About
A small, focused practice.
Led by Brandon Johnson, based in Minneapolis.
Brandon started the practice in 2018 after three years as a research engineer at space150, where he developed a love for fast-paced, high-quality, client service work and shipped his first React Native apps. He studied journalism and computer science at the University of Minnesota — a combination that still shapes his work to this day.
