Similar here. I'm not a solopreneur, but I keep writing down ideas — a lot of them. I have a folder that says “Ideas,” and I tinker-write about the problem-solution, etc., when my mind wonders or the weekends after the digital chores.
I also tend to get lots of gotchas while walking, I use the Voice Memo in the phone to just talk to and I write it down when I'm home and in front of the computer.
I also have lots of pen-paper notebooks that I write like crazy all the time. I'm beginning to take a lot care about my "CommonPlace Notebooks" now. Earlier, I use notebooks as a temporary idea-holding medium.
