AI-Native SaaS

BusinessBrain

A multi-tenant platform that acts as an AI employee — learning a business's operations and handling customer conversations and tasks across WhatsApp, Instagram, Facebook and calendars.

Client  Cortex Development (product)

Context

Our own flagship product, and the reference build for how we approach AI-native SaaS.

The problem

Small businesses lose revenue to slow, manual customer handling — inquiries, quotes, bookings and follow-ups spread across channels with no system behind them.

What we built

A dynamic "Business Brain" learns each tenant's services, products, policies and workflows. The AI then handles customer conversations and executes tasks — lead capture, quotes, appointments, orders — across WhatsApp, Instagram, Facebook and Google Calendar. A Business Autopilot analyses activity to surface opportunities and recommended actions, with human approval for sensitive operations.

Outcome

Multi-tenant from day one, event-driven, with real-time dashboards. Now the template we use for client AI-SaaS builds.
