Grokker has raised $5.5 million in Series A funding from Khosla Ventures, Josh Koppelman (First Round Capital), and angel investor Ron Conway. Grokker is a service that offers a network of online videos from experts. Some of the content on Grokker includes cooking, yoga, and fitness. Former eBay and Yahoo! executive Lorna Borenstein founded Grokker after she had a hard time searching for good yoga videos while on vacation even if she was willing to pay for them.
