I'm really happy for Josh, I loved the blog posts. Always so honest and straight forward. Sadly, many SaaS companies hit a brick wall after initial investments and the first growth streak. Especially, analytics companies.
I've worked with a mobile analytics company in the past and it was pretty much the same story. Only, they weren't as transparent and couldn't walk away with a profitable exit.
So this really looks like the best way he could exit without burning himself out.
