Profound, a fast-growing software startup that builds marketing tools to help major brands secure visibility in artificial intelligence-driven search results, announced on Tuesday that it has successfully raised a massive $180 million Series D funding round. The latest capital injection values the two-year-old enterprise at an impressive $1.8 billion. This milestone arrives less than seven months after the company closed its $96 million Series C round, underscoring the explosive market demand for technologies that navigate the rapidly shifting landscape of online discovery.

The high-profile funding round was co-led by prominent venture capital heavyweights Sequoia and Kleiner Perkins. They were joined by a roster of existing backers who participated in earlier stages of the company’s growth, including Lightspeed Venture Partners, Khosla Ventures, and South Park Commons. The rapid cadence of these funding rounds highlights the urgency with which brands are attempting to adapt as consumer search behavior pivots away from traditional web browsers and toward conversational artificial intelligence platforms.

Launched just two years ago, Profound initially entered the market as an analytics platform designed to help companies measure their digital footprint. Since its inception, the startup has rapidly expanded its product suite to encompass comprehensive market research capabilities and automated marketing strategy creation. At its core, the software helps businesses decode how modern consumers discover brands through AI tools, providing vital insights into algorithmic recommendations and conversational search queries.

Profound operates squarely at the forefront of a burgeoning wave of enterprise startups specializing in generative engine optimization and answer engine optimization, commonly referred to in the tech industry as GEO and AEO, respectively. As consumers increasingly turn to large language models, AI assistants, and automated search interfaces for recommendations, traditional search engine optimization strategies have become insufficient. Companies are now racing to find innovative, programmatic ways to ensure their products, services, and brand narratives are accurately and favorably surfaced within complex AI systems that dictate modern consumer choices.

The market validation for Profound’s technology is clearly reflected in its financial trajectory and rapid customer acquisition. According to the company, its overall revenue has surged threefold over the past six months alone. Furthermore, the startup has scaled its enterprise client roster to more than 1,000 corporate customers. This elite list of users includes major household names and global brands such as Comcast, The Estée Lauder Companies, and retail giant Walmart, all of which rely on Profound to maintain their competitive edge in an AI-dominated digital ecosystem.

As enterprise budgets continue to shift away from legacy digital marketing channels and toward generative search optimization, startups like Profound are poised to play a defining role in shaping how commercial entities communicate with audiences worldwide. With a fortified balance sheet and a rapidly expanding client base, the company enters its next phase of growth equipped to scale its engineering, product development, and global go-to-market operations to meet the accelerating demands of the digital economy.
