Mandelbrot Project, a stealth startup led by former DailyCandy CEO Pete Sheinbaum has raised $500,000, according to an SEC filing. PEHub says the backer is the Foundry Group, which declined to comment. Sheinbaum oversaw the $125 million sale of DailyCandy to Comcast (NSDQ: CMCSA) Interactive in August 2008; he left Comcast in May. At the time, he told us that he would be “looking for some new opportunities either helping existing companies or perhaps another startup, utilizing what I have learned along the way.” (For those wondering, Mandelbrot is a type of almond bread, although it could also refer to the mathematical term).
