Solo Founders

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."

Topics covered:
- Solo founder vs co-founder: raise the bar; don't settle for a co-founder of convenience
- Why ~65% of startup failures trace to the founding team, and what that means if you're solo
- Loneliness as the solo founder's real failure mode, and "solo, together" as the fix
- Famous solo founders past and present: eBay, Dell, Zoom, Browserbase, WorkOS, Loyal, Polsia
- Fundraising alone: the pass as an easy out; investors reading your talent bar through your hires
- The dilution advantage: optimizing for investor quality over valuation
- The denominator delusion: the base-rate error behind "solo founders fail more"
- "Solo founder syndrome," debunked

Host: Julian Weisser, founder of Solo Founders; previously co-founded On Deck (ODF), where he ran the largest co-founder-matching program in tech for seven years.

Zach Laberge dropped out of high school to build his first company. His second, Omen AI, puts real-time sensors inside the fluids that keep AI data centers and industrial machines running. He's 20, has no co-founder, and has raised $41.5M. He explains why having no technical co-founder forced him to learn spectroscopy himself, and why that made him better.

Topics covered:
- The shutdown test: how to know when to stop, and how to wind down well
- Restarting from your strengths: $3M raised in three days from the buyers who'd said no
- Customer-led pivots: engines to hydraulics to AI data-center coolant
- Being six months early, and the bitcoin miner who laughed
- Founding teams without co-founders; resetting the team at the seed
- Fundraising in a concentrated market: "the best round is when you're not raising"
- Advisors: weekly 1:1s and templated equity
- The bear case and the bull case for solo founding

Guest: Zach Laberge — founder & CEO of Omen AI (omen.ai), real-time fluid intelligence for AI data centers and industrial machines.

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)

John Glasgow is the anti-pattern founder: non-technical, 36 when he started, a newborn at home during Y Combinator, and solo after his co-founder left within weeks. After 15 years in corporate finance at Adobe, Fidelity, and Invoice2go, he built Campfire, the AI-native ERP fast-growing companies use to replace legacy systems. This is one of the most tactical conversations we've recorded.

Topics covered:

• The "right to win" filter: which ideas deserve your resignation letter
• The enterprise sales playbook from the buyer's side: champions, the $95K threshold tactic, budget cycles
• Surviving two years pre-product-market fit as a solo founder
• Founding at 36 with kids, and why deferring life causes burnout
• Why the technical co-founder requirement is over in the AI era

Guest: John Glasgow — founder & CEO of Campfire (campfire.ai), the AI-native ERP.

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.

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.

Everyone thinks going solo means answering to no one. Six solo founders behind WorkOS, Fondo, Plug, Lighthouse, Hamlet, and Julius AI say the opposite: you have more bosses, not fewer, and the job is convincing all of them. Julian revisits the six moments that deserved more attention the first time around.

Topics covered:
- Why going solo means more convincing, not less (Rahul Sonwalkar, Julius AI)
- The original-insight test: "if you don't have one, don't start" (Sunil Rajaraman, Hamlet)
- The "wrong" business model behind a 16-to-429 hockey stick (Jimmy Douglas, Plug)
- The $40,000 filter that picked David Phillips' company for him (Fondo)
- How services scale like software now (Minn Kim, Lighthouse)
- Why sales is the one job a founder should never hand off early (Michael Grinich, WorkOS)

Featuring clips from Julian's conversations with all six founders. Full episodes at solofounders.com and on the Solo Founders YouTube channel.

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.

Topics covered:

• The Solo Grants launch: $100 to $1,000, no equity, no payback, and it doesn't have to be a business
• Microgrants 101: 1517's $1,000 checks, Emergent Ventures, and the Thiel Fellowship lineage
• The grantee who asked for $100 less than his application, and the three viruses he went on to discover and name
• Why first-time builders never even look for co-founders
• Ari's path from a $500 high school grant to running the program
• The funder who said "be more ambitious" and gave more than he asked for
• How to apply, and the directory that routes you to the right grant program

Guest: Ari Dutilh — running Solo Grants (formerly Merge) and producer of the Solo Founders Podcast.

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).
