Our Values
Provide Great Customer Service
We strive to be the most responsive vendor on your team. We want to be your partner and consultant for years to come, not just another company that sells you software.
Solve Problems
We believe in solving problems, especially the hard ones. We work closely with our customers to understand what they are trying to accomplish and to craft solutions that provide answers. We have a long and trusted relationship with the Precisely Software team, and have worked with the team that first developed the original MapInfo Pro. We bring this expertise into every customer engagement.
Invest In Industry Expertise
We work with all types of businesses and have solved a lot of data challenges over the decades. We know what works and what doesn’t, and we invest in keeping our technical expertise up to date. Our team has in-depth expertise from working with telecommunications companies, retailers, and government agencies.
Our Team
SGSI is a nimble and responsive team of software engineers, project managers and business analysts. Our small team works in an open floor plan to more easily share ideas and collaborate on solutions. SGSI has earned the Precisely Software Business Partner of the Year designation numerous times and are frequent contributors at conferences and workshops.
