# Plurank

> The Data Layer for AI Search — measure and predict brand citation in AI answers across 7 AI search platforms and 12 countries. Korean B2B SaaS company; founded 2025; Seed Round 2026.

Plurank ("Plu" multi + "rank") is the data infrastructure for the GEO (Generative Engine Optimization) era. SEO measured Google search ranking; Plurank measures who AI search engines cite. We help marketing agencies, in-house brand teams, and developers see where their brand appears in AI answers — and predict citation probability before they publish.

What Semrush did for SEO, Plurank does for GEO.

### Pluora prediction model
A multi-signal AI model trained on 30M+ published-to-cited data records, capturing 12 countries × 7 AI search platforms weekly via real browser sessions with residential ISP IPs.
