In a 900-square-foot Brooklyn Navy Yard studio earlier this week, the employees of spacesuit manufacturer Final Frontier Design were welding fabrics and planning designs.

Amid the activity, co-founder Ted Southern was rehearsing a two-minute pitch that could win his firm $50,000.

Move over, artisanal pickles and mayonnaise: There are new entrepreneurs in Brooklyn.

Final Frontier is one of 10 Brooklyn-based startups competing on Thursday in a pitch contest reminiscent of the television show “Shark Tank.” The contest is organized by the local development corporation Downtown Brooklyn Partnership, with prize money coming from Partnership co-chairs MaryAnne Gilmartin, president and chief executive of Forest City Ratner Cos., and Bre Pettis, founder of 3-D-printing company MakerBot.

The finalists, who were selected from 67 applicants, will give their super-short speeches, then field questions from judges for four minutes.
