Quick access to fresh equity

Equity capital is the foundation of every company. Around 150,000 German SMEs currently have a need for capital. Unlike debt capital, however, this cannot be found at a bank or savings bank. At the same time, a good equity ratio promotes the company's positive credit rating, which is necessary when accessing short-term debt capital.

Your fast access to fresh equity is the Beteiligungsbörse! As the first platform in the German-speaking region, we offer you the complete process for efficient capital procurement from EUR 1 million - from the initial meeting to the closing. We support you throughout with innovative technology and personal expertise. All this at transparent and fair conditions.

  1. Structuring fee EUR 5,000
  2. Transaction fee EUR 5,000 plus variable base fee for the external transaction advisor
  3. Performance-based closing fee of 6% of the transaction volume. All fees from 1 and 2 are creditable against this.

As an entrepreneur, do you need additional equity to drive the growth of your business? Do you, as a managing director, see with concern how the equity ratio has decreased as a result of the recent crises? Or, as a shareholder, would you like to sell part of your stake?

Then register here for a no-obligation consultation with one of our experts.
