JPMorgan, Goldman Sachs, Morgan Stanley execs talk tech

The world's biggest financial institutions are spending billions on technology.

And, as I wrote in a weekly note to BI Prime subscribers on Sunday, the industry is reaching an inflection point where those massive investments are starting to pay off.

But challenges remain. There are new startups posing fresh competition. There's a talent war with Silicon Valley. Customer expectations are evolving. And there's the cultural challenge of driving innovation in huge organizations that have been around for decades and operate in a tightly regulated industry.

Business Insider hosted IGNITION: Transforming Finance at the New York Stock Exchange on Monday to discuss all of this and more. Here are the highlights.
