Dagny vs Sauna.

Sauna is one of the closest things to Dagny out there, and a very good one: a proactive teammate with shared memory, on the web, iMessage, Slack, and email. The difference is who it is built for and what it covers. Sauna is tuned for knowledge-work teams; Dagny is built for owner-run businesses, and she runs your public website and search presence as well.

AI teammate

What Sauna does well

A lot to admire: its own computer in the cloud, more than 3,000 integrations plus custom MCP, memory the team can share or keep private, a choice of models, and autonomy you can dial from suggestions to fully on its own. It answers on the web, iOS, iMessage, Slack, email, and inside Superhuman. If your team runs on docs, tickets, and pipelines, it is excellent.

Where Dagny is different

Look at the channels Sauna shows itself working in: growth, sales, engineering, hiring, founders. That is a knowledge-work team, and Sauna serves it well. The clinic, the contractor, and the shop have a different list: the customer on WhatsApp, the follow-up nobody wrote down, the website that still lists last year's prices. Dagny answers on WhatsApp as well as iMessage, Slack, and email, drafts outbound for your yes by default, and builds, hosts, and maintains your public website and your presence in search and AI answers. Sauna builds routines and apps for your team; your public face is not its job.
