Edmodo, a free K-12 social learning network based in San Mateo, California, has closed a $25 million Series C funding round led by new investor New Enterprise Associates (NEA). Existing investors Greylock Partners, Benchmark Capital, Union Square Ventures, and Learn Capital, also participated in the funding round.
