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. The private equity-backed platform hunting for add-ons has become one of the most active buyer personas in mid-market software M&A.
The numbers reflect that shift. Platform deals fell to 41% of private equity software deal value in 2026, their lowest share in at least a decade, while add-ons expanded to roughly 45% and more than doubled their share year over year.
For a founder running a sell-side process, the direct consequence is that the acquirer target list needs to be built and approached differently to create demand and competitive tension around the asset. The relevant PE buyer universe is increasingly made up of portfolio companies looking for product, geographic or vertical expansion, rather than funds underwriting a new standalone platform. Traditional strategic and financial acquirers still matter and still belong in a well-run process, but the center of gravity has shifted toward PE-backed buyers.
This article is for founders of $5M to $100M ARR software companies who should expect private equity to be part of the conversation, or who are actively weighing that route. It covers how sponsors evaluate software, how a private equity sale runs in practice, why an advisor’s sponsor relationships can affect the outcome, and which firms founders should consider when selling software to private equity.
How private equity buyers evaluate software in 2026
Selling software to private equity means running a process toward financial sponsors who underwrite on cash-flow durability, leverage capacity, and an eventual exit window. That lens differs from a strategic acquirer’s, though it is not opposed to synergy. The most active sponsors today buy through platforms they already own, and those platforms want a complementary product, a new vertical, a geography, or a customer base that compounds with what they hold.
The headline numbers look discouraging on first read. Private equity deal value in software fell 65.7% year over year in the second quarter of 2026 as investors tested how quickly AI would disrupt legacy vendors. That figure describes large, financing-dependent platform transactions. Beneath it, add-on activity held its ground, and that is the segment most mid-market founders actually sell into.
Two terms carry most of the weight in a sponsor’s acquisition thesis:
- Platform acquisition: a sponsor buys a company to anchor a new investment thesis, usually within a specific vertical, workflow, or market category. The company becomes the base that later acquisitions attach to.
- Add-on acquisition: a sponsor, through a portfolio company it already owns, acquires a smaller business to extend product, geography, customer base, or capability. Most mid-market software exits now fall into this category.
The distinction decides how a process should be run. An add-on buyer is not shopping for a category, it is filling a gap it has already defined. Winning that buyer means knowing which platforms hold active vertical mandates, where they sit in their fund cycle, and what thesis they are buying against. That is a relationship and data problem rather than a volume problem.
Leverage sets the ceiling on the rest. Sponsor bids are financed by private credit, and underwriting policy effectively caps 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 buyer conviction does. An advisor who reads that stack can tell which buyers have room to stretch and which do not.
Which private equity buyers are active, by vertical
Sponsor demand in software is not evenly spread, and a founder gains little from knowing that private equity is active in general. What matters is whether buyers are active for a company like theirs. L40° maps that demand at the vertical level across a network of 172 private equity buyers and 5,780 portfolio companies, spanning 28 mapped verticals.
The pattern is consistent. Buyers pay up for systems that are mission-critical, regulated, or transaction-linked, and they discount software an AI agent could plausibly replicate.
Sponsor exit pressure is feeding that demand. 34% of private equity portfolio companies globally have now been held for more than five years, up from 28% a year earlier. Ageing portfolios push general partners to return capital, and platforms carrying that pressure need to show growth before their own exit.
Acquisition is the fastest route to that growth. Nearly 4,600 US portfolio companies now sit past the five-year mark, which keeps add-on appetite alive even through quiet quarters for large buyouts. For a founder, that is the useful read on 2026: quiet headlines, active buyers, concentrated in specific verticals.
How to sell a software company to private equity
A private equity sale runs through the same four phases as any structured sell-side process. What changes is how each phase is calibrated around platform fit, add-on logic, fund timing, and investment thesis. At L40°, every mandate follows the same construct, The L40° Sell-Side Process:
- Prepare & Position: build the data room, CIM, and forecasts around what a sponsor stress-tests. The financial story and the AI-defensibility narrative have to hold up against a three-to-four-year exit thesis, not just a current-year growth story.
- Targeted Outreach: map active platforms and their vertical mandates, then approach each buyer with a thesis-aligned narrative rather than a broad teaser blast. The objective is not the largest possible buyer universe. It is getting the blind teaser into rooms where a credible acquisition rationale already exists.
- Drive Negotiations: run parallel platform conversations to create competitive tension, and negotiate structure alongside price. In sponsor deals, earnout, rollover and escrow terms often move the net outcome more than the headline multiple does.
- Execute & Close: control diligence and protect founder leverage through to signing. A tightly run process is what stops a buyer chipping at terms agreed at LOI.
