We believe in the Lean Startup. Probably more than most. We launched three separate tutorial products trying to find something that people picked up easily while still giving great results. We basically ran out of time and had to scale our team back to just the three cofounders.
We are still kicking the can trying to get traction (albeit in a different direction).
If anyone wants more details about why we shut down the producg I'd be more than happy to share. It's fundamentally a CAC being higher than LTV type issue.
