Winterberg-backed Schweizer Treuhand Holding acquires excent AG

excent, a Swiss fiduciary firm founded in 2006 with about 22 employees, has offices in Wollerau, Zurich and Zug.

The holding company is managed by Winterberg Advisory GmbH, and the parties marked the closing at an event in Steinhausen, Switzerland.

excent was founded in 2006 by Maximilian A. Friedery, now Chairman of the Board of Directors, and Bruno Eugster, a board member and CEO. With offices in Wollerau, Zurich and Zug, the firm has about 22 employees serving corporate and private clients in payroll, accounting, tax, virtual office services and corporate advisory.

Friedery said the deal gives excent a path to long-term stability and growth within a group of independent fiduciary firms. Eugster said the firm will keep its name and locations, with clients served by their existing contacts. Ralph Nowak, Chairman of Schweizer Treuhand Holding AG, said the acquisition extends the group's footprint across Central Switzerland and Zurich, following the Smart Group deal weeks earlier.
