Who is Harris Computer?
Harris Computer, formally N. Harris Computer Corporation, is one of the six operating groups of Constellation Software, the Toronto listed serial acquirer of vertical market software companies. Harris is headquartered in Ottawa, Canada. Nigel Harris founded the company in 1976, and Constellation Software acquired it in 1996.
Harris is the oldest Constellation operating group and one of the most active software acquirers anywhere. The Harris website reports 277 acquired businesses, more than 15,000 employees, and over 165,300 customers across 26 verticals. Harris closed 19 acquisitions in 2025 alone, according to the company’s published year in review.
Jean Soucy became Harris Group CEO on June 1, 2024, after leading the Harris Public Sector group. Jeff Bender, Harris’s longtime CEO and a Constellation Software board director, moved into a newly created Executive Chairman role in which he oversees strategy and complex M&A transactions. A founder who receives outreach from Harris is dealing with one of the most experienced acquisition teams in vertical software.
Harris also executed the largest disclosed deal in Constellation’s history. In 2022 Harris acquired the Allscripts Hospitals and Large Physician Practices business for $670 million in cash plus an earnout of up to $30 million, then relaunched that unit as Altera Digital Health.
What kinds of companies does Harris Computer buy?
Harris buys vertical market software companies serving public sector, utilities, healthcare, schools, and insurance customers, plus a widening range of private sector niches. The common thread is mission critical software with recurring revenue and customers who rarely switch systems. Harris states that it acquires businesses, manages them using industry best practices, and holds them permanently; like every Constellation group, Harris does not resell what it buys.
Harris publishes its preferred business characteristics on its Being Acquired page. The published list describes a durable niche business, not a high growth startup.
| Criterion Harris publishes | What it signals for a founder |
|---|---|
| Mission critical enterprise software solutions | Harris pays for software customers cannot rip out, because switching costs protect maintenance revenue for decades. |
| Diversified customer base | Concentration above roughly 10 to 15 percent in one customer weakens a founder’s position in diligence with any serial acquirer. |
| Low customer attrition | Retention is the core input to Harris’s return model; gross retention above 90 percent is the profile Harris targets. |
| Leading or increasing market share | Harris prefers the number one or number two product in a narrow vertical over a small player in a broad market. |
| Fragmented competition | A fragmented vertical gives the acquired business room for follow-on acquisitions under Harris ownership. |
| Expansion potential | Geographic or product adjacencies let Harris grow the business without discounting the entry price for that growth. |
Deal size at Harris spans an unusually wide range. Harris buys businesses with a few million dollars of revenue and it bought a hospital software carve-out valued at $700 million including the earnout. Payment is cash at close in nearly all cases.
What has Harris Computer acquired?
Harris has completed more than 270 acquisitions since 1976, and the pace has accelerated: 19 closed in 2025. The vast majority of Harris purchase prices are never disclosed, because individual deals fall below the materiality thresholds that would force disclosure in Constellation Software’s filings. A founder should read any list of Harris deals as a record of volume, not of pricing.
| Acquired business | Year | Vertical | Disclosed terms |
|---|---|---|---|
| Allscripts Hospitals and Large Physician Practices (now Altera Digital Health) | 2022 | Healthcare, hospital EHR | $670M cash plus up to $30M earnout |
| Acceo Solutions | 2018 | Payments and municipal software | Undisclosed |
| Commerce Decisions | 2020 | Public sector procurement | Undisclosed |
| MEDHOST | 2024 | Healthcare, community hospital systems | Undisclosed |
| SirsiDynix | 2025 | Library management software | Undisclosed |
| GlobalMeet | 2025 | Virtual events and communications | Undisclosed |
| Eloquant | 2025 | Customer experience software, France | Undisclosed |
| TECVIA Holding | 2025 | Industrial software, Germany | Undisclosed |
The Allscripts transaction announced in March 2022 and closed in May 2022 brought Sunrise, Paragon, TouchWorks, dbMotion, STAR, HealthQuest, and Opal into Harris. Harris rebranded the unit as Altera Digital Health within weeks of closing, which shows how quickly Harris integrates even its largest purchases into its named-business structure.
What does Harris Computer pay?
Harris pays cash at close and almost never publishes a price. The Allscripts deal is the rare real print at the operating group level: $670 million upfront plus an earnout capped at $30 million and tied to two years of post-close performance. Earnouts of that kind appear on Harris’s largest deals; small Harris acquisitions are typically structured as straight cash purchases.
Parent-level context matters because Harris underwrites deals the Constellation way. Investor analyses of Constellation Software have repeatedly cited entry prices around 0.8 to 1.0 times revenue for small vertical software acquisitions, and Constellation’s shareholder letters describe strict after-tax return hurdles that were relaxed only for very large transactions. Those figures are parent-level investor commentary, not Harris published pricing, and any specific company can trade above or below them.
The practical point for a founder is that a Harris opening number is built from Harris’s return requirement, not from what the market would pay. Windsor Drake measures the bilateral-vs-competitive gap at 15 to 25 percent of enterprise value across serial acquirer negotiations. Harris is a disciplined buyer that will walk away rather than outbid a competitive field, which is precisely why Harris works hard to keep negotiations bilateral.
How does Harris Computer source deals?
Harris runs a dedicated in-house M&A team that sources deals through direct founder outreach, and the company promises a response within 24 hours to inbound acquisition inquiries, with Michael Kim listed as the current contact. Constellation’s operating groups collectively track tens of thousands of vertical software companies in internal prospect databases, according to investor interviews with former Constellation executives.
