Why ShellStack
The products handle the work. ShellStack handles the organisation behind it: who belongs, what they can use, where they work and how the suite is paid for.
Invite a teammate, assign their role and choose the apps and workspaces they need from one place.
One membership. Deliberate access.
Give clients, projects and teams a clear workspace home while access stays scoped as the suite grows.
Shared workspaces. Clear boundaries.
Manage plans, seats and subscription details for the whole suite instead of maintaining a separate account for every app.
One bill. A clearer view of spend.
The work suite
Each product stays focused on its work. ShellStack carries the people, workspaces, access and plan that make the suite feel like one system.
Product / 01
Project management and kanban
Plan projects, organise boards, move tasks through statuses and keep client work visible.

Time tracking and reporting
Record time against clients and projects, review reports and understand where team effort goes.
Product / 03
Documents and team knowledge
Create structured documents, connect resources and keep shared knowledge close to the work.
Product / 04
Your AI teammate hub
Shelly joins the suite as a teammate: crews take on work, follow skills, run tools and report back with your approval.
What every app shares
ShellStack gives every product the same organisation context, so your team does not need to rebuild the essentials each time they adopt another app.
One ShellStack account signs people into the apps they are allowed to use.
Personal and team spaces keep clients, projects, time and app data in the right place.
Invite teammates, assign roles and decide who gets Tides, TurtleTime, Kraken or Shelly.
Shared context lets apps work together, including Tides task time powered by TurtleTime.
Manage plans, seats and subscription details once for the whole product suite.
New ShellStack products can join the same user, workspace and billing layer.
How it works
Choose the people, roles, product access and workspaces from a single organisation. ShellStack carries that context across the suite while each product protects the work it owns.
