Ben Cera was our very first guest, back when Polsia had just crossed $1.5M in annualized revenue. About seven months later, Polsia had passed a $20M run rate. Now he's back, live on stage with Julian at the Outliers Summit in New York, still the only founder of a company that raised $30M at a $250M valuation. Ben explains why he regrets bringing on co-founders just to raise money, why the technical co-founder is now AI, and why you should try solo before you go looking for one.
Topics covered:
- Building a startup as art
- What a one-person company looks like at this scale
- Raising on a deck with two co-founders who debated instead of decided
- Why not deciding is worse than a wrong decision
- Why Polsia is "AI Slop" spelled backwards
- Agents as digital humans with a personality
- True solo, free solo and juiced solo
- Who Polsia's customers really are, and why every setup step loses people
- Founders as creative directors
- "Aren't you lonely?" and the case for solo founding
Guest: Ben Cera, founder of Polsia, the AI that builds and runs companies.

A round can start before a big lead check arrives. Julian argues it starts with small checks from great people, and that for a solo founder those checks are about momentum as much as money. In conversation with Ari, he covers what angels actually do, how to make them want to introduce you, and his view of the risks facing co-founded and solo-founded companies.
Topics covered:
- Why $1K to $5K checks from great people start rounds
- Never take angel money for a promised intro; make yourself easy to forward
- Angels as a fan base: why more is better than fewer
- What angels want vs. what lead VCs want
- Venture scale as a choice and a commitment
- Co-founder breakups vs. solo founders giving up; momentum vs. burnout
- Why your customers (and your competitor's) make great angels
AI agents now write the code, review it and write the tests. Chai Choudhary, solo founder of Workers IO, is building the proof layer that shows whether any of it works. A conversation about why "nobody's buying code" anymore, the first company he sold too early, killing ideas fast, and why founders should start solo.
Topics covered:
- AI-written code and the growing gap between engineers and their own codebases
- Why proof that software works is becoming the product
- Starting late: code on paper, one lab hour a week, no internet until college
- Timing, and the cost of selling too early
- Runway as a decision tool
- Killing two ideas fast, and never marrying a solution
- Content-led distribution for a deeply technical product
- Solo vs. co-founders: equity for exceptional hires, and the honest bear case
Guest: Chai Choudhary, founder and CEO of Workers (https://workers.io).

Six solo founders on the question underneath every startup: how do you choose a company you'll still want to be running in ten years? Julian revisits conversations with Dhravya Shah (Supermemory), Francis Davidson (Odessia), Thais Castello Branco (Taste Labs), Flo Crivello (Lindy), Claire Vo (ChatPRD), and Paul Bakaus (Impeccable), and pulls one idea from each that deserved more spotlight.

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.
Ali Ansari never had a co-founder - he didn't know they existed. In this episode, the micro1 founder tells Julian how he went from selling his dad's shoes on eBay at 12 to deleting his profitable AI recruiting business and going all-in on training data for frontier AI labs.
Topics covered:
- The three signals it's time to move on from a business
- Deleting $7M in run rate, and why only founders can inject risk
- Solo by default: building a founding team instead of hunting for a co-founder
- micro1's async culture: open threads, final actions, no meetings
- The Spirit Airlines data bid and the AI data gold rush
- Why micro1 refuses to sell training data to America's adversaries
Guest: Ali Ansari — founder and CEO of micro1, the AI training-data company behind frontier-lab training environments.
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. A conversation about why agents are locked out of the tools teams live in, and what founding looks like the second time — alone, on purpose.
Topics covered:
- Why Slack's architecture can't serve AI agents (the locked office building)
- Agents as coworkers: identity, permissions, etiquette, and the first 90 days
- Market-personality fit: picking a problem worth ten years of your life
- The solo founder's hiring playbook: attract don't chase, contract-to-hire, minimalist headcount
- Co-founder the first time, solo the second: the bear and bull case
Guest: Sara Du — founder & CEO of Ando; previously co-founder & CEO of Alloy Automation; Thiel Fellow.
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.

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.
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:
Founders: Utkarsh Dalal (GameNative), Ryan Junejo (Crash Labs), Charlie Kahn (Brio), Andy (Phenomni). Host: Julian Weisser.
