While at the NDC London conference, Carl and Richard talk to Liam Westley about building your own software business. It starts with the idea that the most destructive thing to your software business is support calls - or more broadly, the accumulated cost of your past business. The conversation digs into the power of being a business of one, rather than having employees, and thinking beyond just your development work, digging into all the other aspects of business: marketing, sales, accounting, and so on. As Liam says, starting a software business is easy, staying in business is hard!
