about uncle louis

We’re building for the next-generation.

Uncle Louis is the product of our belief that when systems are elegant, teams move better - every time.
We didn’t start Uncle Louis because we wanted to build another AI tool. We started it because we were tired of how modern tax teams were being forced to work. Endless research. Bloated software. Memos scattered across drives, buried in emails, delayed by revisions, or lost in chaotic workflows. It was never a tax expert problem. It was a systems problem. Most tools try to fix complexity by adding even more of it - new modules, new dashboards, new steps that slow everything down.

We knew there had to be a better way - one that simplifies instead of overwhelms. So we built Uncle Louis: a platform that supports tax decisions quietly and intelligently, reduces friction, and brings clarity to every case, document, and workflow.
