Virool, a year-old San Francisco-based video advertising startup, has closed on $6.62 million in funding from a long list of investors in what the company claims is the biggest seed round raised so far by a graduate of the the Y Combinator incubator program. (Virool came out of the program last summer.) The company’s institutional investors include Draper Fisher Juvetson and Menlo Ventures; individuals who contributed to the funding include Paul Buchheit, Dave McClure, and Yuri Milner.

Comprehend System Inc. has raised $1.2 million in seed financing from a slew of investors including Y Combinator, Start Fund, SV Angel, Yuri Milner, Menlo Ventures Talent Fund, Paul Buchheit, Garry Tan, Quotidian Ventures and Crosslink Capital. The company is developing clinical data visualization and analytics software.

Interesting post just published by Paul Buchheit, best known for creating Gmail as Google employee no. 23, and cofounding the social network aggregator FriendFeed, acquired by Facebook last summer under undisclosed terms.

Titled “What To Do With Your Millions,” it’s Buchheit’s response to the post of someone newly rich on Hacker News who is, in Buchheit’s view, receiving crummy advice (this comment notwithstanding).

Buchheit’s first bit of advice, do not hire a financial advisor, no matter how many times friends recommend you to exactly that. “What those people don’t understand is that the only skill a financial advisor needs in order to be successful is the ability to sell you things,” writes Buchheit. “Their actual financial skills are almost irrelevant.”
