How to raise your first round

Everything I'd tell a founder raising from angels or going for their first VC round, in the order you'll need it.

Sauna 2.0 is here: announcing the different surfaces

Sauna now works in Slack, WhatsApp, iMessage, Email and Superhuman. It answers your messages as you, on LinkedIn and Instagram too, and it messages you first. A manifesto for not working at your computer, with a sauna you can play.

Your agent wasn’t in the meeting

When people disagree about the plan, giving each of them an agent gives the disagreement somewhere new to go.

How I run Sauna on Sauna

I wanted a meeting bot. Then I wanted a different notetaker. Four small apps I built around the way I actually work.

Skills worth borrowing

The workflows behind our everyday work. Copy a skill, give it to your AI, and make it your own.

Make a video with Sauna and Higgsfield

Connect Higgsfield, paste in the skill, and tell Sauna what to make. Two finished films and the full prompts to get you started.

The coworker, not the chatbot

A chatbot waits for your next message. A coworker remembers the last one, knows your tools, and gets the thing done while you're somewhere else. That gap is the whole product.

Text is async. Voice isn't.

Thinking about what changes when you talk to an agent instead of typing at it.
