Santa Clara, Calif.--Beyond.com lost its founding president-CEO, Mark Breier, on Wednesday as part of the consumer company's shift to business-to-business. Mr. Breier said he'll work as an adviser to Internet start-ups and invest in dot-com companies. Beyond.com named CFO Rick Neely interim CEO. The company announced it will eliminate 75 jobs, about 20% of its work force. Beyond.com was attempting to sell software to consumers and businesses, but high marketing and fulfillment costs led to losses of $90 million in the first nine months of fiscal 1999. The company said it will take a $2 million-to-$3 million charge as a result of the restructuring.
