https://indiehackers.com has local communities around the world and online forums for discussing technical and non-technical startup processes

There's even a group: https://www.indiehackers.com/group/looking-to-partner-up

In my experience Indie Hackers has an unusually high concentration of people who get things done, the kind of people with grit who you might want to partner with.
