Self-defense technology start-up Roar for Good L.L.C. of Philadelphia is finishing the year with a roar.

The company concluded a crowdfunding campaign on Indiegogo over the weekend with $267,320 raised, exceeding its goal by 668 percent.

Manufacturing of its Athena, a wearable help-summoning and alarm device the size of a half-dollar, is expected to begin this month, with order fulfillment expected in April.

The Indiegogo campaign yielded orders for nearly 4,000 devices from 47 countries, said Yasmine Mustafa, Roar cofounder and CEO. Nearly 240 Athenas will be donated to Women Against Abuse Inc. in Philadelphia, she said.

Roar also announced Tuesday it is the Philadelphia region winner of the SBA InnovateHer Challenge Competition, sponsored by the Alliance of Women Entrepreneurs and the U.S. Small Business Administration. That qualifies it to compete in March against seven other finalists for $70,000 at a national pitch contest in Washington.
