About Me

I am an investor, advisor, radio show host and entrepreneur.

I’ve been helping and advising tech entrepreneurs in the mobile telecoms and brand marketing space since the late 1990s. In that time, I’ve traveled to over 40 countries on business. Business is an adventure, join me on the journey.

Active investments include real estate, mobile telecoms, endurance sports retail, online gaming and a craft brewery.

I’m currently focused on Asian based projects, particularly working with entrepreneurs looking to expand into new markets.

Founder FM

Founder FM is a radio show for entrepreneurs and investors.

I regularly interview interesting and inspiring entrepreneurs about their startup journey. Entrepreneurs come in all shapes and sizes, not just the classic Stanford computer science graduate we’re so accustomed to in the media. I’m interested in the stories of the outsiders, entrepreneurs who overcame significant challenges and these are the stories I share on Founder FM.

A Little Backstory

Location Independent Entrepreneur

Following a business exit, we traveled the world for 3 years non-stop between 2012 and 2015.

It was our family adventure.

We traveled through New Zealand, Japan, Fiji, Hawaii, California, Florida, Cyprus, Fuerteventura, Lanzarote and Okinawa.

It was also a mini-retirement. I exited a telecoms business of 12 years and traveled on my investment income. It was a bit of head space for me to explore my writing and show my son the world. Sure, people thought we were crazy but then (as Helen Keller once said), life is either a daring adventure, or nothing at all.

We lived extended periods on the sub tropical islands of Lanzarote (Spain) and Okinawa (Japan). We loved island life. Lanzarote was a great place for outdoor living and provided a base for me to train for and complete the Ironman triathlon (see pics below). The Lanzarote Ironman is listed by as “one of the 10 toughest endurance races in the world.”

The thing about this lifestyle is …the highs are higher and the lows lower. So, after 3 years of living out of suitcases we decided to settle down. We now live outside of Tokyo.
