The key (based on my exp with these 3) is the composition of the team.

At least 1 person on the team needs to have domain experience and if solo, that solo founder needs to have domain experience and good connections or the wherewithal to get the first handful of paying customers via cold calling, cold emails. The main challenge remains sales, marketing, and branding. There are free CRMs and anyone can build a CRM. Why do some CRMs succeed while others fail? Branding, marketing, awareness.

So I don't see it as "there will just be 10x more competitors" because I've built enough stuff that I failed to sell and used enough shitty software to know that the software itself is rarely the reason why people buy X over Y. It's because they didn't even know Y existed.