Outreach from Harris often runs for years before a founder is ready to sell. A business development associate checks in every six or twelve months, builds a file on the company, and is positioned as the natural first call when the founder finally considers an exit. The email feels personal. The system behind it is industrial, and it exists to originate deals before a banker is hired.
What does an approach from Harris look like?
A Harris approach leads with permanence: the pitch is a forever home for the product, continuity for employees, no forced migration for customers, and cash at close. Speed and certainty are the stated advantages, and they are real. Harris has closed hundreds of deals and does not need financing contingencies.
The mechanics follow a standard sequence: an NDA, a financial information request, an indication of value, then a letter of intent with exclusivity. Serial acquirers commonly ask for 30 to 90 days of exclusivity; 30 to 45 days is the recommended counter. Roughly 1 in 3 signed LOIs fail to close on their original terms, so the number in the LOI is the ceiling, not the floor. A founder holding a live Harris offer should treat it as the start of a decision process, and the guidance at what to do with an unsolicited offer covers the first moves.
What happens to your company after Harris buys it?
Harris holds acquired businesses indefinitely and runs them as autonomous units under their own brands. Harris publishes commitments to retain and develop employees, to enhance products rather than force migrations, and to stay in its markets forever. Those statements come from Harris’s own acquisition pages and should be read as marketing to sellers, even where the operating record supports them.
Public accounts from acquired leadership are largely positive. MEDHOST leadership described the future with Harris as full of opportunity after the 2024 deal, and SirsiDynix ran customer webinars in January 2025 presenting the Harris acquisition as a stable new ownership era. Post-close life also includes the Constellation toolkit: benchmarking against sister businesses, margin and return-on-capital targets, and pressure to raise prices on maintenance contracts. Autonomy at Harris is real, and so are the metrics.
Who else competes with Harris for software companies?
Harris’s closest competitors are its own siblings. Volaris Group and Jonas Software run the same permanent-hold playbook from inside Constellation, and independent consolidators such as Valsoft and Banyan Software pitch a nearly identical forever-home story. In healthcare IT at scale, financial sponsors such as Vista Equity Partners bid for the same assets Harris wants, so a healthcare software founder rarely faces a market with only one credible buyer.
Strategic acquirers inside each vertical add a further set of bidders. Utilities software attracts industrial buyers, public safety attracts defense-adjacent strategics, and education attracts scaled edtech platforms. The existence of these buyers is what a bilateral Harris negotiation quietly prices out.
What changes if you run a process instead of negotiating with Harris alone?
The Proprietary Discount is the gap between what a serial acquirer pays in an unbanked bilateral negotiation and what the same business clears in a competitive process, and Windsor Drake places that gap at 15 to 25 percent of enterprise value. Harris’s sourcing model is built to acquire companies before they hire advisors, because a proprietary deal is where a disciplined buyer’s pricing holds. Windsor Drake publishes its measurement methodology at The Windsor Drake Proprietary Discount Index.
A competitive process changes the arithmetic without excluding Harris. A Windsor Drake sell-side process opens with a buyer universe of 150 to 300 potential acquirers, and Constellation groups do participate in processes when the asset fits their model. A full process runs 6 to 10 months; a process run alongside a live offer runs 4 to 6 months. If Harris has already approached you, Windsor Drake’s Approach Response engagement is built for founders holding a live inbound offer.
Questions founders ask
Is Harris Computer the same as Constellation Software?
No. Harris Computer is one of six operating groups inside Constellation Software, the Toronto listed consolidator. Harris operates independently, runs its own M&A team, and reports into Constellation, which acquired the original N. Harris Computer Corporation in 1996.
Does Harris Computer ever sell the companies it buys?
No. Harris follows the Constellation model of buying and holding software businesses indefinitely. Harris has completed more than 270 acquisitions since 1976 and markets itself to sellers as a permanent home rather than a financial owner with an exit timeline.
How much did Harris pay for the Allscripts hospital business?
Harris paid $670 million in cash at closing plus an earnout of up to $30 million tied to two years of performance, a total of up to $700 million. The deal was announced in March 2022, closed in May 2022, and the unit was rebranded Altera Digital Health.
Who runs Harris Computer?
Jean Soucy has been Harris Group CEO since June 1, 2024. Jeff Bender, who led Harris for roughly two decades, became Executive Chairman and continues to oversee strategy and complex M&A transactions while serving on Constellation Software’s board.
Does Harris Computer pay in cash?
Yes. Harris advertises cash payment at close, and small and mid-sized Harris acquisitions are typically all-cash. Earnouts appear on Harris’s largest deals, such as the $30 million performance earnout in the Allscripts transaction.
What multiple will Harris Computer pay for my software company?
Harris does not publish multiples. Investor analyses of parent Constellation Software have cited roughly 0.8 to 1.0 times revenue for small vertical software deals, which is commentary, not Harris pricing. A competitive process, not a benchmark, sets the real ceiling, and the bilateral gap runs 15 to 25 percent of enterprise value.
Should I respond to an acquisition email from Harris Computer?
Not with financials. Harris outreach is systematic and designed to start a bilateral negotiation on Harris’s terms. Acknowledge the interest, decline to share information before an NDA, and decide first whether you want a competitive process, because that choice moves value more than any reply.
