How to announce a funding round covers this: the round is the news and the post has to turn it into customers and hires. For the next one, read launching a product on X from a small account: an account with 1K followers has to earn every view from outside its own following.
Giving people something to reply to is the guide for it: the conversation is what carried this one. Every launch we track in Healthtech AI is on that vertical's directory page.
