Founder · Product & technology
Andrew Branning
Leads the Solidus vision and turns the day-to-day needs of range operators into practical, connected software.
The people behind Solidus
Built by range owners. Tested at the counter.
Modern tools, practical experience, and a shared purpose: help gun ranges run well and grow.
A better next chapter for the modern range.
Andrew Branning founded Solidus One with a clear purpose: bring enterprise-grade tools to gun ranges, helping owners manage compliance and create more opportunities to grow revenue.
His business partner, Alexander “AJ” Rossi, owns Lowcountry Guns & Range in Hardeeville, South Carolina. Together, they are building and testing Solidus inside a working range, where daily operations shape the product.
From the first waiver to the next visit, the goal is simple: help owners serve their customers, keep records organized, and build a business people return to.

A NAME ROOTED IN VALUE
The meaning behind Solidus
A name with weight. A purpose that lasts.
The solidus was a gold coin of the Roman Empire. Surviving examples, including coins bearing Constantine I, connect the name to a tangible measure of value.
For us, that name is a reminder of what business software should contribute: a stronger foundation, clearer operations, and opportunities to grow. We’re building Solidus to help range owners create lasting value in their businesses.
Our team
Built with people who know the work.
Solidus brings product and technology experience together with the working knowledge of the Lowcountry Guns & Range team. Their perspective helps keep the software grounded in real range, training, and pro shop workflows.
