When to Call Us.

The problems we find in European portfolio companies have almost always been festering for months. The CTO departure was the symptom, not the cause. Architectural debt, key-person dependencies, GDPR exposure, absent security practices. These accumulate quietly until something breaks. And when it breaks -- or surfaces during a buyer's due diligence -- the cost of fixing it dwarfs the cost of preventing it.

If you recognize your situation below, the conversation is worth having. If you are not sure, that is fine too. We will tell you honestly whether we can help.

Investment and Acquisition Moments

Acquiring a European Technology Business

You have identified a UK or European target. The commercial case is compelling. The management team is impressive. But how confident are you in the technology -- assessed by someone who understands the regulatory environment, the talent market, and the engineering culture your target operates in?

A US-based technology advisor assessing a European business will check the right boxes. They may miss the GDPR data architecture decisions that carry material liability. They may underestimate the complexity of complying with NIS2 in a critical infrastructure business, or the employment law constraints that make certain restructuring plans harder to execute than they appear on paper.

What we do. We conduct technology due diligence with European context native to the assessment -- not bolted on. Our partners have built and operated technology businesses inside these markets. We know where to look and what questions reveal the reality behind the presentation.

Post-Acquisition: Technology Integration Is Harder Than Expected

The deal is done. Now you face integrating two technology platforms, two engineering teams, two sets of processes -- and potentially bridging a US management team with a European technology organization. The cultural and regulatory dimensions make this harder than a domestic acquisition.

Without help. Integration timelines slip. The best engineers from the acquired company leave because they see chaos, not opportunity. GDPR obligations complicate data consolidation in ways nobody anticipated during diligence. The synergies that justified the acquisition do not materialize.

What we do. We provide on-the-ground technology leadership to manage the integration from the European side: working with both organizations, navigating the regulatory constraints, and reporting clearly to the US operating partner throughout.

Pre-Deal Technology Due Diligence

You are about to invest significant capital. Is the platform genuinely scalable or a well-presented front end with manual processes behind it? Will the architecture support the growth the investment thesis depends upon? And does the technology organization carry regulatory risk that would affect the deal or the hold period?

Without help. You make investment decisions on incomplete information. Risks a European-literate technology assessment would have identified become surprises twelve months into the hold period, eroding returns and consuming management attention.

What we do. We assess technology organizations for US investors across the UK and European landscape. Our methodology is stage-appropriate and market-aware. We assess whether the technology organization can support the growth the investment thesis requires -- in the market where it actually operates.

Operational Moments

Your European CTO Just Left

Our most common entry point for US investors with European portfolio companies. The CTO departs and the CEO suddenly realizes there is no clear picture of the technology landscape. The team knows their own corners but nobody has the full view. Decisions stall. The US operating partner asks questions nobody in Europe can answer. Recruitment takes four to six months, and in the meantime the technology function drifts. We have written a detailed guide to navigating this moment: Your CTO Just Left: What Now?

Without help. The team fragments. Your strongest engineers, sensing a lack of direction, start updating their resumes. Architecture decisions get deferred or made by committee. The six-month gap between CTOs becomes a period of regression that the new CTO will spend their first year undoing.

What we do. Stabilize the team, assess the landscape, build a 90-day plan, and create the conditions for a successful permanent hire in the local market. We have managed this transition for companies from 8-person startups to 180-person engineering organizations across the UK and Europe.

Your European CTO Is Leaving, But It Is Not a Crisis

Sometimes the transition is planned. Your CTO has given notice, the relationship is good, and there is time to do this properly. The challenge is capturing institutional knowledge before it walks out the door, maintaining team momentum during the gap, and defining what the next CTO actually needs to be -- including whether to hire locally or internationally.

Without help. The outgoing CTO writes a handover document nobody reads. The team drifts for three months. The new CTO arrives and spends six months learning what the previous one knew.

What we do. We embed alongside the departing CTO to capture knowledge systematically. We maintain operational leadership during the search. We help define the permanent CTO brief based on where the company is going and what the European market can realistically supply. And we manage the transition from ourselves to the incoming hire. Our Rational Closedown methodology was built for exactly this.

Strategic Moments

Preparing a European Asset for Exit

A buyer's technology DD will examine architecture, team, processes, security posture, and infrastructure through a rigorous lens -- and a buyer with a US-centric perspective may apply standards that do not account for European market norms. We know what both US and European buyers look for, because we conduct assessments for both.

Without help. Red flags appear in the buyer's DD report. These become negotiating leverage, chipping away at valuation, introducing earn-out conditions, or killing the deal entirely.

Timing matters. Eighteen months before exit is ideal. Six months is tight. Three months is crisis mode, and some issues simply cannot be fixed in that window.

Portfolio-Wide Technology Oversight Across European Assets

For PE and VC firms with multiple European portfolio companies, the challenge is visibility across the portfolio from a US base. Which companies have technology risks that could affect returns? Where are the opportunities for improvement? How do you provide effective technology governance without building an internal European team?

Without help. Technology issues surface as surprises during hold-period reviews or exit preparation. Cross-portfolio learning does not happen. Each company makes the same mistakes independently.

What we do. We provide portfolio-wide technology advisory with consistent methodology and European market knowledge. A standing relationship means you always have on-the-ground coverage without the overhead of an internal European technology team.

Major Platform Decision: Rebuild, Refactor, or Replace

One of the highest-stakes choices a technology organization makes. In a European context, the trade-offs carry additional dimensions: vendor lock-in with US hyperscalers may create data sovereignty complications. A rebuild may require navigating EU procurement rules. The talent to execute is subject to European employment law.

Without help. The decision is made on engineering preference, not business strategy. Nobody has the technical depth and commercial objectivity -- nor the European market context -- to evaluate the trade-offs properly.

What we do. Impartial assessment against your business context, growth trajectory, resource constraints, and the regulatory environment. Honest trade-off analysis for the board, calibrated for the expectations of both the US operating partner and the European management team.
