Pandora originally incorporated in 2000 as Savage Beast, Inc.

The Savage Beast is back. Pandora just updated its S-1 filing to go public with the Securities and Exchange Commission, upping its market cap from $1.3 billion to $1.9 billion, at $12 a share. Pandora's underwriters, who include Morgan Stanley, J.P. Morgan and Citi, must've realized the company would fetch more on opening day--and realized this sometime in the last week.

After the volatility of LinkedIn's IPO--which soared on opening day but then fell back to its initial price after investor hype died down and an innocuous but scary-sounding story about privacy concerns broke in the blogosphere--initial share pricing for (largely-unproven) web 2.0 companies is looking more delicate. Price too high, and you discourage buyers for a company with a $92 million net deficit whose admitted risks include that they "may not be able to achieve or sustain profitability;" price too low, and you leave money on the table.

The amended filing says Pandora plans to IPO as soon as the paperwork is approved, so we're not expecting any more changes to the pricing.
