Lynne here! I wrote this article and hope I didn't make it sound like I did it all alone. I had a lot of help, guidance, mentorship, and support along the way.
While I don't have a cofounder or someone who is working alongside me on Key Values, I absolutely would not have gotten here without help. Even without a cofounder, people can (and should!) find help, guidance, mentorship, and support from forums like Indie Hackers and dev.to.
