The round was led by Techstars Ventures, as it builds an index of health and human services programs available in cities across the U.S.

The company's website lets users search for any type of social service -- from legal aid to day care to healthcare education -- by topic and by zip code. You can find the location, hours, and reviews of the services through the site, which also has tools to help users reach the social services provider.

The value of the service, the business model, and the customer list -- which includes hospitals, foundations, and health insurance companies -- is what attracted Techstars Ventures to the company, according to Jason Seats, a partner at Techstars Ventures and a board member of Aunt Bertha. The basic service is free to the public and Aunt Bertha provides an enterprise version for companies, such as employers of case managers or social workers, the company says. The company has more than 45 enterprise customers, a spokeswoman says.

Aunt Bertha has been indexing health and human service programs, including those provided by charities and governments, since it was founded in 2010 by CEO Erine Gray. The Social Entrepreneur Fund, which is based in New York, is also an investor. The company raised almost $1 million in 2013, according to a regulatory filing.

Techstars Ventures is the venture capital arm of Techstars, the Boulder, CO-based accelerator with more than two dozen programs around the world. Seats launched the Austin Techstars program before joining Techstars Ventures.
