For founders

Every decision you made, every client you met, every thing you figured out, kept.

You ran ten conversations this week and made twenty calls under pressure. The Tuesday call with Acme. The pricing thing you settled on Slack at 11pm. The hire you almost made. By Friday half of it is gone, and the half you remember is the half you wrote down somewhere you can't find.

You talk. Sero files.

You wrap a call and tell Sero what came up. Sero, the agent inside Mycel, drops the notes into /Customers/Acme/calls/, updates the deal status, and notes that they want SAML by Q3. Three weeks later when they email asking about timelines, you don't scramble. You ask, and the answer is already there with a link to the file.

You don't have to change how you work.

No new tool to learn, no kanban board to maintain, no Notion migration weekend. You keep running the calls you were going to run, having the Slack threads you were going to have. Mycel slots in next to the conversations you are already having and writes the trail you wish you had been writing all along.

Your vault is yours.

Markdown files, real folder tree, exportable as a zip whenever you want. If you outgrow Mycel, or we disappear, you keep the brain you built. There is no proprietary database to escape from.
