Tumbelweed cut its revenue growth target for 2001 to 50 percent to 60 percent over 2000 revenue, down from the previous expectations of 100 percent growth.
In a news release, Tumbleweed chief executive Jeffrey C. Smith said although the company had a good start to the fourth quarter, market conditions changed considerably in December.
As a result, the company will slash 20 percent of its work force and take a one-time restructuring charge in the first quarter 2001.
Smith also said Tumbleweed will change to a subscription-based pricing model in 2001. Smith said the new model would simplify the contract process, increase revenue visibility, and improve the company's cash flow.
