It's a myth that large companies have a lot of repitition tasks. They know how to automate. No need to tell them what they already do.

As my postings are focussed on the German market, I rarely see real Lean Startups that. It's still very common to build one thing big and to hope that it succeeds. So actually you don't start from scratch more than 1 time except some low profile developers messed it up.
