Fractional CTO · Part time, senior, hands-on
Fractional CTO for founders building with AI
A fractional CTO is a senior tech leader who works with you part time. You get the calls a full-time CTO would make: what to build, which tools to use, who to hire and what it should cost. Ours comes with a build team behind them, so plans turn into software.
When a fractional CTO makes sense
You're a founder who isn't technical
You know the market. You need someone on your side of the table for the tech calls.
You built it with AI tools and it's growing
Lovable, Bolt or Cursor got you to launch. Now real users are in and it needs a grown-up.
Your developers need a lead
You have a team or a contractor, but nobody senior is checking the work or the plan.
Investors are asking tech questions
You need clear answers on your product, your AI and your costs. In plain words.
What your fractional CTO does
Sets the product and tech plan
What to build first, what can wait and what it should cost.
Picks the tools and the AI
The right stack and AI models for the job, chosen so you're not locked in.
Checks the work
Reviews code, security and AI answers, so problems get caught before your users find them.
Leads the builders
Your developers, ours or both. One senior person keeps them on the plan.
Watches the costs
Hosting, AI usage and build spend. You see the numbers every month.
Talks tech for you
With investors, partners and new hires. You get a clear voice in the room.
Fractional CTO or full-time CTO?
Cost
A full-time CTO is a senior salary, and often equity too. A fractional CTO is a monthly fee for the hours you need.
Speed
Hiring a CTO can take months. A fractional CTO can start with you after one call.
When to switch
Once the product earns enough to need someone full time, we help you hire them and hand over.

What is a fractional CTO?
A fractional CTO is a senior tech leader who works for your business part time. They make the big tech calls, lead the builders and keep the product on plan, without the cost of a full-time hire.
How much does a fractional CTO cost?
It's a monthly fee based on the hours you need. We quote it after a free product call, once we know your product and your team. Any build work is quoted on its own, at a fixed price.
When should I hire a fractional CTO?
When tech choices are slowing you down or scaring you, and a full-time CTO is too much right now. Common times: before a first build, after a quick AI-built launch, or before raising money.
Can a fractional CTO help with AI?
Yes. That's most of our work. Your CTO picks the AI models, tests the answers, watches the running cost and makes sure you can switch models later without a rebuild.
Will my fractional CTO write code?
They lead, plan and review. When you need code written, our build team does it, or your own developers do with our CTO checking the work.
Do you give advice only, with no build?
Our CTO work is tied to a software product. If you only want general advice on AI across your business, our sister brand handles that. Tell us on the call and we'll introduce you.
