Global Equity Partners Beteiligungs-Management GmbH
 Global Equity Partners Beteiligungs-Management GmbH Investment ManagersFinance GEP is an active, long-term manager which provides seed- and start-up financing, invests in expanding industries and structures management buy-outs and company takeovers. The firm seeks to invest by partnering with investee firm management and act as lead investors in diverse lines of business, targeting majority and minority shareholding positions. GEP aims to invest in companies with clear and comprehensible business projects, significant experience in their industry, business targets that correspond to theirs, already acting in worldwide expanding markets or about to enter those markets and which offer products with a competitive edge or services which are technologically different from other companies. The firm always defines the form of divestment after the required growth period in advance, typically considering an IPO to be the best alternative, but also exploring the sale of their equity stake to a strategic partner or even to other shareholders. GEP reviews realization options with the investee company and selects the best option. The final decision is taken as late as possible, so as to reduce market and default risk. | Chief Executive Officer | 1997-12-31 |
