Lapis

Lapis (Lapis Labs, YC F25) is an AI marketing platform founded by Varunram and Sai that helps businesses capture visibility on AI search engines including ChatGPT, Claude, Perplexity, Gemini, and Grok. Unlike traditional SEO which targets Google's blue-link results, Lapis focuses on the growing shift in information discovery toward AI-generated answers. The platform works by analyzing over 650 million tokens per day to understand AI model responses, constructing detailed graphs of websites referenced for given queries, and dynamically modifying website content in real time to maximize AI search visibility. Key capabilities include real-time landing page personalization based on the AI query context, fully automated technical SEO (meta tags, title tags, OpenGraph, sitemaps), and prompt analytics that surface untapped market verticals. Lapis also manages link placement on high-authority domains cited by AI models. The company supports over 100 fast-growing startups including Warp, Reducto, and Greptile, and offers a free tier to get started.
