Digital Guerrilla Build Digitally

Scotland's First Information Management Consultancy

At Digital Guerrilla, we believe that innovation starts with challenging the status quo. Founded as Scotland’s first Digital Information Management consultancy, our mission is simple: to empower the construction industry with smarter, more efficient digital solutions for every day problems, from design to data, costing to handover.

We live by the principle that great solutions start with deep understanding. Just as Einstein valued time spent defining the problem, we invest in uncovering the real challenges behind your processes before proposing digital strategies. By focusing on clarity and insight, we ensure that every solution we deliver isn’t just fast—it’s the right one.

“If I had an hour to solve a problem I’d spend 55 minutes thinking about the problem and 5 minutes thinking about solutions”

Albert Einstein
