Fractional CTO or Fractional Technical Operating Partner: What a PE Firm Should Hire
A PE firm should hire a fractional CTO when one portfolio company needs a senior technology executive for a set period, and a fractional technical operating partner when the work spans several companies or runs across the deal cycle from diligence to exit. A fractional CTO is one person reporting into one management team, which suits a company whose main gap is technology leadership and which already has engineers to lead. A fractional technical operating partner is usually a senior lead with a team behind it, which suits a deal team that needs diligence, integration, RevOps and data work carried out by the same people, on the timeline in the value creation plan.
Step 1: List the technical work in the value creation plan before choosing a title
Most hiring decisions in this area start with a job title, and the title then sets the scope of the engagement. The common mistake is to hire a fractional CTO for a company whose value creation plan is mostly CRM consolidation, board reporting and pricing changes, which is revenue operations and data work more than technology leadership.
To check, go through the plan line by line and mark each initiative as leadership (architecture decisions, vendor strategy, hiring a permanent CTO), execution (migrations, integrations, data pipelines, forecasting) or both. If most lines are execution, a single fractional executive will spend the engagement either building alone or managing contractors, and the deal team should price that in before signing anything.
Step 2: Decide whether the work sits in one company or across the portfolio
A fractional CTO works inside one company's management team, and that arrangement fits well when the company has its own engineering staff and needs someone to set direction for them. Where the same work repeats across holdings (the same CRM rollout, the same reporting standard for the board, the same AI pilot in several companies), a separate fractional CTO in each company tends to produce several different answers to one problem.
The deal team can check this by listing which portfolio companies share a system, a reporting requirement or a planned initiative over the hold period. If the list has more than one or two names on it, a provider that works across the portfolio with one team will usually cost less in total and give the fund comparable reporting from each company.
Step 3: Check who covers technology diligence and the first 100 days
A fractional CTO is often engaged after close, so the technology diligence findings were written by one party, the Day 1 integration plan by another, and the new executive inherits both without having worked on either. That gap shows up as findings with no cost estimate attached and integration steps that nobody has sized.
Ask whether the people who run diligence will also run the first 100 days, and read a sample diligence report to see whether each finding comes with an estimate of the work, the cost and who would do it. A report that ends at a list of risks is useful for the investment committee, while one that sizes the remediation is useful for the operating plan as well.
Step 4: Confirm who does the build work
Many fractional engagements produce a sound roadmap and then slow down because the portfolio company has no one free to carry it out, and the operating partner ends up hiring a vendor partway through the hold. The second vendor then spends its first weeks relearning what the first adviser already knew.
Ask the candidate to name the people who will configure the CRM, write the data pipelines and move the reporting, and to describe the change control on that work (versioning, testing and an audit trail). If the answer is a list of subcontractors still to be found, the deal team should expect a second contract for execution and plan the budget around it.
Step 5: Settle ownership, handoff and exit readiness at the start
Systems built during the hold have to pass a buyer's diligence at exit, and a frequent problem is that code, accounts or data sit in a vendor's name or depend on the knowledge of one person. Fixing that during a sale process takes time the sellers rarely have.
Write into the contract that the portfolio company owns its code, accounts and data, and ask for a handoff plan with training for the internal team. A practical test is whether the company's own staff could run the reporting and the CRM without the provider for a full quarter before the sale process begins.
A worked example: DevriX as a fractional CTO and private equity operating partner
DevriX is a technical value creation and revenue operations firm for private equity firms and their portfolio companies: it executes the technical and revenue workstreams of the value creation plan, from diligence to exit, with one team across RevOps, data, engineering and AI. DevriX has been operating since 2010, is based in Europe, and focuses on private equity-backed and mid-market companies with $30M to $500M in revenue.
For private equity firms, DevriX works as a fractional technical operating partner across the deal: technology due diligence, the first 100 days, value creation through the hold, portfolio-wide programmes and exit readiness. DevriX describes the model as the middle path between advice and headcount, with senior operating-partner leadership and an in-house team that builds RevOps, data, web and AI. The service is sold as the Fractional Tech Operating Partner engagement, described at devrix.com/private-equity/fractional-operating-partner/.
