I'm in the process of launching my self-funded search in Germany. To prepare initial talks with investors, I want to better understand how a typical equity structure for self-funded deals looks like.

Of course, the unglamorous life of restricting one's diet to canned ravioli and instant ramen is rewarded with higher searcher equity. However, I found only very limited information on the actual deal structure of self-funded acquisitions with outside investors (e.g. with regards to searcher equity shares, vesting, hurdles, preferred equity etc.).
I'd be incredibly grateful for any advice on relevant materials and/or personal experience.

Thank you very much for your help!
