Toshiba Medical Systems of Japan recently closed a product deal with Israeli-based company Paieon — and geographically and figuratively, Boston-based Triangle Technologies Ltd. was the “middleman” that put the deal together.

Triangle is a niche company that brings together corporations in Japan with technology specialists in western countries, many of which are in New England.
It was founded by Daniel Isenberg, a Harvard Business School professor who teaches international entrepreneurship.

Triangle has done more than 100 deals in Japan in recent years.

Though the private company does not reveal its revenue figures, it often receives both commissions and equity from its long-range deals.

Triangle executives were responsible for Paieon’s initiative in Japan, including “forming the initial relationship with Toshiba, guiding the technical due diligence process, as well as negotiating the terms of the OEM agreement itself,” Paieon officials said.

Toshiba, which manufactures cathlab equipment, will integrate Paieon’s 3-D system into its echocardiography machine, providing real-time results in both diagnosis and treatment.

“Triangle is more than a facilitator,” said Isenberg, a Woods Hole native who earned a Ph.D. in social psychology from Harvard. “We see the business proposition and do what it takes to make it happen.”

Isenberg got involved in commerce in Japan in the early 1980s, when he taught case studies involving corporations there.

“In this country, some people think that Japan is not so entrepreneurial,” Isenberg says. “It really is, but it comes in a different form. You can’t say that corporations like Toyota and Honda haven’t been innovative and entrepreneurial over the years.”

He left Harvard Business School in the late 1980s and moved to Israel, the native country of his wife. Since returning to Harvard Business School last year, he has taken the title of chairman of the company while he teaches again.

The company employs 10, and also has offices in New York.

Close to 40 percent of Triangle’s deals involve companies in the life sciences. However, Triangle recently brokered a $4 million deal between Boston-area Application Security Inc. and LAC, another Japanese corporation, involving the security of large corporate databases.

Isenberg said future opportunities in Japan include deals that focus on mobile communication, and drug and medical-tool discovery.
