An AI operating system that runs sales intake, research, proposals, and invoicing in one accountable system
Brings sales intake, research, proposals, invoicing, and related workflows into a single accountable system instead of scattered tools.
Captures and processes inbound sales requests so new demand is logged, qualified, and routed without manual re-entry.
Supports the research stage and the drafting of proposals that follow from it, keeping context in one place.
Extends the same system into invoicing and connected operational workflows so the revenue path stays continuous.
No-code AI agents that resolve support and sales conversations
Define personality, guidelines, system prompt and model, then test the agent before going live.
Import PDFs, docs and URLs that auto-refresh so answers stay grounded in current documentation.
Connect Stripe, Shopify, Zendesk and your own APIs so the agent can look up orders, issue refunds and create tickets.
Launch the same agent on your website widget, WhatsApp, Messenger, Instagram, Discord, Telegram and helpdesks.
