Show HN: Semi – AI helps you reply emails in a few taps

While we are working on it, we launched this site to gather those people who have the same passion about AI stuff as we do. We want to get connected and to see how people think about it, and make Semi to be the best virtual assistant of the future together.

This is real and it's coming.

This is a better strategy, see if theres a big enough market. They're also building the list so that their launch will be good and they don't have to spam it everywhere else, they just alert the people who already expressed interest.

There's nothing wrong with finding demand first, smart startups do this all the time.
