Fractional CTO
Fractional Chief Technology Officer
Technical direction for the product you build and sell.
What a CTO does
A CTO owns the technology behind your product. They set the architecture, lead the engineering team, and make the build, buy, and hire calls. A fractional CTO gives you that senior judgment a few days a month. You get a clear technical plan without a full executive salary.
Signs you need a CTO
- You are founder-led and nobody senior owns the tech stack.
- Releases are slow, risky, or keep breaking things.
- You are about to raise money and need a credible technical story.
- You rely on an agency or freelancers and cannot tell if the work is good.
- You need to hire engineers and are not sure who or how.
What we own
- Set the technical vision and a roadmap the business can read.
- Review architecture, code quality, security, and hosting costs.
- Hire, mentor, and organize the engineering team.
- Choose vendors and tools, and manage outside development partners.
- Represent technology to the board, investors, and customers.
Your first 90 days
-
Days 1 to 30
Listen and assess. We review the code, the team, the vendors, and the backlog, then share what we found in plain English.
-
Days 31 to 60
Set direction. We agree on architecture choices, priorities, and the few changes that unlock the most progress.
-
Days 61 to 90
Build the rhythm. Delivery cadence, metrics, and hiring move forward so the plan keeps working after each session.
What you walk away with
- A technical roadmap tied to business goals.
- An honest assessment of your platform, risks, and tech debt.
- A delivery process your team trusts and can repeat.
- A hiring plan, and help running it.
