Looks like a neat tool!

I had 2 cofounders in my last company - I agree it's easier.

But so far, building in public has been a great way to replicate some of those benefits without one:

1. I have external motivation to produce results on a weekly basis.

2. I have to be able to justify all my decisions to everyone on the internet (anyone who cares at least...). I end up thinking things through more deeply.

3. I get continuous feedback from others - not nearly as good as a cofounder who's 100% in the business, but still helpful.
