"Product market fit is when your second employee is someone who& #39;s opening envelopes of money. eBay was such a good fit. Sellers were voluntarily sending in checks. Pierre had to hire someone, & #39;Hey, can you help me deal with all these checks that are coming in?& #39;" Modest Proposal https://twitter.com/patrick_oshag/status/1312850056727457795">https://twitter.com/patrick_o...

I remember meeting Bob Kagle at Benchmark in 1999 and talking to him about eBay. I don& #39;t recall anyone thinking that marketplaces would become as important a category as it would become. There were flops when a category didn& #39;t involve a hard buyer and seller coordination problem

After it& #39;s formation in 1999, Commerce One went from a $20B market cap to bankruptcy in a couple of years. Buyers and sellers bypassed it once they found each other and many already knew each other and found zero value. If you don& #39;t solve a real customer problem, you& #39;re dead.
