Question
Eric Ries intimated in "Lean Startup" that nobody would steal our ideas, but I have concerns with an external agency or developers having possession of source code that would be the core of our business. Is this an unfounded fear?
When funding permits, I would like to explore having an in-house development team, but quality agencies and developers seem to be available to hire in abundance. If my startup is bringing in revenue and profiting, is it unusual to continue a working relationship by outsourcing development to a third party?
I'm thinking in the most economical sense, that this is sensible, however there are certainly other concerns to consider.
Answer
Christopher provides an excellent answer. The one thing I might add is: be wary of dev shop claims to understand what an MVP is. Despite the success of Lean Startup, I'd argue most dev shops still don't know how to build and iterate MVPs. It sort of runs counter to their business model.
