San Francisco -- Pathbrite, the San Francisco-based developer of digital portfolios designed to help students showcase their achievements, said on Thursday it has raised $2.5 million in its first round of funding, led by Rethink Education. ACT also contributed to the round, which the company will use to continue product development and user acquisition. Pathbrite now has raised $4 million since its inception. Pathbrite allows students to aggregate all of their digital artifacts -- such as certified transcripts, report cards and earned credentials -- into a single place, where they are then able to curate and publish portfolios for either targeted or broad audiences. "Pathbrite enables individuals to truly differentiate themselves and to stand out from the crowd,” said Heather Hiles, the company's founder and CEO.The company's basic version is free to use, with plans to unveil other premium features over time.
