Every few months, another familiar piece of business software changes hands - a human-resources platform, an email-security tool, a procurement system - and quietly gains the same new owner. The name on the deal is almost always the same: Thoma Bravo. It is not a household brand, and that is rather the point. The Chicago firm has built the largest software-focused investment business in the world by buying the unglamorous tools that companies cannot switch off, and it now manages roughly $180 billion doing it.
Thoma Bravo does not build software. It buys the companies that do - often taking them off the public markets entirely - then reshapes how they operate and grow. Over the past two decades the firm has acquired or invested in more than 580 software and technology businesses, representing over $300 billion in aggregate enterprise value. If you use enterprise software at work, there is a reasonable chance some of it sits, directly or indirectly, inside a Thoma Bravo fund.
01 / What it actually doesAn investor, not a builder
At its core, Thoma Bravo is a private equity firm. It raises money from institutional investors - pension funds, endowments, sovereign wealth funds - and pools it into a family of funds. It earns management fees on that committed capital and a share of the profits, known as carried interest, when its investments do well. What sets it apart is a narrow focus: software and technology, and very little else.
The firm's specialty is the take-private. It identifies an established, market-leading software company - frequently one trading publicly - and buys it outright, moving it off the stock market and out of the quarterly-earnings spotlight. Freed from public reporting pressure, the company can be restructured, refocused, and grown on a longer clock. Then, when the value has been built, Thoma Bravo sells it or takes it public again.
The firm invests based on company fundamentals rather than market cycles - buying and growing high-quality market leaders rather than pursuing distressed turnarounds.On the Thoma Bravo approach
02 / The playbookBuy, build, repeat
The strategy has a name that predates the firm: "buy-and-build." Co-founder Carl Thoma helped pioneer the industry-consolidation approach back in 1980 at his earlier firm, Golder Thoma (now GTCR). The idea is simple to describe and hard to execute - acquire a strong platform company, improve its operations, then add smaller complementary businesses on top to build scale. Thoma Bravo's contribution was to point that machine squarely at software, where recurring subscription revenue makes the math especially attractive.
The most striking thing about the portfolio is how much the deals rhyme. Rather than chase distressed turnarounds, the firm targets healthy leaders and compounds them. Repeatability, more than any single trade, is the moat.
03 / The obsessionA cybersecurity empire
If there is one sector where Thoma Bravo's ownership becomes almost startling, it is cybersecurity. The firm has been building a dedicated security thesis since 2008, on the logic that a more digital world needs more defense - and that security software, once embedded, is very hard to rip out. Over the years its security holdings have included some of the most recognizable names in the field.
Taken together, the security portfolio has generated an estimated $8 billion in combined revenue - a figure that would put it among the larger dedicated cybersecurity operations anywhere. It is a portfolio assembled one take-private at a time, and it explains why the firm is watched closely by anyone tracking who controls the plumbing of enterprise defense.
04 / The shopping listA record run of deals
The scale of the strategy has been on full display across 2025 and 2026. In a single stretch, Thoma Bravo agreed to buy Boeing's flight navigation business - including Jeppesen and ForeFlight - for about $10.6 billion, snapped up restaurant-software maker Olo for roughly $2 billion, and acquired customer-experience and automation company Verint for around $2 billion. Its largest move was the $12.3 billion take-private of human-capital-management leader Dayforce, completed in February 2026 at $70.00 per share.
Read as a list, it looks like a spending spree. Read as a map, it is something more deliberate - a sweep across the categories of software that businesses depend on to run, from payroll to navigation to customer service.
05 / What's nextAn AI upgrade, at portfolio scale
In 2026 the firm announced a strategic partnership with Google Cloud to accelerate AI adoption across its companies. The leverage there is unusual: when a single owner sits behind roughly 80 software businesses, an AI capability is not one product launch - it is a distribution channel that can be pushed across a whole catalog at once. The firm now frames much of this under a "Responsible Growth and Governance" umbrella covering cybersecurity, AI, operations, human capital and sustainability.

06 / The peopleFounders and philosophy
The firm was founded in 2008 by Carl Thoma and Orlando Bravo. Thoma brought the buy-and-build lineage; Bravo sharpened the software focus and became the public face of the modern firm - and, along the way, the first Puerto Rican-born billionaire, a ranked junior tennis player turned dealmaker. Around them sits a bench of operating partners who move into portfolio companies to work on margins, go-to-market and further acquisitions. The firm employs several hundred people across six offices: Chicago, Dallas, London, Miami, New York and San Francisco.
07 / Where it fitsThe other side of the cap table
Most technology coverage points at the companies building software. Thoma Bravo lives on the other side of that table - among the owners. Its closest peers are the other tech-focused buyout houses: Vista Equity Partners, Silver Lake, Francisco Partners, Permira and Hg, along with the technology arms of giants like KKR and Blackstone. What distinguishes Thoma Bravo within that group is the sheer consistency of the method: a preference for market leaders, an operations-first mindset, and a willingness to keep running the same play at ever-larger scale.
For the companies it buys, the pitch is capital plus a proven operating system. For the institutions that back its funds, it is access to software returns without having to pick individual winners. And for everyone else, it is a reminder that a lot of the technology the economy runs on is owned quietly, one methodical acquisition at a time.
