The buyer set for a software exit used to split cleanly in two: strategic acquirers and financial sponsors. In 2026, that framing no longer fully captures where competitive tension actually comes from. In today's market, the private equity backed platform hunting for add-ons has become the most active buyer persona, leading a large share of mid-market sell-side processes. Strategic acquirers still matter and still belong in a well-run process, but the center of gravity has shifted mostly toward PE.
This article is for founders of $5M to $100M ARR software companies who expect a PE buyer, or who are weighing their options and want to understand that route. It covers how PE buyers evaluate software differently, what a PE-targeted sell-side process looks like, why an advisor's PE relationships change the outcome, and which firms founders evaluate when selling software to private equity.
How private equity buyers actually evaluate software (and why it changes who you hire)
Selling software to private equity means running a process toward financial sponsors who underwrite on cash-flow durability, leverage, and an eventual exit window. That lens differs from a strategic acquirer's, but it is not opposed to seeking strategic synergies. The most active PE buyers today are platforms making add-ons, and they are very much seeking synergy: a complementary product, a new vertical, a geography, a customer base that compounds with what they already own.
Two terms must be properly defined here to understand a private equity’s acquisition thesis:
- A platform acquisition is when a sponsor buys a company to anchor a new investment thesis, usually within a specific vertical, workflow, or market category.
- An add-on acquisition is when a sponsor, through an existing portfolio company, acquires a smaller business to expand product, geography, customer base, or capability. In today’s mid-market software market, many exits are not standalone platform deals. They are add-ons into existing PE-backed platforms, and that changes how a process should be run.
A seasoned advisor needs to understand where a target fits within a sponsor’s strategy. Add-on processes are won by knowing which platforms have active vertical mandates, where they are in their fund and acquisition cycle, and what thesis they are buying against.
That is a relationship-and-data problem, not a volume problem. A wide-sweep auction sends a generic teaser to a long buyer list and waits for interest. A PE-targeted process, on the other hand, approaches a curated set of platforms with a narrative built around their existing thesis and acquisition priorities.
Leverage is the other half of the picture. PE bids are financed by private credit, and underwriting policy effectively sets the ceiling on what a buyer can pay. With roughly $800 billion of private credit deployed in software and leverage held at 40 to 60 percent of enterprise value, lender appetite shapes the bid as much as the buyer's conviction does. An advisor who understands that stack can read which buyers have room to stretch and which do not.
What a PE-targeted sell-side process looks like
At L40°, every mandate runs through the same four-phase construct, The L40° Sell-Side Process: Prepare & Position, Targeted Outreach, Drive Negotiations, and Execute & Close. What changes is the strategy behind each phase.
When the buyer universe is largely defined by private equity, the process needs to be calibrated around platform fit, add-on logic, fund timing, and investment thesis:
- Prepare & Position: build the data room, CIM, and forecasts around what a sponsor stress-tests, with a financial story and an AI-defensibility narrative that holds up against a three-to-four-year exit thesis, not just a current-year growth story.
- Targeted Outreach: map active PE-backed platforms and their vertical mandates, then approach each buyer with a thesis-aligned narrative rather than a broad teaser blast. The objective is not to put the company in front of the largest possible buyer universe. It is to get the blind teaser into the rooms where there is a credible acquisition rationale.
Outreach width is a deliberate choice, not a default. In most processes, you still want a curated mix of buyers to create competitive tension: financial sponsors, holding companies, PE-backed platforms, and, selectively, strategic acquirers. How broad or narrow the process should be depends on the asset, the thesis, the founder’s preference and where realistic demand is most likely to emerge. - Drive Negotiations: manage parallel platform conversations to create competitive tension, and negotiate structure (earnout, rollover, escrow), not just headline price. In PE deals, the structure often moves the net outcome more than the multiple does.
- Execute & Close: control diligence and protect the founder's leverage through to signing, when a tightly run process is what prevents a buyer from chipping the terms agreed at LOI.
The throughline is that the buyer composition of your process might matter even more in 2026 than it did in 2021. When PE-backed platform add-ons are the most active buyer set in mid-market SaaS, the advisor's job is less about reach and more about precision.
