Great people, processes combined with a knack for innovation and excellent product design. The ability to see the winds of change in technology and innovation and to see things not as they are, but as they can be, and bring your reality to exceptional realization.
From Inc Magazine: Perhaps the biggest break came when SnapNurse* hired Edwin Marcial as interim CTO … Marcial had built the technology behind Intercontinental Exchange (ICE), the powerful Atlanta company that acquired and operates the New York Stock Exchange. Hiring the guy who built one of the world’s fastest trading systems proved to be critical; the infrastructure Marcial and a team of ex-ICE engineers created for SnapNurse was highly flexible and scalable.
*SnapCare was formerly known as SnapNurse
SnapCare* - #2 on the Inc 5000 fastest growing private companies in America.
