❯ Profound Raises $180M Series D, Reaching a $1.8B Valuation Within Seven Months

Rapid returnAI marketing platform Profound raised a $180 million Series D at a $1.8 billion valuation, co-led by Sequoia Capital and Kleiner Perkins. Lightspeed, Khosla Ventures, Saga Ventures, Evantic and South Park Commons participated. The platform tracks how brands appear in ChatGPT, Gemini, Perplexity and other answer engines, then lets agents research, write, refresh content and run advertising from those insights.

Seven monthsThe round comes less than seven months after a $96 million Series C in February 2026 at a $1 billion valuation, increasing the price by 80%. Buyers no longer discover brands only through lists of web links; answer engines synthesize product pages, documentation, reviews and media. Profound has consequently expanded from AI-search visibility analytics into AI Marketer, which performs research, content, advertising and reporting work.

Brand dataProfound says it serves more than 1,000 enterprise brands, including over one-third of the Fortune 100 and 16% of the Fortune 500. Customers include Comcast, Estée Lauder, Walmart, Zoom, ServiceNow, Ramp, Cursor and Figma. The platform is built on more than 2 billion real user prompts; Context Manager unifies company knowledge, while Ads Studio connects OpenAI, Google and Meta advertising. Funding will also expand its applied-AI labs in New York and San Francisco.

A new search budgetMarketing spend is shifting from ranking web pages to winning brand selection inside answer engines. Profound combines prompt data, brand context and execution tools, allowing it to reach beyond analytics subscriptions into content and media budgets. Yet attribution remains harder than tracking clicks. It must connect model mentions to sales or acquisition cost, or the pace of financing will pull category-education expenses forward.

▪ SIGNALAs consumers ask models before visiting websites, brands will redirect part of search optimization budgets into answer-engine monitoring and execution.
