Team.

The people behind the studio — the work on the walls, and the platform behind the screen.

  • Keith Killebrew

    Keith Killebrew. Founder & Owner.

    Fine art painter and muralist working in oil and acrylic from a studio on the Cumberland Plateau in Tracy City, Tennessee. Keith founded the studio practice and leads every commission, workshop, and mural project.
  • Iain Feeney

    Iain Feeney. Website & digital · Founder and CEO, Stacklumen.

    Iain Feeney founded Stacklumen and leads it as Founder and CEO. Iain runs product, design and engineering across the company's products, and works directly with the clients and partners Stacklumen builds with.

    Iain came to software from public service and operations. Iain spent about three months with the Memphis Police Department, two of them as a Police Recruit, completing eight weeks of firearms, constitutional law and emergency vehicle operations (EVOC) training before leaving to pursue work in the private sector. There, Iain served as an Armed Security Operations Manager, running security operations where preparation, procedure and accountability are not optional. That background still shapes how Iain runs a company: plans are written down, responsibilities are clear, and every problem has an owner.

    Iain also spent about two years at SpotOn as a Technology Sales Representative in Lexington and Memphis, selling restaurant technology and helping develop it. Listening to what restaurant owners actually need, and to why a product does or doesn't earn a place in their work, is part of why Stacklumen builds the way it does.

    Iain is a Licensed U.S. Soccer Coach and coached for three years in Memphis.

    Iain graduated summa cum laude from Berea College in 2021 with a degree in political science, receiving the C. Louis Smith Award and the Albert G. Weidler Award for excellence in political science scholarship. Iain is now a Senior MBA Candidate at American Military University.
