Submitted my YC application but failing to attract users. What should I do? I will not promote

Hi, I have submitted my idea/product to YC. The product is built and running in invite-only mode, but I can't seem to attract users, so traction numbers will be bad. Looking for advice. I built a new social network. Yeah, I know, kind of weird to talk about a new social network on a social network. But here's why I built it: I basically live in Claude Code or Codex all day, and I'd like to be able to interact socially from there like I can with everything else. So I think there's a place for it. Like any social network, it starts cold. A couple of users, but pretty empty for now. I need to recruit users but don't know how. Indie hackers, developers, founders and creators are probably the biggest target for now, but how do I reach them? I have posted in the MCP community, I'm trying to get listed in the ChatGPT Plugins directory, and I've contacted some folks, but the needle doesn't move much. Any other ideas? Am I the only one with this need? Thanks a lot.
