I am a co-organizer of Byteconf Flutter , and one thing that I have noticed over the last few months is that there's a dearth of tools for managing conferences. Having seen the success of Codeland, I think there's an opportunity here. Some things that I think are noticeably missing:

Tools to organize conference schedules & talks

Currently, we use a combination of tools (papercall, notion, etc.) to manage the pre-conference lifecycle. None of these tools feed into each other.

Tools to announce conferences (via blog post)

Similar to the former issue, creating a blog post to announce the conference is a very manual process.

Tools to manage conference speaker info

Being able to pull speaker info directly from a place like Hashnode would be extremely useful. I'm imagining a system where users could submit conference talks directly and their profiles would be automagically pulled in if their talk is accepted.
