about our services

"Dr. Stahl advised us significantly on the development and legal implementation of our business model as a financial services institute as well as in the context of the approval procedure of the financial supervisory authority, as well as on the entry in the legal services register of the Regensburg District Court as a debt collection service provider. "

“Together with KEYTERSBERG we developed a strategy to protect our trademarks and copyrights. Thanks to the expert advice of Dr. Stahl we are now able to defend ourselves quickly and successfully against plagiarism and free riders. A strong foundation for our brand and our company. "

“KEYTERSBERG played a key role in developing our business model. With the data protection system designed by KEYTERSBERG, we can offer our customers the highest quality without drowning in bureaucracy. In addition, Dr. Stahl contributed significantly to the success of the previous financing rounds. "

“For us as a financial company, the legal protection of the business model is vital. KEYTERSBERG has set the decisive course for us and designed an optimal set-up in terms of regulatory and taxation. "

“As a provider of services in the digital sector, we need legally secure and understandable contracts. KEYTERSBERG drafted the sample contracts and terms and conditions for us and trained us in dealing with legal documents in such a way that misunderstandings for the customer cannot arise in the first place. That saves us and our customers time, trouble and money. "

“Due to our B2B business model, we had to deal with large contracts from the start that our customers in the automotive sector presented to us. KEYTERSBERG supported us with extensive training on the most important content of contract law and with contract formulations in individual cases. "