The outreach width is a deliberate choice, defined on a case-by-case basis depending on the best strategy to go to market, not a default. Most processes benefit from a curated mix of financial sponsors, holding companies, PE-backed platforms and, selectively, strategic acquirers, because tension needs more than one credible bidder. How broad the list runs depends on the asset, the thesis, the founder’s preference, and where realistic demand is most likely to emerge.
On timing, a structured process typically runs six to nine months from engagement to cash in, with preparation ahead of that. Founders who compress the preparation phase usually pay for it in diligence.
Why advisor-to-sponsor relationships change the outcome
In an add-on-dominated market, the decisive asset is current knowledge of which platforms are buying, who runs them, in which verticals, and where they sit in their fund cycle. A static buyer list goes stale within months, but a current one shows who holds fresh capital, an open mandate, and a thesis a given company completes.
Instead of a wide sweep, the work is identifying which platforms have active vertical mandates that fit the business, then engaging them with a narrative built around what they are already trying to buy. That knowledge comes from continuous market contact, not from a database pulled on request.
A disciplined sell-side process is run by an advisor who knows that the right, targeted sponsor set converts specific platform demand into leverage. Without that precision, real demand may stay undiscovered or underdeveloped.
Best firms to sell software to private equity
The best firm for a private-equity-bound software exit is not always the largest brand, but the one that understands the equity story, knows where the relevant buyers are, and can turn that access into a competitive process. Five characteristics tend to differentiate the strongest firms in this space:
- Live sponsor 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, net revenue retention, 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 sponsor deal structure: earnouts, equity rollover, escrow and leverage, not just headline price.
The firms below are among those founders, management teams and investors are likely to evaluate when selling a mid-market software company to private equity..
1. L40°
Best fit: Mid-market software and AI companies seeking a competitive, cross-border sell-side process.
L40° is a boutique M&A advisory firm specializing in sell-side, mid-market transactions for software and AI companies. The firm works with founder-led, venture-backed and investor-backed businesses, typically where the likely acquirers span private equity funds, PE-backed platforms and strategic buyers.

Best fit:U.S.-focused software companies looking for a specialist technology M&A advisor.
Software Equity Group is a long-established software M&A boutique with significant experience across SaaS and recurring-revenue businesses. Its focus is predominantly U.S. software sell-side, making it one of the specialist firms founders are likely to encounter when comparing advisors for a private equity exit.
3. Corum Group
Best fit: Privately held software companies where broad international buyer outreach is a priority.
Corum Group has advised technology companies for several decades and operates across multiple international markets. Its model is built around broad buyer coverage across strategic and financial acquirers, and it is commonly considered by privately held software businesses exploring a sale.
4. Alantra
Best fit: Larger technology companies with a European angle.
Alantra is a global investment bank with an established technology practice and broad relationships across European private equity. It is typically more relevant for larger, institutionally oriented processes where international sponsor coverage and a broader investment banking platform are important.
5. Drake Star
Best fit: Growth-stage technology companies running larger international processes.
Drake Star is a technology-focused investment bank with offices across North America and Europe. The firm advises across software and digital sectors and is often considered for larger venture-backed or growth-stage transactions where both financial and strategic buyers may be relevant.
6. Houlihan Lokey
Best fit: Larger software transactions with institutional shareholders and major private equity buyers.
Houlihan Lokey is one of the largest global mid-market M&A advisors, with extensive sponsor relationships and a significant technology practice. It is most relevant at the upper end of the market, where transaction size and complexity justify the resources of a larger investment banking platform.
Overall, the right advisor depends on the type of process you are likely to run. Company size, ownership, geography and the expected buyer type all matter, as does the level of senior attention the mandate will receive. A larger bank may be the better fit for an institutional-scale transaction, while a specialist boutique can be more relevant where sector knowledge, partner involvement and targeted buyer access are central to the outcome.
How to choose: questions to ask a private equity focused advisor
If a sponsor buyer is likely, these five questions surface whether an advisor is built for that process or improvising it:
- Which platforms have you placed assets with in 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, including earnout, rollover and escrow, rather than price alone?
The takeaway
Private equity has become a more important part of the buyer landscape for mid-market software, but reaching sponsors is not the same as creating competition among them. The outcome depends on identifying which funds and portfolio companies have a real acquisition rationale, positioning the company appropriately for those buyers, and managing the process tightly enough to preserve leverage through diligence and negotiations.
That makes advisor selection part of the exit strategy itself. For a $5M to $100M revenue software company, the question is not simply which firm has the largest network, but which team understands the business, knows the relevant buyers and has the senior attention to run the process well.
