Boston-based Flybridge Capital Partners has officially opened the doors to its New York office. David Aronoff, one of the firm’s five partners, moved to New York earlier this year. He’ll lead the office’s investments alongside Principal Matt Witheiler, who recently moved to New York, and a new associate hire.

Caitlin Strandberg last month joined Flybridge from Learnvest, an online financial advisory startup based in New York. She previously worked in business development at Behance, another New York startup.

Flybridge Capital Partners focuses on seed and Series A stage investments, having backed NYC startups like 10Gen, 33Across and Tracx. The company is currently investing from its third fund, a $280 million 2008 vintage.

The firm’s growing presence in New York reflects the increasing attention its partners have given the city’s startups. Aronoff says that this year, his typical deal flow split of half Boston companies and half New York companies has tilted in favor of New York this year by a margin of three to one.

The firm’s investments are still evenly divided between the two cities with 20 of its deals coming from outside the East coast, but that may also change with a full team in Soho. Partners at Flybridge have served as mentors to New York startups through New York TechStars, General Assembly and First Growth Venture Network.

Flybridge invests in “Enterprise 2.0″ companies as well as consumer infrastructure companies, Aronoff says. Startups working on next-generation TV solutions, innovation in education, adtech and fintech are also big themes for the firm.
