More informationOur expertise in detail
There is often no clear participation architecture, bad contracts, incomplete data rooms. It is up to you as an investor to “clean up” before and with participation and to create structures that enable long-term growth. With our advice, you get:

Screening of the target, before due diligence to set the DD standard and strategic deal architecture.
DD specifically tailored for startup participation, which in some places resembles a superficial Red Flag DD and in critical areas of a deep vendor DD, in an overview report.
Easy-to-process list of recommended actions to prepare and implement the transaction and resolve any findings.
We will set up a standard contract setup for you that we can use over and over again and can adapt accordingly to each matter.
Overview for monitoring individual tasks, deadlines and trigger events.
Over a period of around 6 months, we support the company and its management and provide knowledge, templates, know-how, quality and structure in order to achieve the greatest possible optimization of participation for all shareholders.
Individual legal advice within the framework of a structured mandate architecture. Exclusively for institutional investors, family offices and business angels. Every transaction involves risks. We help you to manage them systematically.
