API
Developer API

Headless ready. Send events, capture users, and trigger workflows via REST API.

Platform Architecture
Why It Works

One co-founder. Every tool connected.

Most founders fail because their strategy lives in a doc, their leads in a spreadsheet, and their emails in another tool. Your AI co-founder connects everything — so every decision is grounded in your strategy, and every action moves you toward your first customer.

Seamless Data Sync

When a user chats with your AI bot (Builder), they are automatically tagged in your CRM (Marketing). No Zapier or manual exports needed.

Unified Analytics

See the full customer journey: from the first cold email open, to the website visit, to the final conversion. All in one dashboard.
