  1. The Secret $2 Trillion Market Founders Are Ignoring | Sunil Rajaraman, Hamlet

    6D AGO

    The Secret $2 Trillion Market Founders Are Ignoring | Sunil Rajaraman, Hamlet

    Two trillion dollars of GDP flows through local government every year. 90%+ of city council votes are pre-decided before the meeting starts. And almost no founder will touch the market. Sunil is the rare exception. He ran for city council in Orinda, California, lost, and walked away with a newsletter for residents and an obsession with how opaque local government actually is. That newsletter became Hamlet — the civic AI making local government meetings legible to residents, real estate developers, and the cities themselves. This episode is the most concrete civic-engagement segment we've recorded on the show, and incidentally a clean founder thesis on how to spot a market everyone else is ignoring. Topics covered: $2 trillion of GDP runs through local government — and almost no founder will touch it90%+ of city council votes are pre-decided before the meeting startsWhy "public comment is largely ineffective" and why the "local vocals" aren't representativeMost city councils are rubber-stamp organizationsRunning for Orinda city council — and the $20K-minimum reality of nominally non-partisan local electionsThe civic-engagement on-ramp — join a commission as the lowest-friction way to start participatingThe newsletter-MVP-to-Hamlet arc — how a personal newsletter for residents became a civic AI companyEasy-to-explain businesses and why they require context, knowledge, and subject-matter expertise (the Federer analogy)"If you don't have an original insight, just don't work on it" — Sunil's hardest founder filter"No one's going to care about this problem as much as me" — niche obsession as the only test that mattersThe Bold Italic acquisition, "This Is Your Life in Silicon Valley," and why you can't copy editorial voiceFront-loaded advisor relationships as a substitute for the co-founder dynamicPricing humility — "C-minus, D-plus" — and what to do about itBear case for solo founding — resentment, no gut-check, easier to fractureThe "let things simmer" leadership ruleBull case for solo founding — "consensus produces average outcomes"Guest: Sunil — Founder and CEO, Hamlet. Previously co-founder of Scripted (Crosslink, Redpoint), EIR at Foundation Capital, executive at GoodRx through its IPO. Ran for Orinda city council. Crosslink-backed twice across 15 years and 2 companies. Host: Julian Weisser — Founder/CEO of Solo Founders and Co-Founder/CEO of On Deck/ODF.

    Do You Really Need A Co-Founder? With Julian Weisser (Solo Founders)

    For the first time ever, more than one in three new companies are being started solo. Five years ago that number was under 25%. This week the host becomes the guest: Julian Weisser — founder of Solo Founders, former co-founder of On Deck (where he ran 27 ODF cohorts and helped over 1,000 founders collectively raise $2B+) — sits down with David J. Phillips (CEO of Fondo, solo founder) for the full thesis behind Solo Founders. They cover the "denominator delusion" that keeps the co-founder default alive, the three types of solo founders (True Solo, Free Solo, Juiced Solo), why companies run out of hope long before they run out of money, and the bear and bull case for going it alone. Plus the news: the next Solo Founders cohort will include $100,000 per solo founder. Topics covered: Denominator delusion — why "the most successful startups have co-founders" ignores the failure rateThe co-founder of convenience trap1 in 3 companies are now solo-founded (up from under 25% five years ago) — the Carta data$100K per solo founder — the new Solo Founders Program cohort newsWhy Solo Founders doesn't run a Demo Day — the factory model critiqueTrue Solo / Free Solo / Juiced Solo — Julian's new three-type taxonomy with named examplesWhy companies run out of hope long before they run out of money"The median company is a dead company" and "the average VC is a walking-dead VC"Bear case for solo founding — the co-founder-shaped hole and playing on hard modeBull case for solo founding — one point of failure, one point of resilience, and "the company only dies if you do"Solo alone vs solo together — the Solo Founders Program thesis in one lineStartups as art and the case against "contortionism"Guest: Julian Weisser — Founder, Solo Founders.

    Rahul Sonwalker is the solo founder and CEO of Julius AI — the natural-language data analysis platform that took six pivots (and one cease-and-desist from Microsoft for calling a product "Excel Copilot") to find. In this conversation, Rahul breaks down the "co-founder trap" that keeps most smart people stuck searching instead of building, why every great startup violates 1–2 core best practices, and why he insists on being the worst coder on his own team.

    $9M ARR, Zero Investors: Yasser Elsaid on Bootstrapping Chatbase as a Solo Founder

    Yasser Elsaid was in his last semester of university when he spotted an opportunity most people dismissed: adding custom data to large language models, before ChatGPT even launched. He built the first version of Chatbase in six weeks, got his first Stripe payment 30 minutes after launch, and has bootstrapped to $9M ARR over three years with zero outside funding. In this conversation, he breaks down the counterintuitive playbook behind his success — from the "benevolent dictatorship" of solo founding to why margins don't matter early on. Topics covered:- Spotting the RAG opportunity before ChatGPT launched and building in six weeks- First Stripe payment 30 minutes after putting up a pricing page- Why first principles thinking beats market research in paradigm shifts- Deciding to go solo — skipping the pitch deck, investors, and co-founder search- "Free solo" founding — bootstrapping beyond the indie hacker lifestyle business- The benevolent dictatorship: why solo founders make faster decisions- Low-ego decision-making — changing your mind is a feature, not a bug- Two-way door decisions and the Bezos framework for AI startups- Scaling a bootstrapped company: profitability from day one, then spending aggressively- Recruiting at a bootstrapped company vs. VC-backed — why bootstrapped equity is less risky- The B2B playbook: self-serve plus sales layer, content as the foundation- Pricing is the fastest lever — no science, just experimentation- Margins don't matter early on — revenue signals compound, cost savings don't- Bear case and bull case for solo founding Guest: Yasser Elsaid — Solo Founder and CEO, Chatbase. AI-powered customer service platform. $9M ARR, bootstrapped, 30-person team. Based in Toronto. Previously built side projects at York University. Former intern at Meta, Tesla, BlackBerry.

    Daniel Francis dropped out of high school, taught himself to code at a DC nonprofit, impersonated a laid-off Twitter employee to work for Elon Musk, and then built Abel Police — AI software that generates police reports from body cam footage, saving officers a third of their shift from paperwork. In this conversation, he shares the personal experience that led him to policing, why he believes solo founders have a massive authorship advantage, and his unfiltered take on co-founders, culture, and the emotional reality of building alone.
