Solo Founders

She Built Facebook's First Assistant. Now She's Betting Against Full Autonomy | Shivani Poddar, Wajo

Shivani Poddar led engineering on Google DeepMind's autonomous coding agent. Then she went solo to build Fo — the personal agent whose viral launch admitted what no AI lab will: AI often can't finish the job alone, so her agent hires vetted humans and picks up the phone itself. A decade of building assistants at Alexa, Meta, and DeepMind, distilled into the sharpest product thesis of the agent era — plus her playbook for building a founding team without a co-founder. Topics covered: - Why every AI agent demo falls apart at the last mile ("the captcha monkey problem") - Giving an agent a phone: designing calls people don't hang up on - Seeding the product with contractors in Ohio instead of Valley insiders - Humans in the loop without a gig economy - Building the founding team: no cold hires, and a three-word recruiting message - The speed-dial bench: how solo founders augment what they're not - The bear and bull case for solo founding Guest: Shivani Poddar — solo founder of Wajo AI (maker of Fo); ex-Google DeepMind, Meta, and Alexa; backed by Vinod Khosla, Jeff Dean, and Gokul Rajaram.

No Co-Founder, a Year in Stealth and $20M to Replace Slack | Sara Du, Ando

Sara Du co-founded Alloy Automation at 19 and ran it for five and a half years. Her second company, Ando, she's building solo: team messaging designed from scratch for humans and AI agents working together, freshly out of stealth with a $20M seed from Accel, Index Ventures, and Emergence Capital.

1M Users in 3 Months, Pivoted, Then Tripled User Count | James Clift, Durable

James Clift hasn't been employed by a company he didn't own since he was sixteen. He paid for a year of university with a window-cleaning business, bought VisualCV as a $100K legacy resume site and rebuilt it (sold 2020), then went solo at South Park Commons and founded Durable, where about 3.5 million people have signed up to start or run a business, more than half of them brand new, on a six-engineer team backed by a $14M Series A led by Spark Capital. Julian and James get into the mission ("make owning a business easier than having a job"), the co-founder math that never works, why a viral AI website builder that hit a million users in three months was a distraction, what door-to-door sales teaches you about fundraising, and why everyone should make a dollar on their own at least once.

Why You Don't Need a Co-Founder to Start | Dave Morin, Offline Ventures

Dave Morin helped launch Facebook Platform, founded Path, co-founded Slow Ventures, and now runs Offline Ventures. He backed Ben Cera fifteen years before Polsia and chairs the OpenClaw Foundation. He calls himself a producer, not an investor, and makes the case that founding is a relational act: most startups fail on relationships, not product, and the only way solo founding fails is believing "solo" means alone. Topics covered: - The Alchemist, and why starting is freedom from suffering - "YouTube can be your co-founder. ChatGPT can be your co-founder." - The producer, not the investor: why startups die on relationships - What Jony Ive told Dave when Steve Jobs died - The first twelve hours with Clawdbot, and finding Peter Steinberger - How Polsia actually started: Gift Shop, Kyoto, Company OS, and "Am I crazy?" - Ramble, and the 10,000-dinners test for what to build - The bear case and the bull case for solo founding Guest: Dave Morin — co-founder of Offline Ventures (offline.vc); early Facebook, founder of Path, co-founder of Slow Ventures, Chairperson of the OpenClaw Foundation.

5 Solo Founders Called In With Their Hardest Problem | Solo Founders Office Hours

Five solo founders brought their hardest current problem to a live office hours, and Julian worked each one in real time. An open-source app with 1.25 million users and a few hundred paying subscribers. A data product the market "doesn't know it needs." A one-person vendor selling benchmarks to frontier AI labs. A wholesale-ordering startup whose customers keep asking for the wrong features. A robot company deciding whether the body or the brain comes first. The answers keep landing in the same place: they were building what they wanted to sell, not what the customer would say yes to. Topics covered: Monetizing an open-source app without losing user trust: charge for core value, not perks Services as software: why "I want to sell a product" can be the mistake Calendar spearing, and compressing every step between "I have this problem" and "yes" Going solo: customers as the orienting force, building as the addictive default (add "after a co-founder split" only with Ryan's OK) "Don't be the best, be the only" — whether buyers take a one-person company seriously Feature requests are jobs to be done: the micro-app middle path Hardware vs. software scope: ship the mind before the body Founders: Utkarsh Dalal (GameNative), Ryan Junejo (Crash Labs), Charlie Kahn (Brio), Andy (Phenomni).

