What you get with Simurg.
A team, not one assistant.
Sales, support, finance and marketing are separate agents. Each has its own job and hands work to the next, and you can follow every handoff.
It moves when your business moves.
A routine starts the moment a customer emails, a table changes or a webhook arrives. Nothing waits for the next check.
Your records have a home.
Leads, invoices, tickets and orders live in tables your agents keep up to date, so there is no separate database to pay for.
Each agent gets only what it needs.
Its own apps, tools, skills and knowledge folders. The agent writing your posts never has to see your invoices.
The right model for each job.
On Growth and Scale, run each agent on the model that suits it, from several makers, with your own key.
Set up in one sentence.
Tell ARCHITECT what your business does. It plans the team, the tables and the routines, and you approve the plan.
