I heard the one startup spent one round of funding buying Aeron chairs. The number of chairs was taken as indicator of the founders' certainty in the venture and this led to a larger round of investment. Antics like this led to the Aeron chair ratio for failed startups. Apparently, some failed startups had more 10 Aeron chairs for every employee.
