About

I am the founder of Expert DOJO , one of the most active institutional investors in the world. With over 300 startup investments I am uniquely positioned to speak to how startups grow from that initial innovation to a world dominating brand. My expertise is in the area of emotional resonance and how relationships can be built and sustained between those startups and their customers.. All my experience in Expert DOJO opened the door to both invest in and to become co-founder of Matchbook AI. Matchbook is an innovative SaaS solution that solves data quality problems by streamlining the process of matching and enriching data. Matchbook gives our clients the tools to unlock the value of their business with comprehensive data stewardship functionality and the world’s premier source of commercial intelligence from Dun & Bradstreet and other data providers.

  • Your Office Agent is an innovative Workplace Marketplace helping small, medium and large sized businesses find their ideal workspace. We provide our customers with a total workspace solution whether for home workers, mobile workers or full time office workers. Our solutions range from helping 1 person looking for a start up low cost image to the CEO of thousands of company employees who want to benefit from the efficiencies of new working methods such as hot-desking, desk-sharing, co-working, home-working, part-time office working and fixed leases. To help our customer adapt to an ever changing economy and workforce, we provide workspace options from a day to 5 years. As your one stop marketplace, we are dedicated to helping you find the best solution both locally and in any of the thousands of locations we have listed anywhere in the world.
  • The nice thing about our service is that, for a basic property search, there is no cost to the client, however after our relationship starts our real value is reducing costs, saving time and avoiding mistakes. As a local and global advisor, I am there for you whenever you need me. That, as well as our depth of workspace knowledge and our one view property and data approach, makes us truly unique in an industry where there are too many options and too little direction for the end user.
