Ontario Teachers’ Pension Plan Board has purchased ownership interest in Mitratech, from private equity firm TA Associates, as part of Mitratech’s sale to at an enterprise value of $1.55 billion. Mitratech’s portfolio of end-to-end software services are used by corporate legal departments.

“Since beginning our partnership with Mitratech in 2015, the business has successfully executed against its growth strategy through organic initiatives and strategic acquisitions, expanding its software offerings and global reach,” said Hythem El-Nazer, managing director at TA. “We believe that Mitratech is well-positioned for continued acceleration in growth going forward.”

“The acceleration in growth, operational excellence and results at Mitratech have been impressive,” said Mark Friedman, former chairman of Mitratech and ST6 managing director. “The company has a commanding market leadership position and tremendous momentum, and it will be exciting to watch Mitratech’s future success.”

“TA and ST6 have been invaluable partners over the last six years,” said Mike Williams, CEO of Mitratech. “TA has been pivotal in driving our acquisitions and ST6 has been instrumental in scaling the company and accelerating our overall progress. It’s been great to work with Mark and Hythem again, and I appreciate their contributions to Mitratech’s success.”
