Solo Founders

Flo Crivello raised about $50M as a solo founder, then watched the market kill the company he'd built. Instead of quitting, he cut deep, pivoted, and rebuilt alone into Lindy — one of the top AI agent startups. This is a clear-eyed playbook on knowing when to kill a company, beating burnout with momentum, and building solo without being alone.

Topics covered:

• Raising ~$50M as a solo founder
• Knowing when to kill a company and how deep to cut
• Why momentum, not rest, is the cure for burnout
• Prospecting for gold vs. operating the mine: where a founder should spend their time
• The solo founder's "brain trust": building support without a co-founder

Guest: Flo Crivello — founder & CEO of Lindy.

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.

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.

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

Michael Grinich built WorkOS solo — now a $2B company and the enterprise infrastructure behind OpenAI, Anthropic, and Replit — with no co-founder. So when he says "it's not the blood bond it was made out to be," it lands. This conversation is his case against the ride-or-die co-founder myth, the question he thinks actually matters before you start a company, and the honest bear and bull case for going it alone.

Topics covered:

• Why co-founders aren't a blood bond — and "are you the one who holds it forever?"
• The founder "mental disorder," and why you only need one person who has it
• The bear and bull case for solo founding — from John Lennon to "the company is a mirror"
• How to pick the idea: a notebook, four filters, and lessons borrowed from stand-up comedy
• Why "pivots are the most traumatic thing you can do to a business"
• The case for founder-led sales — and hiring a head of sales as a partner, not a handoff

Guest: Michael Grinich — solo founder and CEO of WorkOS, the infrastructure that makes startups enterprise-ready.

Minn Kim runs Lighthouse, the AI-powered immigration firm rebuilding the visa stack for frontier-tech companies. She is solo. She isn't a lawyer. Her first two hires were engineers. The conversation with Julian covers how she got there, why "solve your own problem" isn't always the path to success, the complicated-vs-complex framework she uses to pick what to build, and her bull case for solo founding stated as a fact about her own life rather than a thesis.

Topics covered:

• The Korean-immigrant origin and the 2022 side quest that became Lighthouse
• Services-as-software: why "professional services don't scale" stopped being true around 2021
• Why "solve your own problem" isn't always right — and what to do instead
• The complicated-vs-complex problem framework for founder fit and capital structure
• First two hires were engineers, not lawyers
• Long-game hiring and contractor-to-full-time as a deliberate pattern
• The 30-question anonymous Google Form for surfacing blind spots
• "Twenty of them in the world" — the talent-infrastructure thesis behind Lighthouse
• Bear case and bull case for solo founding, the latter stated as lived experience

Guest: Minn Kim — founder and CEO of Lighthouse, the AI-powered immigration firm for frontier-tech companies and their hires.

David J. Phillips tried co-founders four times before he went solo. With $40,000 left in the bank after a stalled aquihire, he refounded the company alone — and built Fondo, the accounting platform now used by hundreds of YC and pre-seed startups. The conversation is part founder-confessional, part early-stage GTM playbook.

Topics covered:

• The four co-founder breakups across four prior startups
• Refounding with $40K and a single investor email
• The lived playbook for co-founder breakups (lawyer advice, severance + stock + move on)
• The four-question $40K filter for picking ideas you can ship solo
• The Sam Parr false bottom — first customer, three months of nothing
• The Delaware-franchise-tax mini-product wedge that produced the first ten paying customers
• Bear case and bull case for solo founding
• "Your co-founder lives in Claude now" — the closing argument

Guest: David J. Phillips — founder & CEO of Fondo, the accounting and tax platform for venture-backed startups.

The press was declaring the EV car market dead. Roughly $20B in EV investment had been cancelled. The Inflation Reduction Act had just expired. In that environment, Jimmy Douglas raised a $20M Series A from Lightspeed. Before Plug, Jimmy spent five years at Tesla running the largest US EV operation in the world. He left in 2024 to build Plug — the EV-first wholesale marketplace — then spent two years protecting a marketplace orthodoxy that was capping growth, until an investor in a fake board meeting asked the question that broke the company open. The chart bent that quarter. This is the most operator-dense episode we have recorded so far.

