AI agents for SaaS companies

You build the product. Agents run the rest.

Support tickets, bug reports, failed payments, trial follow-ups and the Monday metrics, handled every day by agents that know every account. Your team stays on the roadmap.

Where a SaaS team's week really goes.

Not into the roadmap. Into tickets, payment failures, follow-ups and the spreadsheet everyone asks for on Monday. Switch the week to see who does it with Brainstack.

Customers hear from you, on your terms.

Agents handle the routine. Money, plans, mass emails and code changes always wait for a person.

Your rules

Refunds and creditsAlways asks
Email every userAlways asks
Merge or deploy codeNever
  • Refunds, credits and plan changes

    The agent brings the account history and a recommendation. The decision is yours.

  • Anything sent to your whole user base

    Release emails, pricing news and incident updates wait for a yes.

  • Issues, not code changes

    Agents read repos and file issues. Merging and deploying stay with your engineers.

  • Each person sees only their accounts

    Permissions follow your team: an agent never shows someone data they couldn't open themselves.

  • Your own server in the EU

    Your brain runs on its own machine in the US or Europe, with encrypted backups every 6 hours.

SaaS questions, answered.

Can support answer from our docs and help center?

Yes. Connect your docs (Notion, Drive, your help center) and support conversations, and the agent answers from them, passing anything that looks like a bug to triage.

Do agents touch our code?

They read repositories, issues and pull requests to file better issues and write release notes. Merging and deploying stay with your engineers.

Stripe or Chargebee?

Both connect. Agents read subscriptions, invoices and payments to catch failed charges and build your weekly numbers.

Can our engineers use the brain from Claude, ChatGPT or Cursor?

Yes, in beta. Each person connects their own AI to the company brain, and the connection never sees more than that person can.

Where is our data kept?

Your company brain runs on its own server in the US or Europe, with encrypted backups every 6 hours. The AI model you choose processes each request under its provider's terms.

Which plan fits a SaaS team?

Up to 3 people starts on Starter ($99/month). Up to 10 people fits Growth ($499/month), up to 30 people Scale ($999/month). Larger teams talk to us about Custom. Your AI plan is paid directly to the provider.

Your next thousand users won't need another hire.