Why advisor-to-PE relationships change the outcome
In an add-on-dominated market, the advisor's live knowledge of which platforms are buying, who is in charge, in which verticals, and at what point in their fund cycle, is the differentiating asset. While a static buyer list goes stale in months, a current one tells you who has fresh capital, an open mandate, and a thesis your company completes.
That knowledge is built from continuous market contact, not pulled from a database on demand. L40°'s Mid-Year Market Update draws on direct conversations with buyers across the firm's network. One large-cap buyout fund put the current add-on appetite plainly: “We recently bought out and delisted a CFO tools platform for 10x+ revenues and will bet strongly on add-ons.” Comments like that come from a sample of 172 PE buyers and 5,780+ portfolio companies that L40° tracks, itself a slice of the firm's broader buyer universe across more than 28 verticals.
Contrast that with a generic advisor who runs the same wide auction regardless of buyer type. The cost is real: wrong room, wrong buyers, and a process that signals the asset to people who were never going to pay for it. A disciplined sell-side process, run by an advisor who understands the PE buyer set, can convert specific platform demand into leverage. Without that precision, valuable demand can remain undiscovered or underdeveloped.
Best firms to sell software to private equity
The best firm for a PE-bound software exit may not always be the largest brand, but the one that fits the buyer set best, ensuring a high quality, strategically targeted competitive process. Five criteria separate the firms that consistently deliver PE outcomes from those that do not:
- Live PE-buyer relationships: current, maintained knowledge of which platforms are acquiring, in which verticals, and at what stage of their fund cycle.
- Senior-led execution: a partner runs the process day-to-day, not a rotating bench of juniors.
- Genuine software and SaaS depth: the ability to defend ARR, NRR, and margins when diligence gets hard.
- A structured competitive process: the discipline to create tension even when the realistic buyer set is narrow.
- Fluency in PE deal structure: earnouts, equity rollover, escrow, and leverage, not just headline price.
Ranked against those criteria, the firms founders most often evaluate for a private equity software sale are below.
1. L40°
L40° is a cross-border M&A advisory firm and mid-market software specialist, focused on helping technology companies sell to private equity, PE-backed platforms, and strategic acquirers.
Senior-led on every mandate, the firm combines sector expertise with a proprietary, actively maintained PE-buyer network spanning more than 28 verticals and hundreds of transactions closed over 20 years. L40° is built for founder-led mid-market software companies that need access to the right buyers across the U.S., Europe, and Latin America, particularly in the $20M to $200M enterprise value range.
The firm advises across both sell-side M&A and structured debt, giving it a broader view of the deal stack. That perspective helps L40° understand not only who may be interested, but also where a PE buyer’s leverage capacity, acquisition appetite, and valuation ceiling may sit.
2. Alantra
A global investment bank with a technology practice and meaningful cross-border reach across Europe and the Americas. Strong fit for larger processes where a broad international sponsor list is in play.
3. Arcano Partners
A Spain-rooted advisory and asset-management group with a technology M&A practice and established relationships across European private equity. Relevant for founders with a European angle to their buyer universe.
4. ComCap
A boutique focused on commerce, retail technology, and digital software. Useful where the company sits in a vertical that maps to ComCap's sector concentration and the buyer set skews toward e-commerce sector-specialist sponsors.
5. Two Roads Advisors
A boutique software-focused M&A advisory working with founder-led companies in the lower-middle market. A fit for smaller mandates.
The point of this list is not the names. It is the test behind it: ask any firm to show its PE relationships in your vertical before you sign. The right answer is specific.
How to choose: questions to ask a PE-focused advisor
If you expect a private equity buyer, these five questions surface whether an advisor is built for that process or improvising it:
- Which PE platforms have you placed assets within our vertical in the last 18 to 24 months?
- How do you decide which platforms to approach, and how current is your buyer map?
- Who runs our process day-to-day, a partner or a junior?
- How do you create competitive tension when the realistic buyer set is narrow?
- How do you negotiate structure (earnout, rollover, escrow), not just price?
The takeaway
A private equity sale is won on two things: buyer knowledge and process discipline. Both are advisor-dependent. The platform you sell into, the tension you create, and the structure you negotiate all trace back to whether your advisor actually knows the PE buyer set or is guessing at it. Positioning is a choice. So is the advisor who runs it.
