Private equity in action - Case Study

Lautsprecher Teufel

Back to results
Country Germany
Region Berlin
Investor The Riverside Company

When the founder of ‘Lautsprecher Teufel’, the German loudspeaker designer and manufacturer, decided it was time to step away from his day-to-day role after more than 25 years, he identified private equity firm Riverside Europe as the ideal partner to take the company forward.

Riverside quickly identified a new CEO and built the board – all industry experts who could share their experiences and networks to support the growth of the business. During the four-year investment period, Teufel grew at three times the rate of the overall German audio market, and became one of the most successful investments in Riverside’s history. Riverside sold the business in 2010.
