“Two and a Half Men” star Ashton Kutcher is a man determined to get his hands dirty in the tech industry, dirty with cash rewards when his investments pay off.

His latest investment is in payments startup Dwolla where he has invested an undisclosed amount of money in a company that is seeking to take the payments industry by storm.

Dwolla works by charging a fixed commission of 25 cents on transactions, rather than a percentage of the transaction value, as is the norm with all other payment systems.

The company, which operates out of Iowa, has already raised $5 million from other sources but has declined to reveal how much Kutcher has invested in the company.

The amount must be significant, nonetheless, owing to the fact that Dwolla CEO and founder Ben Milne, said he talks with Kutcher via Skype every month or so.

Milne says Kutcher’s insights have “shown up in the product already in a million different ways.” This shows the investment must be significant to merit such patronage from the star.
