Corporate News

At sonntag corporate finance we know:

To build your own business, you need more than just a clever idea.
You need passion, competence and enthusiasm.
We are on hand with the same drive when it comes to managing company successions and thus protecting lifelong enterprises.

As one of the largest providers of Mergers & Acquisitions (M&A) in the German SME sector, we advise our clients exclusively on the sale of companies – and have been doing so for more than 15 years. From anonymous market research to the final signing of the contract, Sonntag stands for professional service and the highest level of discretion.

For our innovative approach, we were already awarded the “Best of Consulting Mittelstand” award in the field of M&A by WirtschaftsWoche in 2018. And this year we can also look forward to 2 further awards as “TOP Consultant” and “TOP 100”.
