Y CombinatorYour work doesn't have to stop, even when you do.
Sauna runs in the cloud around the clock — drafting messages in your voice, tracking what matters, filing tickets, delivering briefings. You don't have to be online for work to move forward.
And you don’t have to Sauna alone…
Individual, but connected — every Sauna can open the door to another. Ask a colleague's Sauna a question, pull their perspective, or tap into their knowledge directly, without interrupting them.

Questions, answered.
What is Sauna?
Sauna is an AI agent that learns how you and your team work, remembers everything that matters, and acts on your behalf. The more context it has — your emails, documents, Slack messages, files — the smarter it gets and the more it can do.
What tools and apps does Sauna connect to?
Sauna connects to over 3,000 tools and apps — Linear, GitHub, Notion, Gmail, Google Calendar, Jira, HubSpot, Stripe, and more. You can also add custom MCP connectors for tools not in the connections list.
Does Sauna keep working when I go offline?
Yes. Sauna runs in the cloud around the clock — drafting messages in your voice, tracking what matters, filing tickets, delivering briefings. You don't have to be online for work to move forward.
Where can I use Sauna?
Wherever you work: the web app, iOS, iMessage, Slack, or email. One agent, the same memory, on every surface.
Can my whole team use Sauna together?
Yes — Sauna is multiplayer. Teammates share a Sauna's context and memory, so it can coordinate work across the team instead of starting from scratch with each person.
Is my data secure?
Yes. Sauna is SOC 2 Type II compliant, and your data is never used to train models or shared with third parties. Your context is yours — private, encrypted, and only ever used to do work on your behalf. See how we protect your data →
