  • I've found Diederik/Keystone to be an invaluable part of our story, as a startup founder it's important to surround yourself with the best people that complement your weaknesses and can offer solutions. Diederik has a refreshing approach to startups and continues to add value across HR, legal and general business practices as legal counsel and non-exec director to KLEEK. I can not recommend Diederik enough and look forward to working with him for years to come.
