Positioning yourself as specifically designed for solo and small team project management to me is an underserved market. When I looked at your landing page, I scrolled down quickly thinking "cool another PM tool... just what the world needs". Then when I saw the line 3/4 of the way down that said "Specifically designed for solos, small teams and businesses" that caused me to perk up and go back to the top and look at the page from a different perspective that I was much more interested in.
I see now looking at it again that you mention "personal productivity" which I now understand is your way of saying small and solos. But I just interpreted it as a PM tool that made you productive amongst your team. So it didn't really resonate to me.
Anyway, the product is actually interesting. I'm going to check it out. I've been wanting a PM tool for solos. There are a couple out there, but they all suck. The best solution up to this point for solo project management that I have found is just using a generic solution like Notion or Trello and adapting it to my needs. So this is worth a shot IMHO.
