Rob Gabel, formerly an executive at companies like LowerMyBills, Netflix and Machinima, is in the process of closing a $500,000 seed round for his new venture Tubular Labs, an SEC filing reveals.

The service is currently password-protected and thus presumably available only in private beta, but the company will basically provide marketing and analytics tools that help brands increase and engage with their audiences on video site YouTube.

Gabel was formerly SVP of Marketing of LowerMyBills, which was sold to Experian in 2005 for $380 million. He went on to become chief of marketing at Machinima , a Google-backed entertainment network for video gamers, and was briefly employed as VP of DVD Marketing at Netflix.

Also mentioned in the filing are LowerMyBills founder Matt Coffin and Machinima chairman and CEO Allen DeBevoise, who probably invested in Gabel’s next gig.

Another Tubular Labs backer is Ben Smith, a serial entrepreneur and angel investor.

Listed as co-founder of Tubular Labs on LinkedIn is Allison Stern, who previously worked at 20th Century Fox, AOL, Google and YouTube.
