Who we are.
Londonberry is Ben McDonald: fractional CTO and founder, 25 years of engineering judgment, backed by a stack of AI agents, based in Jacksonville, FL.
What's Up With The Name?
It started on a street in Atlanta.
When it came time to name the company, I started thinking about joy: the kind of joy that's a remnant of less stressful days, like the ones we had as kids.
The thrill of riding a big wheel down a steep driveway. A neighborhood game of flashlight tag on a summer night. The triumph of learning to ride your bike without training wheels.
I experienced all of those feelings growing up on a street named Londonberry.
Ben McDonald
Fractional CTO & Founder
I founded Londonberry in 2010 after leaving the management team at Hashrocket to go out on my own. After several years of consulting, I spent nine years as a technology executive before coming back to what I love: building software and helping others build it better.
Today I serve as fractional CTO for founders shipping AI-native products, and run vibe coding rescue engagements for teams stuck between a working AI-generated MVP and a production-grade product.
Today, Londonberry is a one-person shop amplified by AI. I use AI agents and AI-assisted development tools daily, and that's exactly what makes it possible to deliver at the speed and quality of a much larger team.
I'm based in Jacksonville, Florida and I'm passionate about improving the local tech community, helping startups find their footing, and building software for the sports world.