About 65% of high-potential startups that fail die from co-founder conflict. Julian, who spent seven years matching co-founders before starting Solo Founders, answers the six questions people ask most about going solo: do you need a co-founder, is it as lonely as it sounds, who has actually done it, how do you raise money alone, do solo founders fail more, and what is "solo founder syndrome."

Searching For A Co-Founder Is How You Get A Bad One | 4 VC-Backed Solo Founders

It's been a year since the Solo Founders Program kicked off. Today, the first cohort sits down to discuss building solo, together. What a year of building taught them: why retention is growth (the smile curve, and the leaky bucket nobody checks), why free users are a "free trend" and not a business, how to kill a good idea to find the better one, and what a room full of other founders actually gets you. Plus the stories they lived before going solo — including co-founding with your dad at 17. Topics covered: The prerequisite trap: why searching for a co-founder gets you a bad one Co-founder failure modes: family, close friends, and misaligned incentives Finding a co-founder by building (elevating a first hire) Retention is growth: the smile curve and the leaky bucket Hype signals vs. paying customers — the 10x question Solo, together: what a founder community functionally replaces Guests: Aldo Del Valle (new company, prev. Happypath), Chai Choudhary (Workers.io), Namanyay Goel (Giga), Dhravya Shah (Supermemory)

Why PostHog's 6th Employee Went Solo | Yakko Majuri, Railcode

Companies are handing every employee AI coding tools and calling themselves AI-native — then blocking everything those employees build. Yakko Majuri, early PostHog engineer and infrastructure lead at Doublepoint through its acquisition by Oura, just launched Railcode: a secure home for internal apps and AI agents where you build with your own tools and deploy in seconds. He gives a live demo — Railcode's first on camera — and explains why most software going forward will be internal. Topics covered: The "AI-forward" illusion: giving out Claude Code isn't a strategy The one-question test: are you holding your team back? Why most software is about to go internal (and when internal tooling IS the product) The CEO who vibe codes vs. the CTO who wouldn't let him ship Joining early PostHog through the handbook: work trials, six-person teams, hackathons Finding your startup idea by pulling the thread through your old customer notes Advice for solo founders: build the thing that's an extension of you Guest: Yakko Majuri — founder of Railcode (railcode.dev), early PostHog engineer, Solo Founders Program member.

AI Can Build Your App. It Can't Make It Good. | Paul Bakaus, Impeccable

Paul Bakaus created jQuery UI, sold a startup to Zynga, and spent nearly a decade at Google — then went solo to prove one experienced builder, amplified by AI, can do what used to take a team. His company Renaissance Geek is backed by a16z; its first product, Impeccable, stops AI coding agents from shipping design slop. Topics covered: Why his first hire was a chief of staff, not an engineer (the middle-manager trap) The era of the 40-year-old founder: intuition and craftsmanship as leverage What Impeccable is and why AI design slop is a moving target Free-first distribution: no ads, no outbound, only tweets Judgment over generation: Steve Jobs as the greatest editor of all time The bear and bull case for solo founding Guest: Paul Bakaus — solo founder & CEO of Renaissance Geek (Impeccable), creator of jQuery UI, ex-Google.

What It Actually Takes To Build a Startup Solo | 6 VC-Backed Successful Solo Founders

Claire Vo runs ChatPRD — an AI "Chief Product Officer" for over 100k product managers — as the only full-time human, bootstrapped, with zero venture capital. The twist: she operates the company with a staff of nine named AI agents she manages like real employees, one of whom emailed the studio before she arrived to coordinate arrival time. She and Julian dig into how she built it, why she runs nine scoped agents instead of one, and the honest case for and against going completely solo. Topics covered: The one-person company: running a real business with a team of AI agents "Agents are just management" — scoping AI agents like employees Bootstrapping solo with zero VC, and why the model isn't the moat The "20-year overnight success" — earned expertise as the real advantage Authorship over ownership: building a business that serves your life The bear and bull case for solo founding Guest: Claire Vo — solo founder of ChatPRD (AI for product managers); former CTO of Color Health and Chief Product and Technology Officer at LaunchDarkly; host of the How I AI podcast.

