About Zeffo

We’re bringing AI agents into the workforce.

Zeffo is building the workspace where people and AI agents get real work done together, and people make the decisions.

Why Zeffo

AI got good at answers. Work needs more than answers.

Ask an AI a question and you’ll get a good answer. Then the real work starts: someone still opens the spreadsheet, sends the emails, chases the reply, and checks again next week.

We started Zeffo to give teams that time back. Its agents do the work in the apps your team already uses, keep it going on a schedule, and bring people only the decisions that matter, with a receipt for everything they did.

Our thinking has changed since our first version. We used to talk about agents that run on their own. Today we build for something better: people and AI agents working side by side, where an agent earns more room as its work checks out.

Bring AI agentsinto your workforce.
What we’re building

One agent to start. A whole team when you’re ready.

Start with Zeffo Personal. Bring your team in with Zeffo Work.

  1. Agent Zeffo

    The agent you meet first. It plans the task, does it across your apps, and asks before anything that matters.

  2. Your own agents

    Agents with a role, instructions, tools, a model and permissions, built for the jobs your team repeats.

  3. Workflows and routines

    What you do often becomes a workflow that runs on a schedule and waits for a person when it should.

  4. Spaces

    The workspace where people and AI agents work toward one goal, with a budget, stop rules and one Inbox.

  5. Zeffo Prime

    The desktop app and the command-line app (CLI) for your terminal, on Windows, macOS and Linux, plus the chat apps your team already uses.

What we believe

Five things we won’t trade away.

  1. 01 / 05

    People and agents, side by side

    Agents do the busywork. People decide what goes out. Neither replaces the other.

  2. 02 / 05

    Room is earned, not taken

    An agent does only as much as you allow, task by task. Anything important waits for a person.

  3. 03 / 05

    Proof, not promises

    Every action is logged with a receipt. You can see what happened and why, and step in at any time.

  4. 04 / 05

    Work where work already happens

    In the apps your team already uses, on your computer, and from your chat apps.

  5. 05 / 05

    Honest about what isn’t ready

    We say what works today and what doesn’t yet, and we don’t show what we can’t do.

The team

A small team, building in the open with our first users.

We’re early, and we’d rather get this right than get it fast. We work closely with the people we invite, and what they tell us shapes what we build next.
