SEO was a black box — no one had tools to understand why sites ranked or how to improve systematically.
Founded 2004 as SEOmoz blog, grew into a SaaS platform. Raised $29M in funding. Rand left in 2018 to start SparkToro.
Helped define the SEO tools category and created the Domain Authority metric used across the industry.
Democratize access to SEO data so every business can compete in search, not just those with big budgets.
