Envivio shares tumble 50 pct on guidance cut

Analysts were already discounting the company's predictions, and had expected revenue of $10.7 million.

The experienced a slowdown of major project start-ups and a lengthening of sales cycles stemming from the current global economic environment.

Envivio plans to release its full quarterly results on Sept. 6.
