About KIS Solutions

Too often corporate IT teams and business counterparts are at odds. This is in large part because technologists too often focus on the technology solution itself rather than the underlying business problem. At KIS solutions we believe that technology is a tool to solve business problems. We focus on the business problem and operational processes which our solutions support. When building technology systems, the most challenging part of the development process is often deciding “what to build” not “how to build it”. It is sadly true however that many corporate IT teams spend so much their time focusing on the “how” rather than the “what”. Once you have answered the challenging questions around “what to build”, the rest falls into place. Building the system should be simple! Founder Benjamin Quintana is an IT professional and entrepreneur with nearly 20 years of experience delivering impactful solutions across a broad range of industries. Ben has extensive experience with customer data analytics, data cleansing, customer identification, customer preference management, call center and logistical systems. He also has deep industry expertise in loyalty marketing applications and was directly responsible for the infrastructure of the loyalty program of a leading hotel group.