Topics covered:

• The contrarian timing: how Plug raised a $20M Series A from Lightspeed in the middle of an "EV hellhole"
• The China thesis behind the round — why US EV adoption will be unlocked by foreign OEM pressure, not by federal incentives
• 14 go-to-market pivots before the one that produced a hockey stick (Jimmy counted them by asking Claude to comb his board decks)
• Mike Maples Jr.'s "Reality Doesn't Negotiate" — and why disproving your hypothesis beats trying to prove it
• The fake-board-meeting question that broke Plug open: "You still have a balance sheet. What would you build right now if you started over today?"
• Killing the marketplace orthodoxy: opening an LLC subsidiary, taking the wholesale dealer license test, and the 16 → 429 unique-sellers-per-quarter hockey stick that resulted
• The two-things-need-to-be-true market test: venture-scale size and speed-to-power-law-outcome compatible with venture capital
• Tesla decision-making rigor: anticipate where the Wharton MBAs will find flaws before the meeting
• Self-manufactured constraints — Jimmy's coined term, paraphrased from five years of watching Elon at Tesla
• The factory-startup co-founder rule and why Jimmy went solo
• Hiring high-agency people away from big companies — sandbox, mission, and "if you have to convince them, they're not the right person"
• What market pull actually feels like — and the moment Jimmy realized Plug had it
• Investor pass etiquette: "you can tell a lot about a person by the way that they pass"
• Bear case for solo founding — credibility, network, skill-set required to recruit force-multipliers alone
• Bull case for solo founding — "the agency-maximizing play is to be solo founded and self-funded"
• AI is changing what venture wants — "vertical SaaS is going to zero," atoms-over-bits is back, balance-sheet risk is suddenly attractive again

Guest: Jimmy Douglas — Founder and CEO, Plug. Previously executive at Tesla running sales operations, delivery operations, internal fleet, internal communications, and used cars (the largest US EV operation in the world during his tenure). Plug: $6.7M seed from Floodgate, $20M Series A in 2026 led by Lightspeed with Galvanize, Autotech Ventures, Leap Forward, and Renn Global participating. $60M+ in used-EV sales facilitated since 2024 launch.
Host: Julian Weisser — Founder/CEO of Solo Founders and Co-Founder/CEO of On Deck/ODF.

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 it
• 90%+ of city council votes are pre-decided before the meeting starts
• Why "public comment is largely ineffective" and why the "local vocals" aren't representative
• Most city councils are rubber-stamp organizations
• Running for Orinda city council — and the $20K-minimum reality of nominally non-partisan local elections
• The civic-engagement on-ramp — join a commission as the lowest-friction way to start participating
• The newsletter-MVP-to-Hamlet arc — how a personal newsletter for residents became a civic AI company
• Easy-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 matters
• The Bold Italic acquisition, "This Is Your Life in Silicon Valley," and why you can't copy editorial voice
• Front-loaded advisor relationships as a substitute for the co-founder dynamic
• Pricing humility — "C-minus, D-plus" — and what to do about it
• Bear case for solo founding — resentment, no gut-check, easier to fracture
• The "let things simmer" leadership rule
• Bull 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. 

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 rate
• The co-founder of convenience trap
• 1 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 news
• Why Solo Founders doesn't run a Demo Day — the factory model critique
• True Solo / Free Solo / Juiced Solo — Julian's new three-type taxonomy with named examples
• Why 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 mode
• Bull 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 line
• Startups as art and the case against "contortionism"

Guest: Julian Weisser — Founder, Solo Founders. Host, Solo Founders Podcast. Formerly co-founder of On Deck.
Interviewer: David J. Phillips — Co-founder and CEO, Fondo. Solo founder.
