Sam Rosen, former New Yorker, just presented his start-up Speakergram, a platform for organizing and booking speaking engagements, at the 500 Startups Demo Day in Mountain View. He started the hunt for funding a week ago and already has commitments from New York investors including Alexis Ohanian (Reddit), David Tisch (TechStars), Jason Finger (Seamless Web) and Mike Yavonditte (Hashable) totaling $500,000 $250,000–half of what he’s looking for.

The audience in the chatroom also approved of Speakergram. “This will be bought by LinkedIn,” one watcher commented.

500 Startups companies will also be demo’ing at General Assembly later this month.

CORRECTION: This post originally misstated the amount Mr. Rosen is raising; he is seeking $500,000 total, not $1 million.
