Agents that grow with you

Every agent starts at Level 1 and earns more autonomy as trust builds. You decide the pace.

L1Assisted

Every action goes through you. This is where every agent starts.

Most tasks run on their own. High-risk actions still need a human.

Full autonomy with daily reporting. Earned, never default.

We replaced three contractors and part of an agency retainer with Marsin in week two. Our content output tripled and our cost-per-qualified-lead dropped 38% in the first quarter.

The Campaign Manager agent runs our Monday planning, QBR prep, and weekly ops review without us touching it. We got 6 hours a week back across the marketing team.

I ran a 12-person agency on coffee and chaos. Marsin became my chief of staff. Retainer quality is up, client churn is down 22%, and I finally sleep at night.

Frequently asked questions

What is Marsin?+
Marsin is an AI-powered marketing platform by INSIDEA. It deploys 10 specialized AI agents: Marsin (strategy lead), Content Creator, Analyst, Outreach Lead, Brand Guardian, SEO Specialist, AEO Specialist, Social Media Manager, Email Marketing Lead, and Campaign Manager. They work together to handle your entire marketing operation.
How is this different from ChatGPT or other AI tools?+
Marsin isn't a chatbot. It's a team of specialized agents that connect to your tools (CRM, email, Slack), learn your brand voice, and execute marketing work under your supervision. They collaborate with each other and grow more capable as you give them more trust.
How do I get started?+
Sign up, connect your existing tools, and deploy your AI team. Most users are up and running in under 10 minutes with their first campaign live within the first week.
Can I control how much autonomy agents have?+
Yes. Every agent starts at Level 1 (Assisted) where you approve every action. As an agent proves reliable, you can promote it up the maturity ladder, all the way to Level 4 (Self-Driving). Promotion is earned, not automatic, and you can always step back in.
What tools does Marsin integrate with?+
HubSpot, Gmail, Google Calendar, Slack, and more. We're constantly adding new integrations. If you use it for marketing, we probably connect to it.
Is my data secure?+
Yes. Every organization gets fully isolated data. Integration tokens are encrypted with AES-256-GCM. We don't access, share, or train on your data.
