Plancast, a startup which lets users share their plans, has raised $800,000 from SoftTechVC, True Ventures, Founders Fund Angel, Zelkova Ventures, as well as a number of angel investors. On Plancast, users post what they plan on doing later; users can track each others’ accounts and also indicate publicly that they too plan on doing the same thing.

Co-founder Mark Hendrickson tells us that the site—which launched in November—boasts a membership in “the thousands.” Ultimately, he says Plancast may make money via targeted ads (i.e. you say you’re heading to New York for the week-end, so maybe an advertiser could show you a coupon for a hotel in the city) and also via premium accounts for businesses. Hendrickson worked as a web developer and reporter at TechCrunch before leaving to start the company last spring.
