An anonymous commenter on VC scandal sheet, with the appropriately frat-boyish screenname "jagrmeister721," has lashed out at Sierra Ventures VC Jeff Loomans. Loomans's portfolio includes Corrigo, Grayboxx, MIOX, Red5 Studios and Zoom Systems. The entrepreneur writes:

Dealing with Jeff Loomans, his dishonesty and malicious behavior for a year and a half has been a headache. In some ways, I am glad to part ways because I have never dealt with someone who seemed to relish petty power-plays and lying on a systematic basis as much as he obviously did.

Sierra had requested that he write a positive review, he says — a common enough practice for VC firms trying to buff their image on Be careful what you ask for.
