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.

The AI productivity suite with agents, email, and docs that work wherever you do
Superhuman Go brings AI agents into the tools and tabs you already use, with inline suggestions and context-aware chat.
Auto drafts, split inbox, auto labels, and auto archive keep your inbox manageable with minimal manual filing.
Collaborative documents that hold text, tables, data, and workflows in one connected surface.
Describe what you need in chat or use a visual builder, then share agents with teammates or a company directory.
