Who We Are

Tamarin Software was founded on a simple belief: technology should help people understand one another more clearly, not create more confusion.

The idea began at 30,000 feet in the cramped middle seat of an airplane. Ann CB Landis — a strategist and writer who thinks in words — was frustrated with her design team. Her company was winning web projects steadily, and Ann understood both the clients and their goals. But the more detailed her creative briefs became, the harder it seemed for the designers to understand what she was trying to communicate.

The designers were frustrated too. Ann’s carefully written briefs felt like walls of text. They thought visually and spatially; she thought structurally and narratively. Everyone was intelligent. Everyone cared. But they were processing information differently.

That experience sparked a deeper realization: people make better decisions when information is presented in ways they can actually understand.

That philosophy became the foundation of Tamarin Software.

Today, Tamarin helps organizations build more accessible, sustainable, and human-centered digital systems. Our work spans accessibility strategy, accessible documents, ADA and WCAG guidance, digital process improvement, and communication systems designed to support diverse teams and audiences.

We believe digital access is a human right. Good systems should reduce friction, expand participation, and adapt to different ways of seeing, navigating, understanding, and interacting with information.

Because technology works best when it works for everyone.
