Looking for a way to create "early-access" one-page no-code website

Hello All: Greetings. Is there a service out there that I can use to create a one-page no-code website? My goal is to capture site visitors info (email/phone# etc) and be able to know basic analytics (visits etc). This page is required to be live for next 2 months. I vaguely recall a startup focusing on similar idea but not able to find it anymore. Any ideas? Thanks.
