Goldman Sachs Has Started Giving Away Its Most Valuable Software

See the thread I referenced, which has comments that theorize why allowing others to use parts of it could be of value to GS.

The overall system is of such fantastic value it's hard to overstate it. GS can in a matter of minutes/hours play "what if" games, and otherwise determine risk and figure out what their position is, when other companies at worst depend on people manually scraping data from spreadsheets and submitting that upwards via email. Played a major role in their minimal losses during the last financial crisis, it's a crown jewel in their industry.