Today we're launching Solo Grants: $100–$1,000 grants, 100% no strings attached, for people building technically ambitious projects solo. Julian sits down with Ari Dutilh who leads the program and is a former grantee himself, to map the wide world of microgrants and explain why the gap between a project seen through and one abandoned is usually just a few hundred dollars.

She Raised $18M Solo to Kill AI Slop | Thais Castello Branco, Taste Labs

Thais Castello Branco left the AI search company Exa, raised $18.5M, and built Taste Labs -- the "taste layer for AI" -- solo, with one mission: end AI slop. She and Julian go deep on what taste actually is (and why it isn't personalization), why everything AI makes is starting to look the same, how you turn something as subjective as "great design" into data a model can learn, and the honest case for going solo. Topics covered: Why taste is a measurable bar for quality, not just personal preference The real cause of "AI slop" — volume, not bad models How to turn a subjective domain into something a model can learn Why you're probably bad at "commissioning" AI Building a ~800-person community of tastemakers The bear and bull case for being a solo founder Guest: Thais Castello Branco, founder & CEO of Taste Labs, the "taste layer for AI" (ex-Exa).

Going Solo Should Be the Rule, Not the Exception | Flo Crivello, Lindy

His Public Company Blew Up. He Came Back Solo. | Francis Davidson, Odessia

Francis Davidson built Sonder into a multi-billion-dollar company, took it public, was pushed out as CEO, and watched it collapse. The same month he left, he started over — this time solo, building Odessia, an AI travel agent, with a founding team of seven. This is the honest version of the comeback: why he went solo when his co-founders were great, why he skipped the MVP, and why he still thinks the one-person billion-dollar company is a myth. Topics covered: - Building Sonder from a college side-hustle into a billion-dollar company, and its collapse - Why he went solo for the comeback when his co-founders were great - Skipping the MVP: how coding agents rewrote the startup playbook - Solo, not alone: building a founding team of seven with full ownership - Founder mode vs. hiring executives, the hardest lesson from Sonder Guest: Francis Davidson — founder & CEO of Odessia and previously founder & CEO of Sonder.

Sold a Company at 16, Raised $3M at 19 | Dhravya Shah, Supermemory

Dhravya Shah sold his first company at 16 and raised $3M at 19 as the solo founder of Supermemory, the open-source memory and context layer for AI agents (now past 26k GitHub stars and 1M+ SDK downloads). The twist: he never chased any of it as a business. He built in public, for free, said no to VCs for nine months, and only raised once the company's vision was undeniable. A conversation about why the fundraise is a result, not the goal. Topics covered: Why the raise is a result, not the goal — and saying no to VCs for nine months Building your "art" in public until it becomes a company Escaping the inventor's dilemma: killing your own viral hits Why he's a solo founder, after a co-founder breakup killed an earlier company The honest version of AI memory: benchmark-gaming, Goodhart's Law, and evals that matter Hiring "true builders" out of open source as a solo founder Guest: Dhravya Shah — founder and CEO of Supermemory, the memory layer for AI agents (1M+ SDK downloads); sold his first company at 16, raised $3M at 19; ASU dropout and ex-Cloudflare.

I Asked 5 Massively Successful Founders Why They Went Solo

A $300M company. 30M+ users. Tens of millions in revenue, some raised and some bootstrapped from zero. Software that saves lives. Five founders, zero co-founders. Julian connects the dots across the first six episodes of the show — Ben Cera (Polsia, $30M raised), Yasser Elsaid (Chatbase, $10M ARR bootstrapped), Paul Klein IV (Browserbase, a $300M company), Eugenia Kuyda (Replika, 30M+ users), Daniel Francis (Abel), and investor Charles Hudson (Precursor Ventures) — on why they built alone, and what they all figured out about it. The through-line: don't take a co-founder of convenience. A talented solo founder beats a mismatched team, and most co-founders get taken for the wrong reasons rather than because they're a genuine fit. Topics covered: - The "co-founder of convenience" — and why a talented solo founder beats a mismatched team - Why the human 20% (taste, judgment, direction) is the whole game - The clarity advantage: one voice, one layer of alignment - Building from the personal, because the most personal is the most universal - Mission as a forcing function — when the work clarifies every decision - True solo vs free solo: two routes to the same rejection of the co-founder default
