Making teamwork with clients calm and contained.
We build the workspace we wanted for our own client work — chat, tasks and files together, with a door you can open for each client and close again.
Built by a team that works with clients every day.
Tandem App began as the internal tool of a software team that was tired of client work being scattered: decisions in one chat app, tasks in another, files in a shared drive and the client copied into long email threads. Adding a client to the team chat meant showing them far more than they needed to see.
So we built one workspace where every channel has its own conversation, task board and file store, and where a client can be invited into exactly one of those channels — with the access you choose, until the date you choose. After using it ourselves, we opened it to other teams, with a free plan for small ones and simple per-user pricing after that.
Tandem App is a project by Softech UK.
The principles behind every channel.
Least privilege
People see what they need and nothing more. Guests see their channel; nobody sees an email address they shouldn't.
Honest pricing
Every feature on every plan. You pay for your team, never for your clients.
Your data is yours
We use it only to run the service. Export all of it whenever you want.
Simplicity
Familiar chat habits, a task board that needs no training, folders that behave like folders.
Careful by default
Two-step sign-in for owners and admins, separate workspaces, and permissions respected everywhere.
Room to grow
Free for small teams, fair per-user prices after that, and an easy way in from Slack.
Work with your clients, not around them.
Set up your workspace in a minute. Free for up to 3 users.
