I'm starting a SaaS business. What is a fair participation percentage for me? There are three guys involved in this and so far this is what we bring to the table: - Them: A medium size customer waiting for the service to be ready. A sure sell with influence in the market to push it to new customers. (this first customer will get a partner price in exchange of spreading a good word about the business) - Me: Everything else, all of it. Product design, software development, user testing, infrastructure set up, maintenance etc.
