If you're looking for a model for how real change happens, I suggest you keep an eye on James Koutoulas.

A man of many hats, Koutoulas was recently catapulted into the headlines as the co-founder and lead attorney of the Commodity Customer Coalition, a grassroots organization established to help former MF Global (OTC: MFGLQ) customers reclaim their money after the broker's epic bankruptcy. The CCC's reclamation push has included the money that was in the broker's accounts at the time of the filing -- which was initially slow to be distributed -- as well as the $1.2 billion of customer money that vanished at some point prior to the bankruptcy.

What's fascinating about Koutoulas' role in the CCC is that though he is a lawyer by schooling, license, and suffix, it's not his day-to-day profession. And yet, here he is, smack in the middle of the nation's eighth-largest bankruptcy, representing more than 8,000 claimants and battling financial giants like JPMorgan Chase (NYSE: JPM), Wilmington Trust (a M&T Bank (NYSE: MTB) subsidiary), and Bank of America (NYSE: BAC) for more than $1 billion in funds.

A fresh face in a crazy case
Prior to his foray into the bankruptcy-court scene, you could find Koutoulas donning the CEO cap at Typhon Capital Management, a commodity trading advisor that he set up back in 2008. The culmination of Koutoulas' background in capital markets and computer programming, Typhon brings together talented traders and takes care of risk management, sales, and other back-office obligations that would otherwise distract them from trading. Typhon is then able to offer its investor customers tailored exposure to commodity and equity trading strategies.

Koutoulas described Typhon's model to me as similar to object-oriented computer programming -- that is, he takes efficient individual components and makes them movable and reusable. The structure fits Koutoulas' personality perfectly, as he's nothing if not pragmatic.

Which brings us back to MF Global.

With tens of millions of Typhon's assets sucked into the bizarre vortex of MF Global's multifaceted failure, both the company and James Koutoulas were automatic participants in the brouhaha over the supposedly segregated customer money. From day one there was a lot on the line for Koutoulas, but that hardly necessitated him taking on the role of William Wallace for thousands of others wronged by MF Global.

So why dive into the courtroom drama, take time away from his business, and sacrifice countless hours of sleep? When you ask him, the answer is exceedingly simple.

"No one else stepped up," he told me. "My personality is very problem-solving driven. I could sit by like others and go out of business or I can do something about this."

Fighting the good fight
With so many unanswered questions still swirling in the case, it's a bit premature to try to come up with too many lessons from the situation. Yet I couldn't help but ask Koutoulas what he's taking away from the mess at this point.

"Never stand down," he quickly replied. "If somebody is trying to take advantage of you, stand up for yourself."

It's an attitude that a few years ago would have seemed unusual -- maybe even naive -- when it comes to fighting the behemoths of the banking world. Perhaps critics could say that makes sense; after all, Koutoulas just turned 31, and a cynic might assume that he doesn't know any better than to take on the likes of JPMorgan and B of A.

But that's far from a Foolish attitude. That wasn't what drove The Fool's involvement in getting Regulation Fair Disclosure passed, it wasn't how we approached our in-depth look at MF Global, and it's not the mind-set that Rich Smith has had in rallying support for the Stop Trading on Congressional Knowledge Act. It also echoes the voices of thousands of Occupy Wall Street protesters standing up to Wall Street and the thousands of customers who pushed back when big banks tried jacking up their fees.

And it's an attitude that has yielded results for Koutoulas and the CCC. That "never stand down" approach has helped the coalition "educate" bankruptcy trustee James Giddens -- a hotshot in the legal bankruptcy world and the trustee for the Lehman Brothers case -- about the commodities industry and the plight of MF Global's commodity customers. These efforts appear to have helped speed up the return of a sizable chunk of customer money. The group's push has also put pressure on MF Global's primary exchange, CME Group (NYSE: CME). CME's efforts to date have underwhelmed many involved in the mess, but it has offered up a $550 million guarantee to help hurry along the return of customer money.

JPMorgan and the road ahead
If you talk to Koutoulas, it becomes clear very quickly that the main Goliath to his David right now is JPMorgan.

"Their hands are on every aspect of this case," he told me. He went on to explain that JPMorgan was the custodian for MF Global's segregated customer funds and the company's biggest lender. He also has concerns that the bank got preferential treatment in its purchase of European sovereign debt and a stake in the London Metals Exchange from the MF Global estate. And now JPMorgan is swooping in as a vulture investor, offering to buy funds claims from customers at a significant discount. The phrase "conflict of interest" hardly seems sufficient to describe JPMorgan's involvement.

While Koutoulas' more candid views on JPMorgan aren't exactly fit to print, his actions are. Through the CCC and his widely followed Twitter account (@jameskoutoulas), he's been advocating a full boycott of JPMorgan -- banking, mortgage loans, credit cards, prime brokerage, you name it.

Never back down.

At the end of the day, it's all about the freedoms we have living in the U.S. "I can say whatever I want as long as I'm not slandering," Koutoulas reminded me. And that includes taking on big-money interests like JPMorgan. "Consumers still have a choice and they can vote with their feet."

It's certainly not an easy road that James Koutoulas is walking, but if we're going to see change -- whether it involves the MF Global bankruptcy and the U.S. futures market, members of Congress trading on non-public information, ineffective public-company boards, overpaid executives, or the myriad other issues that we deeply care about -- we can certainly learn a thing or two from his willingness to fight.
