Pinnacle
API & SDK for RCS (the next-generation of texting)
If you are part of Pinnacle (or you are a YC founder who looks at Pinnacle 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.
About Pinnacle
Pinnacle is an API for RCS, the new standard for SMS for app-like text messages. For example, developers can create messages that show products that can be purchased with one tap natively on iOS and Android. If you're currently using SMS from Twilio, etc, and you don't want to leave money on the table, get in touch with us - [email protected] with subject "YCBIO". If you're a YC company, we'll get you a free founders mode™️ hat, 1000 free msgs/mo + 24/7 real founder mode™️ support when you switch to us.

Founders
Why founders like Pinnacle 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.
