A seed fund grows in Brooklyn.

High-profile New York investor and entrepreneur Charlie O’Donnell has launched Brooklyn Bridge Ventures — believed to be the first outer-borough focused tech fund.

O’Donnell announced his new venture yesterday, with more than $10 million for seed-stage financing of start-ups.

Brooklyn is growing in prominence as a micro-hub within the city’s tech boom, and has seen big growth from companies such as online-do-it-yourself merchant site Etsy.
