Ince UK managing partner leaves firm less than a year into role

Mark Tantam has left Ince to work in his own non-legal advisory firm


Ince’s UK managing partner Mark Tantam has departed the listed UK firm after ten months in the role.  

He left Ince last month to pursue interests outside the legal services sector, the firm said.   

Tantam joined Ince as global head of consulting in October 2019 from Deloitte, where he spent more than two decades as a partner in the Big Four firm’s forensic practice. Prior to his departure from Deloitte, Tantam aided in the search for a permanent head of the audit firm’s UK legal business as interim leader before becoming vice chairman and partner of Deloitte Legal after the firm tapped Allen & Overy partner Michael Castle to fill the top role.  

Tantam focused on building Ince’s non-legal services division as its global head of consulting before taking on the additional role of UK managing partner last autumn. In the dual leadership roles, he oversaw the firm’s legal business across its regional offices in London, Cardiff and Wandsworth.  

His appointment as regional managing partner coincided with a leadership shakeup that saw former Hill Dickinson shipping head Julian Clark become global senior partner and former Orrick Herrington & Sutcliffe partner Alex Janes become international managing partner for the firm’s operations in the Europe, Middle East and Africa region.  

Following his departure, Tantam will continue his work as director of non-legal advisory business Regvisory, which he co-founded earlier this month, according to his LinkedIn profile. The startup focuses on advising regulatory technology companies and fintechs funds on where to invest.  

Ince’s board said Tantam was a “valued colleague” during his time at the firm, and expressed its gratitude for his contributions to the business throughout the pandemic and the UK’s national lockdowns.  

The firm has had a busy few years since professional services firm Gordon Dadds and shipping and litigation heavyweight Ince & Co merged to become Ince Gordon Dadds and list on the Alternative Investment Market in 2017, later changing its name to The Ince Group, or simply Ince.  

It was the second UK law firm to list on the stock exchange after Gateley made legal history by going public in 2015.  

In its first full-year financial results as The Ince Group, the firm narrowly missed its revenue target for the 2019/20 financial year, with revenue clocking in just shy of its £100m target at £98.5m. At the time, group chief executive Adrian Biles said the results were pleasing given the disruptions caused by Covid-19 and praised its “year of great progress”.
