MightyMeeting, a mobile meeting app for iPhone and Android platform handsets as well as PCs, today announced it has secured a seed round of funding for $300,000. The seed round comes just 21 days after launching at VentureBeat’s DEMO Spring 2010 event, a relatively short timeframe in which to secure funding by industry standards.

Founder Dmitri Tcherevik (pictured) told VentureBeat the funding will be used to build out the infrastructure and launch a premium service for the company’s business customers. Additional plans include expanding the list of mobile platforms the service supports and partnering with telcos and device manufacturers.

MightMeeting is helping mobile users to organize and search through PowerPoint presentations right on their mobile devices. A user can create an online meeting request, for example, invite others and then walk through a PowerPoint presentation. Each time a change is made to a slide, it changes for the others as well.

The New York City based company met many of its angel investors through Venture Hack’s AngelList, an up-to-date listing of active angel investors around the world. Participants in the seed round included George Zachary (Charles River Ventures), Bill Lee, Shervin Pishevar, Andrea Zurek (XG Ventures), David Lee (XG Ventures), Greg Lee (XG Ventures), Pietro Dova (XG Ventures) and Cooley LLP.
