Gobbler

• Total Equity Funding: $6.33 million
• Celebrity Investors: John Legend, Elton John, Jared Leto, Troy Carter, Ryan Tedder

No, Gobbler is not a turkey farm for the Hollywood elite — it's a digital subscription service for professional audio engineers, offering a rotating slate of audio software for a flat monthly fee. Given the company's emphasis on collaboration among music makers, it's little wonder that John Legend, Elton John, Jared Leto, Troy Carter (entrepreneurial manager to Lady Gaga) and musician-producer Ryan Tedder all jumped in early on seed funding rounds that raised over $3 million from early 2011 to late 2014.
