Workday’s IPO is doing well, with its stock price rising from the $28 per share debut to around $50 per share. Dan Primack has broken down the potential payday for the VCs that got in on Workday’s earlier rounds, and his back-of-the-envelope calculations put Greylock’s cut at around $744 million on an $82 million investment; New Enterprise Associates’ at around $683 million on a $46 million investment; and four other firms standing at around $92 million each, on a collective $100 million investment.
