Entrepreneurship the answer to all of society's problems.

This may sound cliched to some, but for Daniel Epstein, it is a personal mantra.

Mr Epstein, the founder and CEO of the Unreasonable Group, has created a portfolio of companies dedicated to unleashing entrepreneurial potential to solve difficult social problems.

These companies include a regional accelerator programme known as the Unreasonable Institute, a series of investment funds under Unreasonable Capital, Unreasonable Media, which is dedicated to telling the narrative of entrepreneurs and an around-the-world voyage known as Unreasonable@ Sea, which is dedicated to helping entrepreneurs enter international markets with later-stage companies. He is also the founder of a resource site Unreasonable.is, and an adventure travel and ecotourism website known as Unreasonable Adventures.

The Unreasonable brand name may seem unusual for a group trying to develop entrepreneurship, but Mr Epstein has a reason for this.

He draws inspiration from a quote by George Bernard Shaw: "The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man."

The rationale for Mr Epstein and his team is that if Shaw were right, if all progress depended on the unreasonable person, then as a company, they cannot afford to not bet on unreasonable people.

Mr Epstein is himself someone who might be worth betting on.

Still under 30 years of age, and a college student until only a few years ago, he was recognised by Inc. magazine as a "30 under 30 entrepreneur" and by Forbes as one of the "top 30 most impactful entrepreneurs" of the year in 2012.

His journey began as a result of a social problem that he wanted to solve for himself and other like-minded individuals, he tells The Business Times.

In his freshman year at university, Mr Epstein had already started three companies, which he explained were targeted at solving complex social problems.

Ironically, by the end of the year, having worked on these three start-ups, Mr Epstein said he started feeling like a misfit as he had no social circles to "hang out with".

"So, at the end of the day, the genesis of the Unreasonable Institute was a desire to seek refuge among the misfits, to have a community of entrepreneurs who were trying to solve problems, which solutions had no precedence," he explained. The institute ran its first pilot programme in 2008, working with early-stage entrepreneurs by bringing them together for six weeks in a college accommodation building in Boulder, Colorado, to address their start-up concerns.

Mr Epstein said that he and his team saw the opportunities after this pilot run and decided to expand.

Today, they annually bring together about 20 young entrepreneurs in an accelerator programme mentored by 50 notable individuals. These mentors have included famous personalities from a wide variety of fields, such as Archbishop Desmond Tutu.

Mr Epstein aims to expand the institute into regional markets and have 50 institutes in 50 countries by 2020.

He was recently in Singapore to participate in the World Entrepreneurship Forum, where he was one of the six recipients of the 2013 Entrepreneur for the World award.
