何が起こったのか
Profound, a New York-based startup founded in 2024, announced a $180 million Series D funding round on September 15, 2026, at a $1.8 billion valuation. The round was co-led by Sequoia Capital and Kleiner Perkins, with participation from existing investors Lightspeed Venture Partners and Khosla Ventures. This follows a $96 million Series C round less than seven months prior that valued the company at $1 billion. Profound provides software for Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO), helping marketers monitor and manage how their brands are represented in AI-generated search answers rather than traditional search engine results pages. The company reported that its revenue has tripled over the past six months and that it now serves more than 1,000 enterprise customers, though these figures are company-reported and not independently audited. The new capital will be used to expand the company's AI-powered marketing platform, which covers marketing research, content, and broader marketing workflows.
