Founded in 2004, StoneTurn has advised more than 95% of the AmLaw 100 and more than half of the Fortune 100, as well as federal, state, and international government agencies. The firm’s experience on high-profile investigations, litigation, and disputes worldwide, along with work on more than 30 monitorships, demonstrates an exceptional ability to deliver credible, independent insight where rigour and judgment are critical.
MML completed a minority investment into StoneTurn in late 2019, facilitating the firm’s transition from partnership to corporate – streamlining strategic decision-making and aligning partners to drive capital value in the group. Since MML’s investment, StoneTurn has transformed its business by investing to build out several highly complementary new practice areas, including adding ~10 lateral partner hires and expanding into two new continents.
The transaction with Trivest-backed Province, which signed in Dec-25, creates a multi-disciplinary advisory platform with expanded capabilities and global reach, whilst critically allowing StoneTurn to maintain a practitioner-led, client-first operating model largely free of institutional conflicts. The combined firm will boast 300+ professionals operating across 19 offices on five continents, and on-the-ground experience in over 100 countries. With expanded capabilities and global reach, StoneTurn is exceptionally well positioned to deliver greater speed, coordination, and insight into matters where financial, legal, and operational risks intersect.
Ian Wallis, CEO at MML, commented:
“We are extremely grateful to Brad, Christopher, Simon and the whole partner group at StoneTurn for their immense efforts during our partnership. They have built a firm full of truly exceptional talent whilst successfully retaining a unique culture, as has always been evident in our working relationship. We are delighted to leave StoneTurn well-positioned for continued successes.”
Brad Wilson, Managing Partner at StoneTurn, added:
“Our experience with MML was exactly as we hoped. The MML team brought thoughtful, independent advice and support with critical strategic priorities, and equally allowed us to focus on managing our day-to-day business operations. They have been a pleasure to work with and are true partnership investors.”
MML and StoneTurn were advised by Clearsight Advisors, Kirkland & Ellis and CohnReznick. The MML team included Ian Wallis, Sean Quinn, Will Stewart & Chandler Kirby.
