Five venture capital firms are going to wake up stinking rich on Wednesday, thanks to the successful IPO of Pandora, which operates an Internet music sharing service. As a group, the five firms own 105.6 million shares, which are worth $1.69 billion at the IPO price of $16 per share. And they’re not the only ones. The Hearst Corp. is sitting pretty, too, as are Pandora co-founder Tim Westergren and several other insiders.

Of course, this is all theoretical, since the VCs and Pandora’s officers and directors are locked up from selling any shares for 180 days. Assuming the stock holds steady when the lock-up ends in six months, here’s how Pandora’s top 10 largest shareholders will make out.

No. 10: Peter Gotcher
