Documented cause
Chemdex was a B2B online marketplace for life science products backed by Ventro Corp, raising $400M from investors including Glaxo SmithKline. The platform took 4% transaction fees but chemical suppliers refused to share margin and began setting up competing portals. After burning $600M, CEO David Perry was removed in 2001. Ventro's market cap fell from $8B to $58M in 14 months; the B2B exchange was shut in October 2001 as the model collapsed industry-wide.
Lesson
“B2B marketplaces must deliver supplier-side value first; intermediating incumbents always provokes retaliation.”
