Not yet at critical mass
The volume of decisions does not justify a full-time in-house CTO, yet technical debt accumulates for lack of arbitration. The fractional format lays the foundations before they become expensive.
Service
Fractional CTO
Senior technical leadership a few days a month, with the same accountability for results as an in-house role: trade-offs, governance, roadmap and team mentoring.
Definition
What is a fractional CTO?
A fractional CTO — also called a part-time, shared or temporary CTO — is a technical leader who performs the role for your organization a defined number of days per month, instead of in a full-time position. They carry the technical strategy, settle the structuring choices, mentor the existing teams and represent the technical function to executive management, the board or investors.
This is not a one-off consulting assignment. It is a leadership function, exercised over time, with the same accountability for results as an in-house role — without the cost, the hiring lead time or the full-time commitment.
When the format fits
Three typical situations
The choice does not depend on company size alone, but on the nature of the need: continuous day-to-day steering, or regular strategic trade-offs.
An organization in transition
Between two CTOs, or in the middle of restructuring the IT department: the function has to be held while hiring proceeds, and the governance put in place has to be transferable.
Recurring senior arbitration
An executive team that has to settle an investment, an acquisition or a platform change, without bringing that skill in-house permanently.
And when it does not
When a full-time CTO is the right answer
When technology is directly the core of the business and emergencies are lived in real time, continuous presence changes the nature of the role: an in-house CTO builds a daily relationship with the teams and embodies the function in the company culture. A few days a month cannot do that. Saying so is more useful than selling a format that does not fit.
Scope
What the function covers
Six areas, adjusted at scoping depending on what is already covered in-house.
01
Strategy and roadmap
The 3, 6 and 12-month technical trajectory, aligned with business objectives and arbitrated with executive management.
- Dated technical roadmap
- Prioritization of workstreams
- Alignment with the business plan
02
Trade-offs and architecture decisions
Structuring choices are settled, written down and dated — not left pending between two meetings.
- Architecture Decision Records (ADR)
- Architecture reviews
- Technical debt versus new features
03
Governance and committees
A simple framework stating who decides what, when, and on the basis of which information.
- Architecture committee
- Technical leadership review
- Tracking indicators
04
Vendors, budget and risk
Steering suppliers and software vendors, controlling the technical budget and tracking dependency risk.
- Contract and commitment review
- Budget tracking and FinOps
- Reversibility and vendor lock-in
05
Team leadership
Raising the skill level and setting the working standards of the existing teams, without replacing them.
- Mentoring technical profiles
- Code and design reviews
- Engineering standards and practices
06
Representing the technical function
Carrying the technical narrative to the executive committee, the board, investors or an acquirer.
- Executive committee and board
- Technical due diligence
- Technical files for a funding round
Process
How the engagement runs
The four TEAF phases applied to technical leadership: understand, decide, steer, hand over.
Step 1Weeks 1–2
Current state and pending decisions
- Inventory of technical decisions left pending
- Reading the existing setup: architecture, debt, vendor contracts
- Identifying the sponsor and the committees to run
Step 2First month
Roadmap and rules of the game
- Technical roadmap at 3, 6 and 12 months
- First architecture decisions written down and dated
- Governance framework: who decides what, and when
Step 3Steady state
Steering
- Architecture committee and technical leadership review
- Trade-offs, architecture reviews and team mentoring
- Steering vendors, budget and risk
Step 4End of engagement
Handover
- A complete and up-to-date decision record
- Governance that can be picked up without starting over
- Scoping of the profile to hire, if bringing the role in-house is the next step
What stays with you
A transferable function, not a dependency
Every structuring decision is written down, dated and motivated. At the end of the engagement, the roadmap, the decision record and the governance framework stay with you and can be used by an in-house CTO, a successor or a team without outside support.
A fractional CTO engagement can also be structured from the outset to prepare a hire: scoping the role, defining the profile to look for, and putting in place the governance the future in-house CTO will pick up without starting over.
Engagement framework
What this is not
This is neither staff augmentation, nor a permanent on-site presence, nor the supply of personnel. The engagement runs remotely, over an agreed number of days, with identified deliverables — and it does not consist of producing code in place of your teams.
FAQ
Fractional CTO: the recurring questions
Fractional CTO or full-time CTO: how to choose?
Three questions usually settle it. Is the volume of technical trade-offs daily, or rather weekly and monthly? Is the dominant subject continuous execution, or defining a strategy and supervising it? Does the budget allow you to attract a senior profile full time? When technology is the core of the business and requires continuous presence, an in-house CTO is the right answer: the fractional format is not.
What is the difference with an interim or temporary CTO?
An interim CTO holds the position full time for a limited period, usually to cover a departure. A fractional CTO performs the same leadership function, but on a reduced number of days and over the long run. The two meet in one case: an organization between two CTOs, where the fractional format holds the function during the hiring process and prepares the arrival of the permanent holder.
How many days per month?
The rhythm is set during scoping, according to the volume of decisions to carry and the committees to run. In practice it often sits between one and four days per month, split between committees, trade-offs and substantive work on the roadmap. It can be raised temporarily during a critical phase, then return to the nominal rhythm.
Does a fractional CTO write code?
No. This is a leadership function: arbitrating, deciding, mentoring, documenting. Producing code instead of the teams would spend on execution the days that must serve governance, and would create the very dependency the engagement exists to avoid. Code reviews, architecture reviews and mentoring, on the other hand, are part of the role.
In which countries can the engagement take place?
Engagements are run remotely from Quebec, in French and in English, for Canada, France, Belgium, Switzerland and Luxembourg. Occasional travel remains possible for the meetings that warrant it.
How is a fractional CTO engagement priced?
The engagement is scoped before it is priced: number of days per month, committees to run, expected deliverables and duration. The quote is drawn up after a free initial conversation. There is no single rate card — the volume of decisions to carry varies greatly from one organization to the next.
How does an engagement start?
With a free initial conversation, then scoping: current state, pending decisions, committees to put in place. The scoping questionnaire on this site produces a structured brief, so that the conversation starts on substance rather than on discovery questions.
