Oakley Capital Investments, a Bermuda private equity firm, has acquired a majority stake in 7NXT, the Berlin-based parent company of Gymondo and two other businesses, with an investment of €42.6 million and a plan to expand their operations further in Germany and internationally. The sellers are the company’s founder and chief executive, Markan Karajica, and Crosslantic Capital. Karajica will continue to serve as CEO, retaining a minority interest. Founded in 2013 and led by Simon Grünenwald, Gymondo is a health and fitness app that offers short workout videos and customized meal plans, targeting mainly women. It has registered more than two million accounts since its start, and the number of its followers on Instagram has reached around 50,000. A few weeks ago, Gymondo was rated the best online fitness studio by Stiftung Warentest, the German product testing agency for consumers. The two other assets of 7NXT are Brand Solutions and Shape Republic, a direct-to-consumer brand of nutritional supplements.
