Keep building with AI. We'll keep it safe.
Keep building with AI. A senior engineer makes sure what you ship is safe. For founders after launch, and for technical founders who want a senior second pair of eyes.
- Flat fee
- Never per user
- You own everything
Sound familiar?
You ship fast. Nobody's checking the work.
“You merge AI-written changes you can't fully review.”
“If the app breaks at 2 a.m., there's nobody to call.”
“Investors and enterprise customers want to speak to someone technical.”
“You can't justify a full-time CTO yet, but you need the judgement of one.”

Common questions
Questions about the Technical Co-founder Plan
Do I need a CTO if AI writes my code?+
AI writes code quickly. It doesn't take responsibility for it. You need someone who can judge what's safe to ship, handle incidents and answer investors. Many founders don't need that full-time yet.
Will you slow me down?+
The aim is to keep you shipping. Guardrails catch common problems before review, so your senior lead can spend their time on the changes that carry real risk.
How is it priced?+
It's a flat fee for an annual partnership, paid quarterly. It never goes up per user, so your costs don't rise just because your customer numbers do.
What happens when something breaks?+
Monitoring tells us early, and incident response is part of the plan. Your senior lead knows your product, so you aren't explaining it from scratch to a stranger when customers are affected.
Can you work alongside my developers?+
Yes. Your developers keep building, and your senior lead reviews each change before production and sets the guardrails for the AI tools your team uses.
Who will I work with?+
A named senior engineer who stays accountable for your product. You'll know who they are from the start, and they'll be the one on your due-diligence calls.
