An honest comparison · updated 2026-07-13
Cofounder (cofounder.co) is a polished product with real capabilities — this page won't pretend otherwise. But the two products answer one question very differently, and it's the question that matters most the day your business starts working: whose business is it? Every claim below is quoted, sourced, and dated. If we got anything wrong, email hello@getsole.co and we'll correct it within a day.
"Cofounder cannot manage configuration after you graduate." — cofounder.co/pricing, on taking ownership of your own company's infrastructure (as of 2026-07-13)
That sentence is from their pricing page. Your company's code, database, and hosting live in their managed accounts, and taking ownership — "graduating" — is discouraged because the AI stops managing what you own. We built Sole on the opposite principle: you own everything from day one, and the AI keeps working for you anyway.
| Question | Sole | Cofounder (cofounder.co) |
|---|---|---|
| Who owns the infrastructure? | You, from day one. Sales go to your own Stripe account. Your site moves to your own free Vercel account in one click — and Sole keeps building it there. | Managed GitHub/Supabase/Vercel in their accounts until you "graduate ownership" — which their pricing page advises against.cofounder.co/pricing, 2026-07-13 |
| What happens if you cancel? | You keep everything — site, research, plan, brand, customer list. No revenue share, ever. | Not stated on their site as of 2026-07-13 — ask them before you build there. |
| What does it really cost? | First build free, no card. Then $50/mo flat with a hard compute cap. Anything that spends money waits for your written approval. | "Starting at $20/month usage included" — usage covers AI models, compute, database, ad spend and data purchasing; "you only pay more when your usage exceeds the included amount."cofounder.co/pricing, 2026-07-13 |
| Can you verify their results? | Yes — click them. Two live businesses (Burn Trail, Roaster's Round), an unedited build log with the mistakes kept in, and a public archive of every report. | "Over 10,650 companies are running on Cofounder" — we could not find a single named, linkable customer business on their site.cofounder.co, 2026-07-13 |
| Who is it for? | A person with an idea and no technical background. Plain language, no jargon — your co-founder reports like a human partner. | Technical founders — the product speaks MCP, custom APIs, and codebases. |
| The promise | Deliberately narrow: idea → a real business that can take money → its first sale. One promise, provable, every step logged. | "Run an entire company with AI" — engineering, sales, marketing, design, finance and ops.cofounder.co, 2026-07-13 |
| When the AI screws up | It's published. Our build log keeps the embarrassing entries — including the day our own demo forms were caught fake and fixed. | No public failure log as of 2026-07-13. |
An honest comparison cuts both ways. If you're a technical founder building a software product — an app with a real database, APIs, custom code — Cofounder's engineering agents go deeper than Sole does today. Their $20 entry price is a lower sticker than our $50 (though our first build is free and our bill can't surprise you). And they're building team features and SOC 2 for bigger companies.
Sole is for something different: real-world businesses — products, services, subscriptions — started by normal people, with the money flowing to them from day one.
Don't believe a comparison page — either of ours. Do this instead: type your idea into the live demo on our homepage and watch real agents research your actual market in 60 seconds. Then decide. That's the whole philosophy: proof, not promises.
One sentence in. A real business out — research, brand, plan, live website. Yours, entirely, from minute one.
