Enable your team with all the best models, without committing to a single vendor.
Trusted by leading organizations
What independence looks like
Spend over 90% less on AI
Never get trapped in a single ecosystem. Switch models freely and pay only for actual usage.

Choose where your organization works. Stay on a desktop app your teams already love or any other one.
An AI bill you can predict
Spend you can see
Cost by team, model and task, visible as it happens rather than on the invoice.
Intelligent model routing
Frontier where it matters, the most cost-efficient everywhere else.
Eval mode
Run the same task on different models before deciding which one to use.

Legal review stays on a frontier model. A wrong redline costs more than the tokens.

A mid-tier model clears it. Prose quality matters here, and frontier would cost more for no visible gain.

Harriet Draft, not sent
Hi Priya, you're set to carry 11 days into next year and our policy caps it at 5. Days above 5 lapse on 31 December. Could you book the rest before then, or talk to Dana if that's not workable?

Draft To Hannah Croft, Halden Capital. Subject Ops at Halden after the Team plan
Hi Hannah, Halden crossed 300 people this year, which is usually when a Team plan starts to creak: seat caps, overage requests, an Enterprise quote nobody budgeted for. Would a 20-minute look at how other teams your size handled it be useful? Maya

Xero, invoices due in 14 days → Zendesk, one ticket each, assigned to owner → #finance, summary September product update: three things, one page
Blog draft, opening
August was our best month for inbound yet, 41 MQLs and a pipeline that finally reflects the work Ops has put into onboarding. So September's update is about the three things customers asked for most: shared skills you can hand to a new hire, connectors you can scope by team, and a spend view your CFO will actually open.
Post 1: Shared skills
Your best analyst's checklist, now something the whole team can run. Here's how three customers used it in August.
Post 2: Scoped connectors
Finance sees Xero. Sales sees Salesforce. Nobody sees everything. Connector scoping by team is live.
Post 3: Spend view
One screen, every team's AI spend, projected before the invoice lands. Built for the person who signs it.
Security-first
Every connector and skill reviewed
Scanned and banded before a team can use them.
Every action on the record
Prompts, connectors and tool calls, audited as they happen.
Compliant and hosted in the EU
Audited, certified, and never trained on.
