Fractional CTO for Private Equity

A senior operator in the CTO seat for the hold

A value creation advisor and operator in the CTO seat of a portfolio company, on a monthly retainer, accountable to the value-creation plan and the number the sponsor is underwriting.

Led by an operator who has founded six companies, exited two, acquired 40+ businesses, and advised over 500 since 2010.

The gap between a plan and a full-time hire

A value-creation plan often needs senior technical leadership before the company is ready, or able, to hire it. A full-time CTO search takes months, costs a package, and frequently lands the wrong person for the stage the business is actually in.

In the meantime the roadmap drifts, cloud spend creeps, the best engineers get nervous, and the board gets status updates instead of decisions. The cost is not a line item. It is a quarter of the hold spent going sideways.

A fractional seat closes that gap. It puts an operator who has done the job into the room now, accountable to a number, for the part of the week the company actually needs, without the search, the package, or the risk of a mis-hire.

When a portfolio company needs one

A full hire is slow and expensive. A fractional seat puts senior judgment in the room now.

What the seat covers

• Technical strategy. The roadmap tied to EBITDA, the build-versus-buy calls, and the platform decisions that carry cost through the hold.
• The engineering org. Structure, hiring, key-person risk, and the small number of roles that actually move the outcome.
• Vendor and spend. Cloud, tooling, and vendor decisions, and the technical debt that quietly caps the multiple at exit.
• Delivery discipline. A cadence that ships, with the roadmap turned into outcomes the team owns rather than a backlog.
• Board-ready reporting. A clear read the sponsor can act on, translating engineering reality into the language of the investment.

How the retainer works

Why a fractional seat beats a rushed hire

A mis-hire at the CTO level in a portfolio company is one of the more expensive mistakes in a hold: months lost to the search, a package committed, and a reset when it does not work. A fractional seat removes that risk. You get senior judgment immediately, and the arrangement flexes as the company grows into a full-time role, or does not.

Because the seat is held by an operator who has built and exited companies rather than a career manager, the decisions are made through the lens of the deal: the multiple, the hold, and the exit, not the size of the engineering team. The incentive is the outcome, not empire-building.

The seat is held by someone who has founded six companies, exited two, and built a 40-person firm managing $1.45B in GMV. This is technical leadership from an operator who has carried a number, not a consultant passing through.

Advisory, not implementation

This engagement carries no obligation to buy the build. Growth Shuttle advises. DevriX builds. They are separate businesses.

That separation is the safeguard. If the advice existed to sell an implementation, it would be worthless to the sponsor reading it. Here the only incentive is to be right. You can take the advisor alone, the builders alone, or both.

Who holds the seat

The work is led by Mario Peshev, a value creation advisor to private equity firms and an active operator. He has founded six companies, exited two, acquired and integrated more than 40 businesses and digital properties, and advised over 500 companies since 2010. He is also the founder of DevriX, a 40-person firm that builds technology, data, and revenue systems, with $1.45B in GMV under management, and he angel-invests in early-stage founders. Two decades in and around engineering organisations means the leadership is hands-on, not advisory-at-a-distance. Advisory and training work spans VMware, SAP, CERN, and Saudi Aramco, with coverage in Forbes, BBC, Inc, and Entrepreneur.
