Fractional CTO Services

You need a CTO at the table. You do not need one full-time.

Senior technical leadership — board-level, vendor-facing, architecture-owning — at the cadence your business actually requires. Not a consultant who delivers reports. A technical executive who takes ownership.

The situation

Technical decisions are being made without a senior technical voice at the leadership table.

You are making architecture choices, vendor commitments, and technology investments without someone who can evaluate the long-term implications. Or you have engineering leadership that cannot operate at board level or speak credibly to investors and partners.

You are dealing with

Technology decisions made by committee — or defaulted to vendors whose interests differ from yours. Engineering leadership that is strong at execution but not positioned to represent technology at the board or investor level.

What you need

A technical executive who can represent engineering in leadership conversations, evaluate vendor proposals and architecture decisions, and give the board and investors a credible technical interlocutor.

What you cannot afford

Architecture decisions locked in by a vendor whose incentives are not aligned with your business. A technology investment made without a senior technical voice who understands both the business context and the engineering implications.

What a Fractional CTO delivers

Technical ownership at the leadership level — architecture governance, vendor evaluation, engineering strategy, investor technical dialogue — at a time commitment matched to your stage and budget.

Scope of engagement

Technical ownership across the areas where seniority matters most.

The engagement covers the full range of CTO responsibilities — weighted to what your business needs most at this stage. Board representation, architecture governance, and engineering team leadership are available from day one.

Step 1
Step 2
Step 3

Leadership

Board and investor

Technical representation in board conversations, investor due diligence, and strategic partner discussions. Architecture decisions explained in business terms. Technology risk communicated with evidence and recommendation.

As needed · Board-level cadence

Architecture

Technical governance

Architecture decision ownership — evaluating proposals, setting standards, reviewing vendor recommendations, and maintaining the technical roadmap. The senior technical voice that prevents decisions that look good in a slide deck and fail in production.

Weekly or biweekly

Engineering

Team and vendor

Engineering leadership coaching, vendor relationship management, hiring decisions, and delivery system oversight. The connection between technical execution and business strategy — so engineering is building what the business actually needs.

Regular embedded cadence

What you receive

An active technical executive, not a periodic report.

  1. 01 / 04

    Technology strategy

    A written technology strategy aligned to the business plan — architecture direction, build-vs-buy decisions, vendor strategy, and the technical investments needed to reach the next business milestone.

  2. 02 / 04

    Architecture governance

    Active oversight of architecture decisions — standards, patterns, review process, and the technical debt policy that prevents short-term decisions from becoming long-term constraints.

  3. 03 / 04

    Vendor and partner management

    Technical evaluation of vendor proposals, contract review from an architecture perspective, and ongoing vendor performance management — so vendors deliver what they promise and within the constraints the business requires.

  4. 04 / 04

    Engineering leadership development

    Structured coaching for engineering managers and technical leads — so internal leadership grows into the role and the engagement concludes with the business stronger than it started.

What happens when you are ready for a full-time CTO?

We help you hire one. The Fractional CTO engagement documents the technology strategy, architecture decisions, and leadership context that a full-time hire needs to take over effectively. We can advise on the CTO search, interview technical candidates, and support a structured handover.

Case studies

Case 1

Identified up to $220k/month in delivery-related revenue leakage

A software client had active development, ongoing releases, and a long-term product relationship, but delivery problems were starting to threaten the commercial value of the account.

Critical bugs, piecemeal releases, and work not tied to business objectives were creating a growing cost of poor quality. We built a business case around what poor delivery was costing and what fixing it could unlock.

Impact:

  • Estimated delivery-related revenue leakage: $50k-$220k/month
  • Broader potential monthly impact modeled around $315k

Case 2

Turned a small efficiency request into a $4.19M self-funding roadmap

A modest time-saving ask uncovered a far larger structural constraint sitting underneath the day-to-day work.

We mapped the real opportunity and built a phased roadmap that pays for itself as it is delivered, rather than a single large bet.

Impact:

  • Modeled value of the phased roadmap: $4.19M
  • Each phase funds the next

Case 3

Turned a routine review into a €1.05M resilience business case

A German funding intermediary with a well-built stack and a lean 24-person team had one systemic constraint: no tested recovery layer across eight interconnected systems — one WordPress database as the single source of truth for all of them.

A modest environment review uncovered €508K–€1.05M in modelled annual risk, unpriced and invisible until the numbers landed on paper. Reliability had quietly become the product.

Impact:

  • Modelled expected annual loss, quantified and phased out: €508K–€1.05M
  • Designed recovery time, from no tested restore: < 4 hrs

Common questions

What executives ask before engaging.

What does a fractional CTO do?+

A fractional CTO provides senior technology leadership to a company that needs CTO-level thinking without a full-time hire. Responsibilities typically include technology strategy, architecture oversight, engineering team leadership, board-level technical communication, vendor selection, and delivery accountability. Engagement scope is agreed at the start and adjusts as the company's needs change.

How much does a fractional CTO cost?+

Fractional CTO engagements typically range from €5,000 to €20,000 per month depending on scope, hours committed, and seniority. A 2-day-per-week engagement in Europe commonly costs €8,000–€15,000 monthly. The comparison point is a full-time CTO total compensation (salary + equity + benefits), which typically exceeds €200,000 annually for a senior hire.

When should a startup hire a fractional CTO?+

A fractional CTO is right when you have a working product but no technical leadership; when technical decisions are defaulting rather than being made deliberately; when a funding round requires credible technical oversight; or when you need to build and lead an engineering team but cannot yet justify a full-time hire.

What is the difference between a fractional CTO and a full-time CTO?+

A full-time CTO is an executive hire with full ownership of the technology function — typically 40+ hours per week, equity, and a multi-year commitment. A fractional CTO provides the same strategic and leadership capability on a defined days-per-week basis, without the hiring overhead, notice period, or equity dilution.

We already have a Head of Engineering. Is there a conflict?+

Usually not. A Head of Engineering typically owns execution — delivery, team management, day-to-day technical decisions. A Fractional CTO operates at the strategy level — technology direction, board representation, major vendor and architecture decisions. The two roles complement each other when the boundaries are clear. We define those boundaries at the start of the engagement.

What is the engagement model — retainer, hourly, or project-based?+

Monthly retainer for ongoing Fractional CTO work, with the scope defined in advance. Specific project work — a vendor evaluation, an architecture review, an investor briefing — can be scoped and priced separately. We do not bill hourly for Fractional CTO engagements; predictable cost matters to early-stage businesses.
