Y Combinator alum Strikingly launched earlier this year with the mission of enabling people to build Web sites in just a few minutes. With the launch of its new one-click site builder, the startup has now reduced that time to seconds.

The one-click site builder, which Strikingly bills as “the world’s fastest Web site builder,” automatically fills in a mobile-optimized site with information from your Facebook account, including your profile picture, work experience, hometown, current city and contact information. You then have the option of customizing your site with new content, photos or additional slides.
