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.

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.

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.

Eugenia Kuyda has spent over a decade building at the frontier of AI consumer products. First by founding Replika in 2014, hitting 30M users in conversational AI before ChatGPT even existed. Now, building Wabi: giving everyone the ability to build personal software. In this episode, she breaks down why she’s repeatedly chosen the solo founder path, why “co-founders by pressure” create long-term damage, and what it actually takes to keep going when things get brutally hard.

This is a conversation about conviction, authorship, loneliness, team-building, and the emotional reality of leading through uncertainty. Eugenia shares the differ...

Charles Hudson is the founder and managing partner of Precursor Ventures, where he's invested in over 500 companies as a solo GP. He shares a data point that challenges the co-founder consensus: 25-30% of his portfolio companies lose a co-founder before Series A. In this conversation, he explains why talented solo founders beat mismatched teams, the real cost of dead equity, and why you should never give away 40% of your company just to make fundraising easier.

- The co-founder breakup rate: 25-30% before Series A

Paul Klein IV applied to 500 internships and got rejected from 498. Now he's the solo founder of Browserbase – a headless browser infrastructure company for AI agents – valued at $300M in under 14 months. He didn't choose to be a solo founder. He tried to find a co-founder and couldn't. In this conversation, he explains why that turned out to be the right thing.

Ben ran global teams at Travis Kalanick's Cloud Kitchens and left to build Polsia — an AI company builder — completely solo. Now he's hit $1.5M ARR in two weeks with 1,500 companies running on the platform.

In this conversation, we explore how his method of building might be the future of solo founding: his 80/20 framework for AI-native companies, why he designed his product after a video game about an AI apocalypse, the Daft Punk song on his about page, and what it actually looks like to run engineering, support, marketing, and strategy with zero employees.

This is a new show about building companies solo in the age of AI. Six months after launching the Solo Founders program, which has seen founders reach millions in ARR and sell to public companies and governments, this podcast brings together early-stage builders and experienced solo founders to share what's working, what's not, and what it actually looks like to grow a company without co-founders.
