Here's something for solution providers to consider as they try to navigate a challenging and fast-paced IT talent market: Your newest competition might not be the solution provider down the street, but a start-up founded by an ex-banker.

It seems bankers are saying goodbye to their big salaries in order to found tech start-ups focused on risk management, data analytics, trading platforms and other services in the finance vertical. A  Sunday Bloomberg story examines the trend in-depth.

At the core of the story is the fact that since 2008, banks and bond brokerages have shed hundreds of thousands of employees, and many who survived those days still aren't confident that they won't be next on the chopping block.

What they've found is an opportunity in tech, where demand for talent far outstrips supply. There are more than 500,000 open positions in software development, cybersecurity and other tech fields, according to McKinsey & Co. data that also put the number of start-ups in banking tech at about 12,000.

The pay? Not nearly the seven figures high-flying finance honchos can pull down, but Bloomberg quotes several execs who say they're much happier now that they enjoy what they're doing, feel like they're making a difference and in control of their professional lives.
