What is a fractional CTO, and when does a growing business need one?

NinjaDev — Built here. For everywhere.

What does a fractional CTO actually do?

They own the technology decisions a growing company keeps postponing: what to build, what to buy, which vendors to trust, how to sequence the roadmap, and how to keep projects on time and on budget. They don't replace your developers; they make sure the right things get built.

How is that different from hiring an agency?

An agency is usually hired to deliver a defined project. A fractional CTO works on your side of the table — scoping work, reviewing proposals and holding vendors accountable — so you're not relying on the people selling the work to also tell you what you need.

What does a fractional CTO cost?

Market guides put advisory engagements (about 10–15 hours a month) at roughly $4,000–$10,000 per month, with more hands-on engagements higher (A.Team). NinjaDev's Fractional CTO / Product Lead engagement starts at $6,000 a month.

When does a business need one?

Common signs: you're about to spend significantly on software and aren't sure you're buying the right thing; projects keep slipping; you rely on one developer or vendor nobody can check; or you want to use AI but don't know where it fits.

When is it too early?

If your technology needs are a website and a few off-the-shelf tools, you likely need a good build partner, not a fractional executive. Start with an audit instead.

Can a fractional CTO also build?
Some do; at NinjaDev the same senior team can lead and deliver, so strategy and execution stay connected.
