Who owns PowerSchool? Ownership structure explained (2026)

PowerSchool sits inside tens of thousands of American classrooms, yet most parents who log in to check a grade have no idea who controls it. The company runs the student information systems, enrollment tools, gradebooks, and analytics that more than 60 million students and their schools rely on across North America. Ownership of that infrastructure has changed hands repeatedly over almost three decades.

The short answer today is Bain Capital. In October 2024, the private equity firm completed a roughly $5.6 billion buyout that pulled PowerSchool off the public market after just three years as a listed company. The two firms that owned PowerSchool before the IPO, Vista Equity Partners and Onex, both stayed in as minority holders.

That ownership question took on new weight two months after the buyout closed. In December 2024, PowerSchool disclosed a data breach that exposed the personal information of tens of millions of students and teachers, one of the largest breaches of children's data on record. Understanding who owns the company, and who answers for its security, starts with how PowerSchool got here.

PowerSchool traces to 1997, when Greg Porter installed the first version of his web-based student information system in Utah's South Summit School District. The browser-based design set it apart from the desktop software schools used at the time, and the product spread quickly.

The company is headquartered in Folsom, California. Its core business is cloud software for kindergarten-through-12th-grade education: student information systems, enrollment and registration, attendance and grading, special education case management, human capital management for school staff, and analytics that tie the pieces together. Schools pay recurring subscription fees, which makes the business a vertical software-as-a-service company serving public and private districts, the kind of sticky model that runs through most SaaS revenue and retention statistics.

The last full year PowerSchool reported as a public company, fiscal 2023, brought in $697.7 million in revenue, up 11 percent year over year, with annual recurring revenue of $701.5 million. The most recent valuation benchmark is the $5.6 billion enterprise value Bain Capital paid to take the company private in October 2024. Because PowerSchool is now private, it does not report a public market capitalization, and it discloses far less financial detail than it did on the NYSE.

PowerSchool is privately held. It traded on the New York Stock Exchange under the ticker PWSC from July 2021 until October 1, 2024, when Bain Capital completed its acquisition and delisted the stock. Control now rests with Bain Capital as majority owner, alongside minority stakes held by the two firms that owned PowerSchool before its IPO. This structure sits somewhere between the founder-led model and the widely held public float, closer to the take-private playbook that also defined Dell's return to private ownership before it relisted.

Greg Porter has not held an ownership stake in PowerSchool for many years. He sold the company to Apple in 2001 for about $62 million in stock, and the business changed hands several more times after that. The PowerSchool that exists today is a private-equity-assembled roll-up rather than a founder-controlled firm, and there is no public disclosure indicating Porter retains equity. Founder ownership, in the sense of a controlling or meaningful personal stake, does not apply to PowerSchool.

PowerSchool's history is a chain of acquisitions and one public offering rather than a series of venture rounds. The table below traces the transactions that set today's ownership, with values as reported at the time.

Bain Capital is the controlling owner. The Boston-based private equity firm agreed to buy PowerSchool in June 2024 and closed the deal on October 1, 2024, paying $22.80 per share in cash, a 37 percent premium to the unaffected share price of $16.64 on May 7, 2024. Bain now steers the company's board and strategy.

Vista Equity Partners bought PowerSchool from Pearson in 2015 for about $350 million and rebuilt it into a broad K-12 platform through acquisitions. Rather than exit entirely in the Bain deal, Vista retained a minority investment.

Onex, the Toronto-based private equity firm, acquired a 50 percent stake from Vista in 2018 for roughly $870 million, making the two firms equal partners ahead of the IPO. Onex also kept a minority position after the Bain buyout. Following the 2021 IPO, Vista and Onex together still controlled about 78 percent of shareholder voting power, which is why the take-private required their cooperation.

As a listed company, PowerSchool used a dual-class share structure common to private-equity-backed IPOs, with the sponsors holding voting control. That structure ended when Bain took the company private. There is no public float today, so ordinary investors cannot buy PowerSchool shares. The valuation and share-structure resets that mark this history are the kind of exercise a business valuation calculator is built for, translating enterprise value into per-share terms.

Antonio Pietri became chief executive officer on October 6, 2025. He previously ran Aspen Technology, an industrial software company he led from 2013 until its acquisition by Emerson in early 2025. His appointment signaled Bain Capital's intent to bring in an operator with a track record of scaling vertical software businesses.

Pietri succeeded Hardeep Gulati, who served as CEO for roughly a decade across the Vista, Onex, public, and Bain eras. Gulati moved into a senior advisory role to support the transition. His long tenure spanned the company's rise from a private-equity holding to a public company and back to private hands.

