I'm sharing in a 700-word long post: I hope that it will help every startup as much as it helped us: 1. Everything is sales. Recruiting is sales. Fundraising is sales. Retaining your best talent is sales. Dating is sales. And sales is sales. A founderโ€™s effectiveness = (technical skill ร— ability to sell). 2. You need to be in the details. The best founders can zoom all the way in and out. If someone tells you to โ€œscale yourselfโ€ by pulling back too early - theyโ€™re wrong. Being in the details is important to understand what org structure best fits your company's goals. Every 'in the weeds' founder designs their org structure from first principles. Jensen: 40 direct reports, Elon: Engineers in charge of everything, Jobs: Creative Dictatorship with Directly Responsible Individuals. Zuck: The first growth-hacking team with @chamath Founders not in the details forget what makes their products great and eventually recede into designing a standard org with standard departments which lead to standard results. 3. Your company's fate is 70% sealed by the first 20 hires Ben Horowitz: "I got this advice like 27 times. They said 'Look, here's the key: Hire A players:' and I was like ok yeah, my plan was to hire a bunch of morons but now I'm going to hire A players" The hard part isnโ€™t intent, itโ€™s judgment. The problem is you can't spot a top 1% engineer if you're not a top 10% engineer yourself. This applies to everything. Your definition of great is just what you've seen. Founders have some blind spots. Technical founders usually build bad marketing orgs. Sales-focused founders sometimes build mediocre product teams. You need the right eyes to be able to spot genius. Ego aside, bring on a technical expert and have them vet talent for you. Your first hires are your culture, your standard, your work environment. They are the company. Get the first 20 hires right. 4. Live with your customers. You canโ€™t know whatโ€™s working if youโ€™re not talking to them - all the time. Be where they are: WhatsApp, calls, DMs, in person. The closer you are to customers, the fewer mistakes you make. "The customer is the boss. They can fire everybody by choosing to spend their money elsewhere." - Sam Walton 5. Be extremely responsive. If I reply in 30 seconds, what usually takes a day gets done in hours. What takes hours gets done now. Speed compounds. 6. Your TAM is limited by your imagination, not by the market. Constantly rethink the pod, find other big issues that need solving and are valuable, and solve them exceptionally well. We went from contracts ($100M) to Employer of Record ($300M) to Payroll ($200M). Each 3x'd the TAM. 7. Never run out of cash. The only way a business dies is by running out of cash. Profitability = power. You call the shots, not investors. You can always act in the company's long-term interest because you know you are safe. We reached Series A after spending <10% of our seed. We have been profitable for the last 3 years. Cash discipline buys freedom. 8. Over-index on angels early. Angels are your best shot at making important people care - when it matters. They might not be involved day to day, but when you really need help, theyโ€™ll show up. If you don't know how to solve a problem, you should know at least a person who knows the person who can. Pick the right ones, and time your asks well. 9. There's always something out there that can kill your company. Your job is to de-risk the company. Capital, talent, and products are all a small part of a larger effort to de-risk your startup and build an enduring business. Covid-induced work from home grew our payroll and EOR business. And it seemed like RTO might kill it. But we were prepared. If you worry, you won't have to worry. 10. Stay focused. Fundraises, competitors, headlines - all noise. Focus on your customers. Focus on your product. Keep executing. In the long run, the most relentless team wins. 11. Trust your instinct. If something feels off - it probably is. Dig deeper. Courage in your convictions matters, especially as the team grows. Donโ€™t let โ€œperformative democracyโ€ slow you down. As long as youโ€™re in the seat, lead decisively - and unapologetically.
