This document outlines 7 lessons learned from co-owning a design business for 7 years. The lessons are: prioritize client services and products; trust your instincts on projects; manage finances carefully; use the appropriate tools for each job; develop talent within the company; find a business partner with complementary skills; and implement ideas to generate value rather than just conceiving them.
