# Start a team

Sign in, name your team, and follow the start page to connect your AI tools, your numbers and your people.

## Signing in

Sign in with a link sent to your email address. If you would rather use a password, set one under Account, then Security, and sign in with your email and password from then on. The link still works if you lose it. Every person on a team signs in as themselves.

## Naming the team

Name your team and choose the team's address. The person who starts a team is the team's owner and first admin. Every new team starts on the Free plan. [Plans and background reading](https://zerowidth.ai/docs/hosted/plans)

## The start page

Each team opens on a start page with four first steps:

1. **Connect your AI tools.** Every tool uses your team's one MCP address. [How connecting works](https://zerowidth.ai/docs/connect/how-connecting-works)
2. **Connect your numbers.** ZeroWidth checks each decision against the numbers it was meant to move. [Send numbers to ZeroWidth](https://zerowidth.ai/docs/hosted/send-numbers)
3. **Bring in past chats.** Exports from Claude, ChatGPT, Slack and other tools fill the record with the decisions your team has already made. [Past chats](https://zerowidth.ai/docs/connect/past-chats)
4. **Invite your team.** An admin invites people by email from the Team page. [Members and sign-in](https://zerowidth.ai/docs/hosted/members)
