Horn Group is promoting the "Launch" initiative developed in conjunction with the Alliance for Downtown NY to accelerate the transformation of the lower Manhattan financial district into a high-tech hub.

launchSabrina Horn told O'Dwyer's that her firm sent 300 invitations to the Sept. 17 event held in the ornate lobby of the Woolworth Building, an architectural gem across the street from City Hall Park and Brooklyn Bridge that ruled as the world’s tallest building from 1913 to 1930.

The audience of young techies, entrepreneurs and venture capitalists packed the hall. One speaker in referring to the year 1995, remarked "most of you were in grade school then."

Horn believes the area is at a "tipping point" as more than 600 companies tech/media/design companies already call it home.

That roster includes Sapient, Droga5, Cake, Booker, Refinery29, Inc., Rock Shrimp Productions, AppSense and Fast Company.

Horn's firm is responsible for the firm's integrated communications including messaging, website development and social media.

Launch will play up the area’s marketing points including 1) larger, flexible, affordable and modern office space; 2) the nation’s most state-of-art advanced fiber-optic network; 3) outstanding subway, bus, ferry and Path to New Jersey transportation links, which will be enhanced next year with the opening of the Fulton Center and World Trade Center hubs; 4) plenty of restaurants/bars; 5) abundant park, plaza and outdoor areas;  6) tech lectures and networking events held at The Hive, the high-tech incubator at 55 Broad St., former home of the vanquished Drexel Burnham Lambert investment firm.

Horn, whose shop is based in San Francisco, moved to New York following the WTC terror attack to help the city rebuild.

She opened a Horn Group outpost in NYC at 55 Broad with the long-term plan of duplicating SF's high-tech infrastructure here.

At the Launch party, she told O'Dwyer's, "This is what I've been trying to do."
