Profound invests in Kleiner Perkins
Funding Provisional 90% confidence first seen
Profound announced a $180 million Series D round at a $1.8 billion valuation, co-led by Sequoia Capital and Kleiner Perkins. The reported investment is intended to expand Profound’s applied-AI and marketing platform work (including improving how brands are surfaced and cited in AI search/answering systems and building measurement and model customization capabilities). This matters because it further backs Kleiner Perkins’ push into the fast-growing AEO/GEO “answer engine optimization” marketing software category.

Deal terms as reported in the coverage below.
Decision brief
- What changed
- Profound raised a $180 million Series D at a $1.8 billion valuation, with Sequoia Capital and Kleiner Perkins co-leading the round. According to the coverage, Profound will use the funding to open an applied-AI research operation in San Francisco and expand its AI Marketer product into paid AI Search campaign management through Ads Studio.
- Why it matters
- This financing materially increases resources behind a company building software for brand visibility and campaign management in AI-driven search and answer interfaces, an emerging marketing workflow adjacent to traditional search marketing. For decision-makers, the round is a market signal that major investors see commercial value in tools that help brands manage presence, measurement, and spending in AI answer environments. It also raises the likelihood of faster product development and category competition in AI-search marketing software.
- Evidence
- The summary is supported by a single cited report from Tech Funding News AI, which states that Profound raised $180 million at a $1.8 billion valuation, co-led by Sequoia Capital and Kleiner Perkins, and describes the intended uses of funds. Because the provided coverage consists of one outlet only, the funding details and strategic implications are not independently corroborated here.
- What remains uncertain
- The coverage does not verify customer traction, revenue, product adoption, or whether Profound’s expansion into paid AI Search campaign management will translate into measurable enterprise demand. It also does not establish how differentiated Profound is versus other AEO/GEO or broader marketing-tech vendors, so competitive impact should be treated as an assumption rather than a confirmed outcome.
- Monitor next
- Watch for concrete launch and adoption signals for Ads Studio and the new applied-AI research operation, especially announced customers, partnerships, or usage metrics tied to AI-search campaign management.
