Some decisions have three awkward properties at the same time. There are far too many possible answers to check by hand. The answer has to obey strict rules. And it has to arrive before a particular moment, or it is worthless — however good it would have been.
Two real examples. A wealth manager runs fifty thousand individual investment accounts. Every night, before the market opens, each one needs its own list of what to buy and sell — respecting that client's tax position, restrictions and risk limits. Miss the open and the trades don't happen. Separately, an electricity grid operator has thousands of batteries spread across a region. Every few seconds, each one needs a new instruction as power prices move. The grid does not wait; miss the moment and the opportunity is gone.
These two look nothing alike. Underneath they are the same problem: search an enormous number of options, obey every rule, and finish on time.
PRISM is the software that does that. It returns an answer that breaks none of the rules, is as close to the best available as makes any practical difference, arrives inside the deadline, and comes with a record of how it was reached — so an auditor or regulator can check the decision later. Run it twice on the same inputs and you get exactly the same answer.
The honest short version. Existing tools already solve these problems well at small scale. They struggle when the number of accounts, assets or devices gets large and a hard deadline applies. That gap is the only thing we sell into — and where we don't win, we publish that too.
