Company
Usable Software LLC
A small Massachusetts software company. We build one product, TCS, and we build it for teams whose work has outgrown the tools they were handed.
What we do
Usable Software LLC develops and operates TCS, the Team Coordination System: a system for tracking work, where each team decides what its work is called, what it needs to know about it, and what it can leave out.
It is built for people who are already doing the work. It meets them in their own words, with the fields they actually use, instead of asking them to change how they work to suit the software.
How we work
- One product, done properly. We would rather one system be genuinely usable by four different kinds of team than ship four thin ones.
- Your data stays yours. Each organization's work is kept separate from every other's, and your files can stay in your own storage rather than ours.
- No surprise dependencies. No ad networks, no third-party analytics in the product, no tracking pixels on this website.
- The strict cases first. Teams working under GxP have the least room for a record that cannot be explained, so their requirements set the floor for everyone — and integration with the systems a team already depends on is worked out with that team, not assumed from a list.
Who we are
Usable Software LLC was founded in 2026 by Paul Ruseau, who writes the software. His background is in human factors — the study of how people actually use the things built for them, and why so much of it fails at the desk of the person doing the work.
That is not a garnish on top of the engineering. A system can be complete on paper, pass every test, and still be the worst part of somebody's day. Deciding what a team should never have to look at, and what words it should see instead, is the design work — and it is the reason this company has the name it does.
