David Heinemeier Hansson:

Groupon has filed its S-1 and hopes to raise $750M in its initial public offering. Given they’re currently losing a staggering $117M per quarter, despite revenues of $644M, they’ll be burning through that cash almost as soon as it hits their account.

At the moment, it’s costing them $1.43 to make $1, and it doesn’t look like it’s getting any cheaper. They’re already projected to make close to three billion dollars in revenues this year. If you can’t figure out how to make money on three billion in revenue, when exactly will the profit magic be found? Ten billion? Fifty billion?

No bubble here. (via Gruber)
