RankScience was founded in Y Combinator's W17 batch with a mission to bring data-driven SEO to fast-growing startups. Today, RankScience is a pioneer of SEO and AI search, specializing in Generative Engine Optimization (GEO), Large Language Model Optimization (LLMO), and Answer Engine Optimization (AEO). RankScience helps companies capture visibility across Google, Google AI Overviews, ChatGPT, Claude, Gemini, and Perplexity.
RankScience's CEO brings over 15 years of digital marketing expertise, leading a team of SEO specialists and AI visibility experts. Having developed strategies at scale with Fortune 100 companies like AT&T and Thomson Reuters FindLaw before focusing exclusively on startup growth, this unique combination of enterprise and local search experience allows RankScience to deliver sophisticated SEO and AI visibility strategies with the agility and cost-effectiveness that high-growth companies need.


Since 2017, RankScience has helped hundreds of startups, including Zapier, Calm, and Rippling, master foundational SEO (technical optimization, content strategy, and authority building) while developing a sophisticated AI Visibility framework. RankScience practices what it preaches: RankScience.com consistently achieves LLM traffic in the double digits as a percentage of Google organic traffic, with conversion rates 4-5x higher than traditional Google traffic. RankScience has supported companies from seed stage through Series C, turning both traditional search and AI platform visibility into true growth engines.
