This is so funny. I did exactly the same thing. I mean, exactly!

I wrote a podcast transcription service using IBM's Watson API. And as a result, having realised it was getting a very crowded space and I had neither the energy nor marketing skills/money to launch it alone, I contacted the CEO of a leading transcription company and landed a gig to build out their mobile product. At least my app will now get a high profile launch, and not vanish without trace. Plus, I get paid.