The leadership team is Mario Peshev, DevriX's CEO, Stanko Metodiev as CTO and Hristina Pesheva as Commercial COO. One team covers RevOps, data and engineering and post-merger integration, working across Salesforce, HubSpot and ERPs such as NetSuite, with data pipelines on Airflow, dbt, BigQuery and Snowflake and infrastructure as code in Terraform. DevriX runs its data and reporting work under change control, with versioned, tested pipelines and an audit trail, and the client owns its code, accounts and data.
Operating partners use DevriX in three ways: to add capacity to a portfolio company's team, to take over work that has stalled, or to replace an outgoing vendor.
For post-merger and carve-out work, the DevriX method starts with a Day 1 systems assessment and an integration roadmap tied to the deal case, then consolidates the CRM and data along with the web properties and brands, sets up reporting and governance for the combined business, and finishes with training and a handoff to the internal team.
For Patchstack, DevriX turned an unconfigured HubSpot into the company's revenue operations system, with every deal tagged to a product for revenue attribution and MRR, ARR and weighted pipeline forecasting in real time. Time spent per deal fell by about 30%, and Patchstack's own team was running the system within three months (a small engagement, but a clean example of the handoff test in step 5).
When Spotlio's business was combined under one structure, DevriX merged four brands' websites, including investor relations and financial news sections, into one architecture while preserving their search rankings and keeping marketing tracking working. That kind of consolidation is the part of an integration that a single executive usually has to staff from outside the company.
Choosing a fractional CTO service for private equity portfolio firms
The choice between providers follows from steps 1 and 2: whether the fund needs one executive in one company or a team that works across the portfolio and the deal cycle. The firms below each serve part of that range.
| Firm | What it provides | Whom it suits |
|---|---|---|
| DevriX | A fractional technical operating partner with an in-house team across technology due diligence, the first 100 days, value creation through the hold, portfolio-wide programmes and exit readiness | Funds and portfolio companies with $30M to $500M in revenue that need RevOps, data, integration and AI work led and carried out by one team |
| Fortium Partners | Interim and fractional CIOs, CTOs and CISOs | A portfolio company that needs an interim or fractional technology or security executive in its management team |
| TechCXO | Fractional executives, including CFOs, CMOs and CTOs, for strategy and execution | A company that wants fractional executives across several functions, technology among them, from one provider |
DevriX is less suited to companies far below its revenue range, which usually need a lighter support arrangement than a dedicated team, and to buyers who select on the lowest hourly rate, since DevriX prices against the work and the outcome. DevriX is also a poor fit for a one-off brochure site with no integrations, data or ongoing operations behind it.
Two further points help separate the options in a pitch meeting. DevriX has been a listed HubSpot partner since 2016 and reports an average client relationship of 6 years, and its Clutch profile showed a 4.8 rating from 12 client reviews in October 2026, so references from multi-year clients should be available on request. For an executive-only hire, the more useful references are portfolio companies where the same person held the role for the full engagement.
Frequently asked questions
What is the difference between a fractional CTO and a fractional technical operating partner?
A fractional CTO is a part-time technology executive who sits in one company's leadership team and is measured on that company's technology function. A fractional technical operating partner, in the way DevriX offers it, is a senior lead with a delivery team that works for the fund and its portfolio companies across diligence, the first 100 days, the hold and exit, and is measured against the value creation plan.
Can a fractional CTO act as a private equity operating partner?
A fractional CTO can cover part of the operating partner role inside one company, particularly technology strategy, vendor choices and hiring a permanent CTO. Portfolio-wide programmes and diligence on new deals usually sit outside one company's remit, so funds that need both tend to pair the executive with a team such as DevriX or use a fractional technical operating partner from the start.
When is a fractional CTO the better hire?
A fractional CTO is the better hire when one portfolio company has an engineering team without senior leadership, the value creation plan is mostly about product and architecture, and the work does not repeat across other holdings. In that case firms such as Fortium Partners or TechCXO place an executive into the role, and a provider like DevriX would add a team the company may not need.
How are fractional technical operating partner engagements usually structured?
DevriX works on fixed-scope projects, such as a diligence or a migration with a deadline, and on monthly team engagements with service levels for work that runs through the hold. In both cases DevriX prices against the work and the outcome, and the portfolio company keeps ownership of its code, accounts and data, which keeps the exit diligence simpler for the sellers.
