For many European software founders, some of the strongest interest in a sale may come from across the Atlantic. The US arguably holds the deepest, most liquid pool of mid-market software buyers, strategic and financial, and much of the capital chasing these assets. That does not mean a US buyer will automatically pay more than a European one. It means including qualified US buyers usually creates more demand, and more demand lets a tech company run a more competitive sale.
A Europe-to-US sale is not a domestic deal with a currency line added. Why a US buyer acquires a European software company, how the deal is structured, and where diligence gets harder all shift. Get the positioning wrong and a founder loses momentum or gives value back in re-trades. Get it right and a US-inclusive process becomes a lever on the outcome.
This article is written for founders of European B2B SaaS, tech, and AI companies in the $5M to $100M ARR range for whom a US buyer is a realistic acquirer. It covers why US buyers acquire European software, what they underwrite, how deals get structured, where diligence concentrates, and how to run the process from Europe. Enterprise value (EV), the measure of a company's total value to a buyer including equity and net debt, is the number every one of these decisions moves.
Why US buyers acquire European software companies
A strategic acquirer is an operating company that buys another business to strengthen its own product, market, or capabilities. US strategics acquire European software to enter or deepen a market, add a category or AI capability, or absorb a competitor. Private equity platforms buy for consolidation and reach, folding a target into a portfolio company as an add-on.
The US comes up so often because of scale, not generosity. It is where the most qualified mid-market software buyers and the most capital sit. Global buyout dry powder is roughly $1.3 trillion, with North America driving the most buyout deal value in 2025. US-Europe flows have been the strongest cross-regional corridor, accounting for 44% of the EMEA volumes in recent Goldman Sachs analysis. Limiting outreach to European buyers alone leaves that demand untapped.
- Strategic acquirers buy for fit: a product that opens a market, closes a capability gap, or removes a competitor. Their willingness to pay tracks how real the synergy is, not where the target is based.
- Private equity platforms buy for the thesis: a target that strengthens a portfolio company or anchors a new one. Platform fit, more than geography, sets their number. The distinction between the two, and why financial sponsors increasingly match or beat strategic multiples, matters more than the buyer's passport.
What US buyers underwrite, and what slows a deal down
US buyers do not underwrite a European company differently because it is European. They assess the same fundamentals any serious buyer does, then weigh a few factors specific to a target in a market new to them. What raises conviction is evidence, not currency.
- Raises conviction: a product with proven US traction or a credible path to it, which de-risks the operation by showing the market is real. Recurring revenue quality, net revenue retention, gross margin, clean IP, and defensible AI all support the case. A US foothold de-risks expansion, but it is evidence the market exists, not an automatic markup.
- Slows a deal down: single-market concentration with no expansion story, a messy IP chain across contractors and jurisdictions, and financials that cannot be reconciled to a standard the buyer's team recognizes. None lowers the quality of the business, but each adds friction, and friction in diligence is where value leaks.
The 2026 market rewards this. As AI has unsettled software valuations, buyers lean harder on EBITDA and cash-flow quality than revenue multiples alone. A European company that shows durable economics, cleanly, is easier to underwrite from either side of the Atlantic. The table below sets the two side by side.
Structure and terms in a Europe-to-US deal
An earnout is a portion of the price paid later, contingent on the business hitting agreed targets after close. Rollover equity is a stake the founder keeps in the acquiring or combined entity rather than cashing out in full. Both are common in European and US deals alike, not a US import. They bridge the gap between what a seller believes the business is worth and what a buyer will commit to today, and they appear wherever that gap needs bridging.
- Common structures: cash, earnout, rollover equity, and escrow or holdback, mixed to match the risk in the deal. When a buyer wants a founder aligned through a transition, or near-term performance is uncertain, more consideration moves into rollover and earnout. That reflects the company and the buyer's read of it, not a European or American preference.
- Cross-border specifics: these are the parts that actually change with a US buyer. FX exposure between signing and close, transfer pricing on IP that moves across jurisdictions, entity and tax structuring, and the US GAAP conversion a US acquirer needs for its reporting. Plan for them; they are not obstacles.
