Loved by teams
Teams that stopped losing track of work.
From two-person startups to company-wide rollouts — here's what changes when everything lands in one place.
“STACK replaced six open tabs and our morning standup. I open it once and I already know exactly what matters today.”
Sarah Chen
Design Lead, Acme
“Decisions used to get lost in chat. Now every meeting turns into a summary, action items and assigned tasks automatically.”
Marcus Webb
PM, Globex
“The daily AI brief became our executive routine. I get the company-wide picture in sixty seconds instead of sixty emails.”
Priya Nair
COO, Initech
“Automations quietly turn every meeting into tasks. Nobody on the team has to remember to do it anymore.”
Alex Rivera
Engineering Lead, Umbrella
“Universal search actually works — I find the right file, thread, or task in one search bar instead of five apps.”
Jordan Lee
Freelance Designer
“Onboarding new hires used to take a week of tribal knowledge. Now STACK just shows them what's happening.”
Morgan Blake
Head of Ops, Hooli
The problem
Your work is everywhere.
Email here. A Slack message there. A calendar invite, a task, a file, a notification — scattered across a dozen tabs you have to hold in your head all day.
Q4 proposal needs sign-off
“Can you review this today?”

From scattered to connected.
STACK pulls every one of those moments into a single, intelligent view — so you always know what needs you next.
The product
One workspace for every kind of work.
Tasks, projects, conversations, and files — organized the same way, searchable the same way, understood by the same AI.
How it works
Your apps do the work. STACK connects it.
STACK isn't another inbox or another task list. It sits above the tools you already use and makes sense of what's happening across all of them.
Everywhere you work
Every surface, exactly where you expect it.
STACK stays in sync across desktop, web, and mobile — pick up a task on your phone, finish it at your desk.
STACK AI
Ask anything about your work.
STACK AI combines your tasks, files, messages, and meetings to answer in seconds — and always shows where the answer came from.
Customer Onboarding Revamp is behind schedule — no updates in 6 days and 4 tasks are overdue.
Automations
Let STACK handle the busywork.
Build visual workflows that trigger on emails, messages, meetings, or deadlines — no code required.
