This feels kinda sketchy tbh... Fresh HN account with just this posted, fairly high rate of upvotes for what seems to be a mundane and vague product, link to a mailchimp page (usually used for email marketing) rather than an actual site, I couldn't find this link shared anywhere else, and as you say, no mention of who made it.

I signed up with a disposable email and didn't get anything. I'm getting slight vibes of someone trying to harvest HN user emails because this product seems so generic lol. Phrases like "Finding trends", "Predict time series data", "Something Awesome is Coming Soon", and "No limits to what you can do" seem... not like phrases an actual AI startup would use.
