About QOLOS
We partner with forward-thinking companies to develop software solutions that save time, reduce costs, and elevate customer satisfaction.
Our Story
QOLOS is a U.S.-based software development company founded in 2018 by Chad VanCalster, following the sale of his previous agency.
We bring together product thinking, technical expertise, and a hands-on partnership approach. Our focus is on enterprise commerce, connected business systems, and custom software that makes complex work simpler.
From a single integration to a large custom software initiative, we work alongside your team to build the right solution for your business—and keep improving it as your needs evolve.
Our Founder
Founder of QOLOS
Chad has founded 4 companies and completed 2 successful exits, including a digital agency and a software company. With more than two decades in technology, digital strategy, and product development, he brings an owner’s perspective to the work—not just a technical one.
Building, growing, and selling businesses gave Chad firsthand experience with the challenges his customers face: leading teams, scaling operations, and deciding where technology will deliver a meaningful return. That experience shapes QOLOS’s focus on saving time, making daily work easier, and keeping projects moving smoothly.
His expertise spans ecommerce architecture, ERP integrations, custom software, and business systems. Today, he works with the QOLOS team and customers to connect existing platforms and build new systems that extend what those platforms can do—from SAP and Infor integrations to Salesforce development and Shopify and BigCommerce solutions.
Chad’s approach is straightforward: understand the business, make complex problems clear, and build practical solutions that keep delivering value as the company grows.
