For portfolio companies.
European technology leadership that operates within investor governance, not despite it.
Running technology in a European portfolio company is not the same as running technology anywhere else -- and it is certainly not the same as running technology in a US-domiciled business. There is a value creation plan with milestones that tie to exit. There is an operating partner, often based in New York or Boston, who needs visibility without micromanagement across a five-hour time gap. There is a board that expects technology progress translated into commercial language. And there is a local team operating inside European employment law, GDPR obligations, and a talent market with its own dynamics.
We work exclusively with PE and VC-backed businesses, and our partners have operated inside these structures from London, Amsterdam, Berlin, and Dublin -- reporting to US investors, aligning roadmaps to hold periods, and building technology functions that withstand buyer scrutiny when the time comes. With over 25 experienced CTOs and CPOs on our bench, we have the capacity and sector breadth to match the right leader to your specific European challenge. For a detailed look at how technology creates and protects value through the hold period, see our article on unlocking technology value in private equity.
Your European CTO just left?
Partner operational within a week
We maintain a bench of 25+ experienced CTOs across the UK and Europe. When a CTO departs, we mobilize fast -- no transatlantic lag, no cultural mismatch.
Team stabilized within 30 days
Our Rational Start methodology assesses the real state of things, addresses flight risk, and delivers a clear roadmap -- all in the first month, with full visibility for your US team.
Permanent hire or structured handover
We build capability and design ourselves out. Whether that means recruiting your next European CTO or extending, the goal is always independence.
What makes working with us different in a cross-border PE context
Dual Reporting Model
We report operationally to the European CEO and strategically to the US operating partner. Both get honest, independent updates -- no surprises at the next board meeting, no translation layer required.
Value Creation Alignment
Every technology decision traces back to the value creation plan. We prioritize what drives measurable value within the hold period, accounting for European market dynamics and exit conditions.
IC-Ready Reporting
Board packs that connect engineering progress to EBITDA impact. Written for investors, not engineers -- and calibrated for the expectations of US institutional buyers.
European Regulatory Fluency
GDPR, NIS2, AI Act, local employment law. We know the compliance landscape your portfolio companies operate in, and we factor it into every architecture and process recommendation.
Our services for European portfolio companies
Fractional CTO
Experienced technology leadership embedded 2-4 days per week. Strategy, team management, and board-level communication -- with dual reporting built in and European context native to the role.
Technology Audit
Independent assessment across the Five Pillars. Identifies what a buyer's DD would find -- including European regulatory exposure -- and quantifies remediation costs for the value creation plan.
Exit Preparation
We assess your European technology organization the way a US or European buyer would, then build the remediation plan that protects valuation. Start 18 months before sale.
CTO Recruitment
When the time is right for a permanent hire, we define the role, screen candidates against PE-specific criteria within the European talent market, and manage the transition through our Rational Closedown.
We help European portfolio companies build the technology capabilities that drive growth and valuation
Technology Strategy
Align the technology roadmap with the value creation plan and investor expectations -- shaped by European market realities, not a US-centric template.
Team Development
Build, structure, and professionalize the engineering function within European employment norms. Address key-person dependencies before they become buyer leverage.
Operational Excellence
Put in place the processes and practices that improve delivery cadence and reduce risk -- including the compliance and data governance obligations European companies carry.
Exit Preparation
Ensure technology withstands buyer scrutiny from US and European acquirers alike. Documentation, architecture narrative, team structure, and remediation of the issues DD will find.
