How much does a fractional CTO cost? Published 2026 prices, compared

You need senior technical judgement. An investor asked about your architecture, or you're about to hire your first engineers.

A full-time CTO is a big step. The median wage in the federal job category that includes CTOs was $175,140 in May 2025 (US Bureau of Labor Statistics, Sep 2026).

Fractional prices look chaotic too. One provider starts at $60 an hour (HyperNest Labs, Sep 2026).

Another's top tier is $25,000 a month (Kompella, Sep 2026).

The twist: they aren't rival prices for the same thing. They buy different amounts of time.

This guide sets out six providers' published prices, what the role covers and when it pays. Ours are included.

1. What a fractional CTO is

A fractional CTO is a senior technology leader who works for your company part time, usually a set number of hours or days a week, on a monthly retainer or hourly terms.

They own the decisions a full-time CTO would own: architecture, vendors, hiring, security, and what to tell investors.

The role goes by other names too: part-time CTO, virtual CTO, CTO as a service. Check what each provider means by it.

Two other roles get mixed up with it:

• A technical consultant answers a defined question, then leaves. A fractional CTO stays and is accountable for the outcome.
• An interim CTO fills an empty seat full time for a set period, until a permanent hire starts.

2. Why cost is the first question

Searches for "fractional cto" were 3.6 times their level a year earlier when we checked Google Trends in September 2026 (Google Trends, Sep 2026).

In the same research, the top question Google suggested alongside the search was what a fractional CTO costs.

The confusion has a cause. "Fractional CTO" covers advisers who meet once a month and engineers who ship code every week.

Many answers online quote market ranges. We went to providers' own pricing pages instead, and used only what they publish.

We don't average them or estimate. Each figure links to the page it came from.

3. What a fractional CTO costs: published prices

These are prices providers publish on their own pages. We checked each one in September 2026.

• HyperNest Labs: from $60 an hour, with no retainers. It says most clients use 40–80 hours a month, about $2,400–4,800 (HyperNest Labs, Sep 2026).
• Justin McKelvey (independent): $5,000–15,000 a month for embedded work, about 8 hours a week, for 3–12 months (Justin McKelvey, Sep 2026).
• Kompella: Advisory at $8,000 a month for one day a week, Fractional at $15,000 for two days, and Embedded at $25,000 for three or more (Kompella, Sep 2026).
• Continuum: a Partner retainer from $500 to $10,000 a month, in five levels. The top level, at $10,000 a month, is its full fractional CTO seat (Continuum, Sep 2026).
• Tristella Advisors: $10,000–20,000 a month for 20–60 hours of embedded work (Tristella Advisors, Sep 2026).
• 27 Colab: from $5,000 a month, for about a day a week.

What the prices tell you:

• Time is the main variable. Kompella says its cost scales with the days a week you need (Kompella, Sep 2026).
• Building and advising are priced differently. Hourly billing suits hands-on work; a retainer buys a standing seat at the table.
• Short commitments are available. HyperNest Labs has no retainers, and Kompella runs month to month.

To compare two quotes fairly:

• Convert both to hours a month. A day a week and a monthly hour bank are different units.
• List what's included. Code review, hiring, board meetings and on-call cover may be priced separately.
• Check the notice period. It's the real length of your commitment.
• Ask about capacity. Find out how many other clients share those days.

4. What a fractional CTO does

The job changes with your stage. Most of it falls into seven areas:

• Technical direction. A roadmap that fits the business plan and the runway.
• Expensive decisions. Architecture, build versus buy, which vendor, which cloud.
• Vendor oversight. Reviewing an agency's code and estimates, so you aren't taking them on trust.
• Hiring. Writing the role, running the technical interview, onboarding the first engineers.
• Basics in place. Source control you own, tests in CI, access control, backups and error reporting.
• Investor and buyer questions. Architecture answers, security questionnaires, technical due diligence.
• Building, sometimes. Some fractional CTOs also write code. Ask which kind you're hiring.

A good one also says no. Fewer features, a cheaper vendor, or no rebuild at all can be the right call.

By the end of the first month, you should have:

• A written read of the current system, the team and the vendors.
• Access to every account, held in the company's name.
• A short list of decisions, each with an owner and a date.
• A plan for the next quarter that the CEO can explain without help.

5. When to hire one (and when not to)

Bring one in when:

• You're about to choose a stack, an agency or a platform you'll live with for years.
• A non-technical founder is managing developers and can't judge the work.
• A raise or a sale is coming, and someone will ask technical questions.
• Your CTO or only senior engineer has left.
• Releases keep slipping and nobody can say why.

Timing matters more than the rate. Advice is cheapest before a big decision, not after it has gone wrong.

Don't, when:

• You need a full-time builder. Hire an engineer or a studio.
• You have a technical co-founder with the time and the experience.
• You need one answer, once. Pay for a review instead.

6. Fractional vs full-time vs agency

Each option buys something different. Here's how they compare.

You can combine them. A fractional CTO sets direction and checks the work; an agency or a small team builds.

That pairing covers the agency's main risk: someone on your side reads the code.

Each option also has a cost that doesn't show on the invoice:

• Full-time: the months spent recruiting, and the cost of a wrong hire.
• Agency: change requests, and knowledge that leaves when the project ends.
• Fractional: context lost between days, unless decisions are written down.

7. When to move to a full-time CTO

Fractional is a stage, not a permanent state. These are signs you've outgrown it:

• Decisions wait for the fractional days.
• The engineering team is big enough that managing people fills the week.
• Technical leadership is needed every day, not one day a week.
• You're hiring engineering managers, and they need someone full time to report to.

A good fractional CTO plans for this. They help write the role, interview the candidates and hand over.

8. Questions to ask before you sign

Put these to any fractional CTO, including us:

• Will you write code, or direct others? Both are valid. Know which one you're buying.
• How many hours or days, and how fast do you reply? Get both in writing.
• Can we stop with notice? Kompella, for one, publishes month-to-month terms with 30 days' notice (Kompella, Sep 2026).
• Who owns the repositories, cloud accounts and domains? Your company should, always.
• Do you take referral fees from vendors you recommend?
• Who else do you work with? Check for conflicts, such as a direct competitor.
• What does a normal week look like? Meetings, code review, written updates, and when each happens.
• What do you hand over when you leave? Documentation, access, and decisions written down.
• Can we start with a paid first read? Some providers sell one. CTO on Demand offers a 90-minute "Reality Check" for $750, credited toward any engagement (CTO on Demand, Sep 2026).

9. What we charge

Our fractional CTO engagement starts from $5,000 a month, for about a day a week. Jesus is the fractional CTO.

If marketing leadership is the other gap, Elizabeth works the same way as a fractional CMO, also from $5,000 a month.

Two fixed-fee ways to start:

• Before an MVP: a two-week launch scoping sprint at $3,500. You get a prototype, a fixed build quote, a go-to-market plan and the deck story.
• Before a raise or a sale: an exit-readiness review at $12,000. You get a written report on code, tests, security basics, WCAG, analytics and consent, licences and the data-room story.

Every fixed fee is credited to the next phase if you continue. Ad-hoc work is $80–150 an hour.

We contract through 27 Colab LLC, not payroll, and report in writing every week.

We work remotely or on site across Miami–Fort Lauderdale, in English or Spanish.

10. Do this first

List the three technical decisions you'll make in the next 90 days.

If you can't name three, you don't need a fractional CTO yet. A one-off review will do.

If you can, and none of them has an owner, that's the job.

Write the list down before any call. Ask each candidate how they'd approach the first decision on it.

Then bring it to a call, with us or with anyone else.
