❓ FAQ

What's the single most valuable AI use case for a solo founder?

Customer communication and content creation. A solo founder using Claude for emails, landing pages, and support responses operates with the output leverage of a small team.

Can AI help with fundraising?

Yes — for drafting investor materials, researching investors, and preparing for Q&A. But investor relationships and the pitch itself still require human founders. Use AI to prepare faster, not to replace the conversation.
