How Project Brains matches expertiseWhen technology starts holding growth back.

Your team can deliver, but there is no senior technology leader connecting architecture, engineering priorities and investment decisions to the wider business strategy.
Establish clearer technology ownership, align priorities with the business and give teams senior direction.

The right CTO starts
with the right problem.
We don't start with a generic CTO job description. We start with what needs to change in the business, then define the technology leadership required.
Select a challenge below ↓What we're hearing
“We're growing, but our technology isn't scaling with us.”
Growth is exposing constraints across systems, technical decisions and the way technology is being led.
The question isn't
The better question is
What technology leadership will help the business scale?

Leadership need Strategic direction
Fractional CTO, full-time CTO or technology consultant?
The right model depends on the leadership gap, the stage of the business and how much ongoing technology ownership you need.
Fractional CTO
Senior technology leadership without immediately adding a permanent executive role.
Embedded strategic leadership with involvement shaped around the priorities of the business.
Fractional, interim or project-based.
Can provide ongoing direction across strategy, teams, architecture and transformation.
You need CTO-level decisions and leadership now, but the requirement does not justify a permanent executive hire.
Full-time CTO
A permanent executive responsible for technology leadership within the organisation.
Full-time executive involvement across the organisation.
Permanent employment.
Long-term executive ownership of the technology function.
Technology leadership is a permanent, full-time requirement and the organisation is ready to build the role internally.
Technology consultant
External expertise focused on a defined technology problem, programme or specialist area.
Typically focused on the agreed scope or specialist area.
Usually project or advisory based.
Usually advises or delivers within a defined remit rather than owning the wider technology function.
The problem is specific and does not require broader, ongoing CTO-level leadership.
What does “CTO as a service” mean?
CTO as a service is another way businesses may describe accessing external CTO-level leadership without hiring a permanent executive. The scope can vary, so the important question is what technology ownership and outcomes your business actually needs.
Start with the technology challenge rather than the job title. We can help you clarify the level and type of leadership required.
CTO-level leadership, shaped around what you actually need.
Fractional CTO engagements can vary considerably in scope. The right structure depends on the challenge, the level of leadership required and how involved your CTO needs to be.
Start with scope, not a generic day rate.
The cost of a Fractional CTO depends on the technology challenge and the level of involvement needed. A focused strategic review is a different engagement from ongoing leadership of a technology function.
We start by clarifying the outcome, responsibilities and expertise required, then shape the engagement around the work that needs to be done.
Advisory input, strategic ownership or hands-on leadership across the wider technology function.
The amount of CTO involvement required and how frequently leadership support is needed.
The scale of the organisation, technology environment, team and transformation challenge.
Sector knowledge, technical specialism and the leadership experience needed for the situation.
Different challenges need different levels of CTO support.
Project-based CTO support
Senior technology leadership around a defined challenge, decision or programme of work.
- Technology strategy
- Architecture reviews
- Technical due diligence
- AI & data strategy
Fractional CTO leadership
Ongoing CTO-level leadership for businesses that need strategic technology ownership without a permanent full-time CTO.
- Scaling technology teams
- Technology roadmaps
- Engineering leadership
- Technology governance
Interim CTO leadership
Senior technology leadership during a transition, leadership gap or period of significant business change.
- CTO transitions
- Leadership gaps
- Major transformation
- Preparing for a permanent hire
Access the level of leadership you need without designing the engagement around a full-time role.

From scaling pressure
to technology confidence.
A growing FinTech business needed its technology foundations to keep pace with growth — while preparing the business for Series B investor scrutiny.
Growth was exposing technology constraints.
The FinTech business was scaling, but its technology needed to be better aligned with the company's growth ambitions and upcoming investor scrutiny.
The requirement wasn't simply more technology capacity. It was senior technology direction around what needed to change next.
Align the technology roadmap with the next stage of growth.
Develop a clearer technology roadmap aligned with the company's growth targets.
Address technology constraints and reduce technical debt affecting scalability.
Prepare the technology position for scrutiny from Series B investors.

Technology became less of a barrier to growth.
Fractional CTO leadership can be most valuable when the business has reached a point where technology decisions materially affect growth, investment or risk.
Questions businesses ask
before bringing in a CTO.
Practical answers about fractional technology leadership, engagement models, cost and when a Fractional CTO may be the right fit.
A Fractional CTO provides senior technology leadership on a flexible basis. Depending on the challenge, this can include technology strategy, architecture, engineering leadership, technology roadmaps, team development, transformation and technology risk.
A Fractional CTO can be useful when technology decisions are becoming more important to growth, but the business does not necessarily need a permanent CTO. Common situations include rapid scaling, a technology leadership gap, architecture decisions, transformation, technical debt, investor scrutiny or preparing for a permanent hire.
The cost depends on the scope of responsibility, level of involvement, engagement duration, complexity and expertise required. Project Brains shapes engagements around the business need rather than assuming one fixed CTO package or level of commitment.
View Project Brains pricing →There is no single engagement length. Support may be structured around a focused project, a period of ongoing fractional leadership or an interim requirement. The appropriate duration depends on the challenge, desired outcome and level of leadership the business needs.
A Fractional CTO typically provides ongoing CTO-level leadership for part of the working week or month. An interim CTO is more commonly brought in temporarily to provide a higher level of day-to-day leadership during a transition, leadership gap or defined period of change.
A full-time CTO may make sense when the organisation needs continuous executive technology ownership as a permanent role. Fractional leadership can suit businesses that need senior CTO capability but want the level of involvement to remain flexible. The appropriate model depends on the business and technology challenge.
Yes. Fractional technology leaders can work alongside existing teams, providing senior direction, improving decision-making, coaching internal leaders and aligning technology priorities with wider business objectives.
“CTO as a service” is another term sometimes used for accessing CTO-level technology leadership without employing a permanent full-time CTO. The exact scope can vary, so the important question is what technology ownership, expertise and level of involvement the business actually requires.
