Shaping the Story of Software That Matters
Aviation. Agriculture. Life Sciences. We build where outcomes matter to people’s lives. Our teams are relentless question-askers and detail-obsessors who care about doing good work with good partners. Curiosity is our default setting; it shapes how we solve problems and how we build software the world relies on.
Our Story
Founded With Purpose
Founded in 1988, SEP has grown into one of Indiana’s largest software development companies, but size has never defined us. What matters most is helping clients build products that serve real needs, stand the test of time, and carry their mission forward.
Started by Rose-Hulman graduates, SEP was built on a simple idea: create a place where people can do their best work—a place where talent thrives, and support starts on day one.
From the beginning, we tackled complex, regulated domains including aerospace, defense, automotive, pharma, and heavy machinery. By the early 2000s, our work expanded into energy, banking, and medical devices. Today we work in fields as wide as construction design, entertainment, and financial services.

Employee-Owned
We earned our ISO 9001 certification in 2003 and continue to uphold it as part of our commitment to quality. In 2010, we became employee-owned, a milestone that reflects our belief in shared success. That same year, we ranked first among Indiana’s Best Places to Work—a recognition we’ve earned every year since.
Today, our 180-person team partners with organizations from Fortune 100 companies to growing startups. The values that shaped our earliest years still guide how we collaborate, how we solve problems, and how we build products with care—because when software matters to you, it matters to us.
Meet the People Behind the Work
When you work with SEP, you’re not just buying software services. You’re getting a team of people who make your big ideas possible. Our engineers, designers, and product experts bring experience, creativity, and discipline to every engagement, so you can count on outcomes that last.
“They can do it all.”
SEP’s career standards are off the charts. I love working with a team that truly puts the “p” in professionals. They can do it all. From modern design and agile practices to innovation, SEP has done it all for us. They are a full-service shop.
Leaders Who Inspire
Our team brings together diverse experiences, big ideas, and a shared passion for creating a place where smart people can do meaningful work and enjoy life outside of it.
Since we’re employee-owned, the work is personal. Every project reflects the people behind it, and every outcome matters to us in a real way. We measure success by the value we help create over time, not by quick wins or surface-level results.
SEP In the Community
Central Indiana has been a great home to SEP since 1988, and we want to give back to our community. Through employee engagement activities and grant and scholarship funds, we hope to live out our vision in an impactful and meaningful way.
