In tech companies, thinking is the primary activity and the core process used to create value. One of the challenges when thinking about technology is keeping up with constant innovation and envisioning what will evolve next. To stay abreast of emerging technologies, I've built an ecosystem of entrepreneurs, engineers, scientists and investors who have innovative ideas. We are interested in AI, Computer Vision, Biotech, Precision Medicine, and Blockchain. Like a natural ecosystem, my ecosystem consists of interlinked resources that complement each other. I have over 14,000 people from over 30 countries in my community so far. As my community expands, the value of the ecosystem increases exponentially. These are some of the entrepreneurs, engineers and investors in my ecosystem with whom I collaborate regularly.

Margaretta in a word is awesome. I have been fortunate to know her for a number of years and work with her on startups and non-profits. We serve on six advisory boards together and I hear nothing but high praise for her work effort and strong ethics. Margaretta is intelligent and creative. She works hard and smart. She thinks long-term and has an innate ability to execute on near-term projects which will lead to future success. She's a constant learner and reader which leads her to explore and find connections which are pertinent but were not previously thought of by others. When she works on a project, she focuses on it but also allows her mind to think through other permutations about how it could be done. Margaretta doesn't seek the spotlight. She works well with other people and she isn't looking for the limelight.

Margaretta is a very pure person. She is one of the most advanced, balanced, and harmonized people I have ever met. She has high levels of IQ + EQ + LQ + Erudition + Energy + Charisma. She also has high levels of personal performance, dedication, and focus. She is the best partner and friend to have when you want to convert a bold idea that others consider undoable, unthinkable, and impossible, into reality. With Margaretta, it actually becomes a reality. In addition to what I've said, I also concur with what other people say about her here.

I was part of the team that recruited her in 2003 to be Director of Sales and Marketing at our company on Wall Street in New York. Margaretta was the single most successful sales director in our company history. Her tireless and laser focused efforts and professionalism brought us tremendous business and amazing new clients and partners. She single handedly brought in big accounts including: Barclay's Global, Standard and Poor's, NCR, Teradata, MITRE, Countrywide Financial, Enterprise Rent-a-Car, JP Morgan, Portland Gas & Electric Company, Pennsylvania State University, JBoss and Red Hat.

Margaretta and I met at the intersection of AI, Big Data, Clinical Medicine and Drug Discovery. Our complimentary backgrounds and respective networks suggest that we have a bright future of collaboration ahead of us. I count on her to get the latest scoop from Silicon Valley, plus crucial advice on AI projects, start-up funding and strategy, while providing her with my take on the French and Spanish innovation scenes. Having worked in some of the world’s most vibrant Biotech hubs (Boston, San Francisco and Barcelona), I know how important it is to surround yourself with doers, like Margaretta, rather than just talkers. Chatting with her is a refreshing reminder of how easy networking can be when people start with a positive attitude and an open mind. I look forward to Margaretta becoming a true mentor.