The key thing to keep in mind here is that the headline price is rarely the real economic outcome: structure decides it. Two offers at the same enterprise value can deliver very different results depending on how much is cash at close, how much is contingent, and how the LOI and reps and warranties allocate risk between the parties.
Diligence focus: IP, contracts, data, and financials
Diligence is where a Europe-to-US deal most often meets friction, so it helps to be precise about why. It is not that US buyers run a tougher process; serious buyers on both sides expect the same rigor. A few areas are structurally more complex for a European company bought by a US acquirer, and those are the ones to prepare first.
- IP ownership: US buyers confirm IP is cleanly assigned to the company across every contractor and jurisdiction. In Europe, employee and contractor IP assignment is not always automatic and varies by country, so gaps here are a frequent cause of delay. Documenting the chain before going to market removes the most common cross-border snag.
- Data and GDPR: a documented data-transfer and GDPR posture is a diligence workstream. A US buyer inheriting European data operations wants to see compliance is real and current.
- Financials: expect a US GAAP bridge or a quality-of-earnings review. IFRS-only books are not a problem in themselves, but if the numbers cannot be reconciled quickly, the timeline stretches, and a stretched timeline invites re-trades.
One point of accuracy: CFIUS, the US national-security review of foreign investment, is generally not triggered when a US buyer acquires a European target, since the acquirer is American. It matters mainly in the reverse direction. For multi-jurisdictional diligence and other corridors, see L40's cross-border M&A guide.
Positioning for a competitive process
The goal of a well-structured sell-side process is not to make the company attractive to a US buyer specifically. It is to prepare the business for any qualified acquirer, so that bringing US buyers into the process creates competitive tension rather than exposing gaps.
In practice, the preparation required to meet the expectations of a US acquirer will also strengthen the company’s position with European buyers. L40° frames this through the L40° Buyer-Readiness Check: four areas a European software company should have in place before running a process that includes US buyers.
- Financials that reconcile cleanly. Reporting should be consistent, well documented, and easy for a buyer’s diligence team to follow without extensive cleanup.
- A clean IP chain. Assignment should be documented across every contractor, employee, and jurisdiction.
- A documented data and GDPR posture. Policies and practices should be current, evidenced, and ready to hand over.
- A buyer universe wider than one inbound approach. There should be enough qualified demand across Europe and the US to run a competitive process rather than negotiate against a single bidder.
From there, the focus shifts to positioning and execution: understanding the quality of ARR, net revenue retention, gross margin, customer concentration, and the credibility of the growth and expansion story, then translating those findings into a compelling equity story, a buyer-specific outreach strategy, and diligence materials that withstand scrutiny.
This work sits within the broader structured sell-side process L40° runs for founders, following the same four core phases whether the buyer is based in Munich or New York.
Running the process from Europe
L40° advises European technology founders through sell-side processes involving both European and US buyers equally, on a case-by-case basis. Both buyers on either side of the ocean are professional and, hence, both expect the same diligence, and both respond to competition. What changes is mainly around logistics and reach.
- Build a wide, qualified buyer universe. A competitive process with several credible parties beats waiting on one inbound bidder. Including US buyers deepens that pool, so the process stays competitive through to close.
- Plan for the practical realities. Time-zone and travel load on management presentations, US-side legal and tax advisors alongside European counsel, and slightly longer alignment windows on cross-border points. These are coordination tasks, not deal-breakers, and an advisor running the process from inside Europe with live US-buyer relationships absorbs most of them.

What this means for founders
The founders who get the most out of a US-inclusive sale are not chasing a mythical American premium. They do the IP, data, and financial work early, then run a process wide enough to be competitive. A US buyer is not a shortcut to a higher number. A well-prepared company facing enough qualified demand produces the number, and preparation is the part a founder controls.
That is where a structured sell-side process earns its keep: qualified US buyers widen the pool, preparation makes the company ready for diligence, and a well-run process converts demand into leverage.
