In a neat piece of symmetry, Naik will be replaced as Channel 4 general counsel by Wiggin litigation consultant Amali de Silva.
Reviewed & Cleared founder David Burgess said that Naik is "at the very top of his game" and "completely understands our industry."
Naik said he is "looking forward to advising producers on both sides of the world on how to get the very best creative ideas to air."
Reviewed & Cleared, which was established in 2013, specializes in providing pre-publication and pre-broadcast advice to producers, broadcasters and not-for-profit organizations across all forms of media. The firm's clients include Cosmopolitan, Esquire and Wallpaper magazines.
Naik isn't the first senior media industry lawyer to join the media firm: Last September, Reviewed & Cleared hired Louise Hayman, who had spent 17 years as GC at British newspaper publisher The Independent and Evening Standard Group.
Wiggin invested an unspecified amount in the firm in 2016. The deal also provides Reviewed & Cleared with access to Wiggin's 70-plus fee-earners when it requires specialist expertise or additional resources.
In 2012, Wiggin became one of the first U.K. law firms to convert to a so-called "alternative business structure," which permits firms to appoint nonlawyer partners and accept external equity investment. (External investment has fueled massive revenue growth at some U.K. law firms, although such deals remain rare.)
Earlier this year, Wiggin established an executive production services company called Viewfinder and opened an office in Los Angeles to help source finance and distribution for movie producers and rights-holders. Wiggin has already acted as executive producer on a number of major movies, including "The History Boys" and 2015's "The Lady in the Van," starring multiple Oscar, Golden Globe and Emmy winner and "Downton Abbey" star Maggie Smith.
Wiggin also operates its own on-demand TV channel that has carriage contracts across Europe, and has developed a technology product that scours the internet for brand and copyright infringement on behalf of clients. Intelligent Content Protection, which was financed by luxury brand owner Compagnie Financière Richemont SA but is owned by the firm's equity partners, took on additional external financing in 2015 and now employs more than 40 system developers, analysts and salespeople.
