Profound, a developer of marketing software for AI search optimization, secured $180 million in a Series D funding round. The investment brings the company valuation to $1.8 billion, just seven months after its previous $96 million Series C round.

The financing round was led by Sequoia and Kleiner Perkins. Existing investors, such as Lightspeed Venture Partners, Khosla Ventures, and South Park Commons, also contributed to the deal. The company plans to utilize the capital to support its growth in the AEO and GEO sectors.

Founded two years ago, the startup initially focused on analytics before expanding into research and marketing strategy tools. Its platform assists businesses in understanding how consumers discover brands through AI-powered search systems.

The company reported a threefold increase in revenue over the last six months. Its client base currently exceeds 1,000 enterprise customers, including major corporations such as Walmart, Comcast, and The Estée Lauder Companies.
