Coffee chain Mojo has caught the attention of some high-profile All Blacks in its pursuit to conquer the United States cafe scene.

The Kiwi rugby stars are among a group of 15 international rugby players, current and retired, setting up an investment company to buy into the business.

Last year investment company ADP Investments, set up by Brett Gamble and rich-lister Ben Gough, bought a 35 per cent stake in Mojo after plans for Cooks Global Foods to buy the company for $19 million fell through.

Gamble said ADP Investment's stake in the business had grown to 57 per cent over the last six months.

Gamble did not reveal who the players were, but said this would be announced within the next month.

US investment company Soulcaster also recently bought a 13 per cent stake in Mojo.

"It really is nice to see a range of different investors recognising the opportunity in Mojo. They love the New Zealand export opportunity. The backing of a US-based investor gives some quantum and justification for what we're doing.

"And it's great having high-profile rugby players involved because they have great brands they can attach to the business."

The coffee chain was opening its fourth cafe in Chicago, two years after launching in the US.