Control ultimately sits with Bain Capital, whose partners direct the board as the majority owner. Vista Equity Partners and Onex hold minority stakes and, based on their retained investments, likely keep board representation, though PowerSchool discloses less about its board now that it is private than it did in its NYSE proxy filings. The specific board roster is not fully public, so any detailed composition beyond Bain's control and the two minority sponsors should be treated as inferred rather than confirmed.

PowerSchool identified a breach of its student information system on December 28, 2024. An attacker had accessed PowerSource, the company's customer support portal, using the compromised credentials of a subcontractor. The portal did not require multi-factor authentication, so a username and password were enough to reach a maintenance tool with visibility across thousands of school districts. The intrusion traced back to September 2024.

The exposed data included names, contact information, dates of birth, Social Security numbers, and limited medical alert information for students and educators. Reporting placed the scope at roughly 62 million students and 9.5 million teachers, which would make it among the largest breaches of children's data in United States history. PowerSchool stated that fewer than 25 percent of its registered students had Social Security numbers exposed. The breach arrived less than three months after Bain Capital completed its buyout, putting the new owner's security posture under immediate scrutiny. For any acquirer, an inherited exposure of this scale is exactly the kind of item a risk register template is meant to surface before a deal closes.

The breach became an extortion case. The attacker demanded a ransom, reported at about $2.85 million in Bitcoin, and PowerSchool is believed to have paid at least part of it. The payment did not end the threat. Attackers later approached individual school districts directly, attempting to extort further payments using the same stolen data, which showed the limits of paying a ransom to make stolen records disappear.

Matthew Lane, a Massachusetts college student who was 19 at the time of the charges, pleaded guilty in 2025 to federal counts including aggravated identity theft, unauthorized access to protected computers, cyber extortion, and cyber extortion conspiracy tied to the PowerSchool hack. He was sentenced to four years in federal prison. The case did not resolve the civil exposure, and PowerSchool has faced litigation and regulatory attention from state officials over how the data was protected.

Ownership shapes accountability. As a public company, PowerSchool answered to thousands of shareholders and to the disclosure rules of the NYSE and the Securities and Exchange Commission. As a Bain Capital portfolio company, it answers primarily to one controlling owner and two minority sponsors. That concentration can speed decisions, but it also removes a layer of public reporting at a moment when families and regulators want more visibility into how student data is handled, not less.

For Bain Capital, PowerSchool is a bet on the durability of recurring education software revenue. K-12 districts rarely switch student information systems, which gives the business the kind of sticky, subscription-based cash flow that private equity prizes. It is a thesis that has pulled other classroom-software names off the public market too, a pattern visible in how Kahoot is owned after its own private equity buyout. The strategic logic also mirrors the case for entrenched enterprise platforms, from Oracle's founder-heavy ownership to widely held software incumbents. The risk is that the 2024 breach damaged trust with the exact customers whose renewals underpin that thesis.

For the private equity firms, the structure spreads both upside and exposure. Vista Equity Partners and Onex retained minority stakes, which lets them share in any future recovery in value while handing operational control and the primary reputational burden to Bain. Their decision to roll equity rather than exit fully signals confidence that the company can be repaired and eventually sold or relisted at a higher price.

For schools, students, and families, the practical stakes are trust and continuity. The people whose data PowerSchool holds have no say in who owns it, yet ownership determines how much the company invests in security, how transparent it chooses to be, and how it balances customer protection against the returns its investors expect. In a business built on the data of children, those trade-offs are the whole story.

Antonio Pietri has been CEO since October 6, 2025. He previously led Aspen Technology and took over from Hardeep Gulati, who ran PowerSchool for roughly a decade and moved into a senior advisory role.

No. PowerSchool traded on the New York Stock Exchange under the ticker PWSC from July 2021 until Bain Capital took it private on October 1, 2024. It has no publicly traded shares today.

Greg Porter founded PowerSchool and installed its first web-based student information system in 1997 in a Utah school district. He sold the company to Apple in 2001 and no longer holds an ownership stake.

Bain Capital is the majority owner and controls the company. Vista Equity Partners and Onex, which together owned PowerSchool before its IPO, each retained a minority stake after the 2024 take-private.

The most recent benchmark is the roughly $5.6 billion enterprise value Bain Capital paid to take the company private in October 2024, at $22.80 per share. Because PowerSchool is now private, it has no public market capitalization, and its current value is not disclosed.

PowerSchool passed from founder Greg Porter to Apple in 2001, to Pearson in 2006, to Vista Equity Partners in 2015, and to a Vista-Onex partnership in 2018. It went public in 2021, then returned to private ownership under Bain Capital in 2024, with Vista and Onex staying on as minority holders.
