Fractional CTO and interim CTO.

A Whitesmith fractional CTO gives your company senior technical leadership without a full-time hire, and brings AI into how your team delivers.

Our CTOs set technical direction, steady delivery and grow the team, part time or for a defined period. Every engagement starts with listening: to your people, your codebase and your roadmap.

"Working with Rafael as our fCTO over the past six months has been incredibly impactful for our young tech company. He has helped us identify gaps in leadership & strategy, staff resource, and tech skills. Once those gaps were identified, he worked with us to develop plans to tackle each one and checked in weekly to ensure we had everything we needed for success. After our initial six month project with him, our product team is working faster, harder and more efficiently with great results for our users. I would highly recommend working with Rafael as your fCTO to take your product team to the next level!"

Fractional or interim CTO?

The right one depends on whether you need technical leadership for a defined period of change or on an ongoing basis. Either way, your CTO works inside your team.

Interim CTO

For a defined period of change: a CTO leaving, a funding round, a product milestone, or a restructure where engineering needs stability. Typically 3 to 6 months, part or full time, with the scope and handover plan agreed at the start.

Fractional CTO

For companies that need sustained technical leadership but not a full-time hire. Your CTO works alongside the team on an ongoing basis, setting technical direction, improving how work gets delivered and building the engineering culture you need to scale.

Who you'd work with

Your CTO will be Rafael or João.

Designs how organisations run AI programmes, from ownership and weekly rhythm to what gets measured. He is also fractional CTO for a client in the advertising industry, guiding their technology approach and AI adoption.

Implements AI operating models inside live engineering organisations in the retail and financial industries. He owns the AI development playbook these teams follow and coaches them as they adopt it.

How a Whitesmith CTO works

Whitesmith has embedded technical leaders inside organisations since 2012. Your CTO spends the first days listening: interviewing people at every level and getting to know the codebase and the team before proposing any changes. That way the plan fits how your team actually works.

Our CTOs also bring AI into delivery as part of the job. Within a year at Electica, the team moved from limited AI adoption to AI-enabled workflows across development and product management, and the time to write a product spec fell from a full day to an hour.

Fractional CTO questions

When technical decisions are outpacing the leadership available to make them. That usually happens during rapid growth, a major product build, a funding round, or after a CTO leaves.

A fractional CTO sets technical direction, makes or guides the big technology decisions, improves how the team delivers, and connects engineering work to business goals. A Whitesmith fractional CTO also brings AI into the team's delivery workflow.

By listening first. In the first days, your CTO interviews people at every level and reviews the codebase and team set-up before suggesting changes, so the recommendations fit how your team already works.

It depends on how much senior technical leadership you need each week. If you need a CTO's judgement but not five days a week of it, a fractional CTO fits. If you need someone in the role every day for the long term, hire full time, and consider an interim CTO to hold the role while you recruit.

No. Early-stage companies with simple technical needs, and companies that already have strong technical leadership, are often better off investing elsewhere. Some only need a CTO for a period of change, which is what an interim engagement is for.

Interim engagements typically run for 3 to 6 months. Fractional engagements run from a few months to over a year, and you can extend or shorten them as your needs change.
