Gainful
Personalized Performance Nutrition
If you are part of Gainful (or you are a YC founder who looks at Gainful and thinks that is the kind of business I run), you probably do not have time for a six-month SEO agency contract. Seoable was built for that. Audit your site, queue 100 ready-to-publish posts, and run it all from your AI assistant.

Why founders like Gainful use Seoable
- Ship without an agency. Audit your site and queue 100 posts in one afternoon. No briefs to write, no calls to take.
- Drive it from Claude or Cursor. Seoable is MCP-first. Your assistant can run audits, queue posts, and pull reports without you opening a dashboard.
- Pay per piece, not per seat. Credits instead of monthly seats. Buy what you need, when you need it.
- SEO that includes AI engines. Our audits check what ChatGPT, Claude, Perplexity, Gemini, DeepSeek, and Grok already say about you, not just Google.
