Root Causes
Fab.com was a design-focused flash sales site that grew to 10 million users and raised $336M. The company was spending $14M per month at its peak, with CEO Jason Goldberg frequently pivoting the business model: from social network to flash sales to full-price e-commerce to European expansion to… custom furniture. Each pivot burned more cash without achieving sustainable unit economics. The company laid off 75% of staff, sold its European operations, and was eventually acquired for a reported $15M—a 96% loss for investors.
