Start with a Health CheckNot ready for embedded leadership yet? Start with a $2,000 Technology Health Check (~2 weeks, written report) or Advisory (CTO on Tap) ($2,750 biweekly). Both are lighter entry points into the same senior CTO judgement.
Our virtual CTO services adapt to your stage, goals, and challenges. Here are the founders and executives who benefit most.
"I have deep domain expertise and a compelling problem to solve. But when engineers talk about microservices and infrastructure, I'm nodding without confidence. I need a tech leader who translates technology into business outcomes and stops me from making expensive mistakes."
"We grew from 10 to 80 people in two years. Our tech team is making decisions I can't evaluate. We're not big enough for a full-time CTO, but we're too big to wing it. I need a senior technical voice in the room with experience across multiple companies."
"Our CTO left. Or we're preparing for acquisition. Or we're migrating off a platform that's killing us. I need experienced leadership to navigate this transition. Not another consultant who'll hand me a slide deck and help me figure it out alone."
A CTO departure, an acquisition, or a migration that needs a full-time owner is a circumstance rather than a deeper commitment — and it rarely waits. Hiring a full-time CTO takes three to six months. An Interim engagement starts in one to two weeks: a senior fractional CTO from our network holds the seat, working under Reyem Tech and accountable to Reyem Tech for the outcome.
It will not always be Mario personally, and in a transition that is the point — the chair gets covered in a fortnight rather than a quarter, and the accountability stays in one place. From $15,000/month.
Not a fit
If any of these sound familiar, a fractional chief technology officer can bring senior technology leadership to the decisions that need an owner.
Your engineers are making architecture decisions you can't evaluate
Your investor is asking for a technical roadmap and you don't have one
You've had two senior developers leave in six months
You're about to sign your first enterprise customer who requires SOC 2
You've outgrown your technical co-founder's capacity
Your dev agency delivered something — and now nobody can maintain it
Pick the rung that matches where you are. Each step is a real, productized engagement.
How CTO as a service compares to the alternatives.
| Metric | Fractional CTO | Full-Time CTO | No CTO |
|---|---|---|---|
| Annual cost | $96,000 - $192,000 | $300K - $500K+ | $0 upfront |
| Time to start | 1-2 weeks | 3-6 months to hire | N/A |
| Strategic depth | Senior, cross-industry | Deep but single-company | None |
| Hidden cost | None | Equity, benefits, recruiting fees | Bad architecture, failed hires, lost investors |
A Fractional CTO — a fractional chief technology officer — is an experienced technology executive who provides strategic leadership on a part-time or contract basis. Unlike a full-time CTO, an interim technology executive delivers the same calibre of guidance at a fraction of the cost, making enterprise-grade technology leadership accessible to startups and SMBs.
Reyem Tech publishes its prices rather than hiding them behind a quote. Most engagements start with a fixed-scope Technology Health Check at $2,000 (~2 weeks). From there, ongoing advisory (CTO on Tap) starts from $2,750/month and an embedded Fractional CTO retainer starts from $8,000/month. These are Reyem Tech’s configured monthly fees; the right tier depends on the leadership coverage your team needs.
Startups should consider a Fractional CTO when they need strategic technology leadership but cannot justify or afford a full-time executive. Common triggers include preparing for fundraising, scaling the engineering team, evaluating build-vs-buy decisions, or needing architecture guidance for a major product initiative. The trigger to hire a fractional CTO is usually a decision that would be expensive to reverse, not a gap in the org chart.
CTO as a service is the chief technology officer function delivered as an ongoing service rather than a full-time hire. You agree on the leadership scope and cadence, then pay the published monthly fee for work such as architecture decisions, engineering leadership, vendor choices, and board-level reporting. Reyem Tech provides that leadership directly and stays accountable for the work in scope. Most engagements start with the fixed-scope Technology Health Check at $2,000, which carries no retainer.
Start by writing down the decisions you need owned over the next two quarters — architecture, the first engineering hires, vendor selection, or a funding milestone — rather than a list of technologies. Then look for evidence that the person has owned similar decisions and will stay accountable for the agreed work. You do not have to commit to a retainer to assess fit: the fixed-scope Technology Health Check at $2,000 produces a written verdict in ~2 weeks.
CTO on Tap is the advisory retainer: $2,750/month for 2 sessions (biweekly) / $4,000/month for 4 sessions (weekly), with the published cadence measured in sessions. Fractional CTO is the embedded leadership retainer: tiers of 5, 10, and 15 hours per week at $8,000 / $12,000 / $16,000. The offers have different scopes and commitments; choose by the leadership coverage and responsibilities your team needs.
A consultant typically delivers a report or recommendation and moves on. A Fractional CTO engages on a defined cadence during the engagement window — owning the architecture decisions in scope, mentoring your developers, and staying accountable for the execution they commit to. Depth of engagement without the round-the-clock operator commitment of a full-time hire.
Yes. The engagement can combine strategic technology leadership with hands-on implementation. We can work alongside your team on agreed technical priorities, while keeping scope, ownership, and delivery expectations clear before the work begins.
Start with a free 30-minute discovery call. If the Technology Health Check is the right next step, it takes about two weeks; ongoing leadership can begin from month one. We confirm availability and scope before an engagement starts.
We agree on confidentiality, data access, and intellectual-property terms as part of defining an engagement. Before sharing sensitive information, review the contract terms and confirm that the access and handling arrangements fit your organization’s requirements.
Some clients do transition to full-time arrangements. We also help build the internal CTO role specification and support the hiring process for an eventual full-time technology executive.
A Fractional CTO can complement internal engineering leadership with outside perspective, board-level communication, and cross-company experience. The role and decision ownership should be agreed with your VP of Engineering before the engagement begins.
Yes. A part-time CTO can translate technical trade-offs into business decisions, help you evaluate engineering plans, and give you a senior technology counterpart without expecting you to become an engineer. We agree which decisions and responsibilities the engagement will cover.
It may be a fit when important technology decisions need experienced ownership, but a full-time CTO role is not yet the right level of commitment. Consider the decisions ahead, the experience your current team has, and how much ongoing leadership you need. A discovery call can help establish whether the Health Check, advisory, or embedded tier fits.
Prioritize decisions by their business impact and the cost of changing them later. Often that means clarifying the customer problem, choosing an architecture your team can operate, hiring for the skills the roadmap requires, and checking vendor dependencies. The right priorities depend on your product, stage, constraints, and team.
