From idea to execution with an AI co-founder
Begin with who you are — how you think and work, what you optimise for and your constraints — so ideas start from fit rather than trends.
Test whether people actually have the problem and are willing to pay, with idea scoring, market demand checks and objective comparisons of alternatives.
Turn what you learned into a coherent plan with a seven-section business plan builder, go-to-market strategy and financial projections.
An AI co-founder that maintains context over time, from identity and idea context to full memory, plus decision checkpoints and ongoing nudges.

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.
