None. We sign NDA's for specific clients. Other than that, we don't have a non-compete or similar clause prohibiting side work. In fact, it's encouraged. We talk about our side projects openly. Also, if you want to have some company backing on your project, you can get paid 50% of your effective hourly rate for every hour you work on your side project if you agree to split potential profits with the company. Kind of an in-house funding.
