LONDON—Instinctif Partners has acquired Wriglesworth, a London consultancy that focuses on corporate affairs.

The acquisition of the £2m firm takes Instinctif's corporate and capital markets practice to around £12m in revenue, employing 90 people.

Wriglesworth's 25 staffers will move to Instinctif's London office. Instinctif capital markets and corporate CEO Tim Fallon added that the the Wriglesworth brand will also cease to exist "within the next few months."

Wriglesworth founders John Wriglesworth and Laura O’Connell will join Instinctif's capital markets and corporate affairs team as managing partners, under the leadership of Fallon.

Founded in 1998, Wriglesworth is best known for its work in the financial services, property, business services,rRecruitment and HR sectors.

"The strong variety of complementary skills in both organisations means that this is a very natural evolutionary union," said John Wriglesworth. "I feel like we are now turning from a strong maverick caterpillar into a sustainable butterfly."

Since being acquired by private equity firm Vitruvian Partners in 2011, Instinctif has steadily accelerated investment in its global expansion, acquiring firms and launching new operations in India, Europe, Dubai, Shanghai, Beijing and Hong Kong in recent years.

"Along with our own organic growth and success in recent years, this acquisition is another step forward in fulfilling our ambition to build one of the world’s most successful and respected international business communications consultancies," said Instinctif CEO Richard Nichols.
