Bluefish has closed a $43 million Series B, co-led by Threshold Ventures and NEA, with participation from American Express Ventures, TIAA Ventures, Salesforce Ventures, Bloomberg Beta, Crane Venture Partners, Laconia, and Swift Ventures. The round was announced on April 14, 2026 and brings the company’s total funding to $68 million inside two years of operation.
Rapid Adoption Among the Fortune 500
The raise lands at a moment when brand visibility inside AI systems like ChatGPT, Google AI, Claude, Perplexity, and Amazon Rufus has moved from experimental to boardroom-level priority. Bluefishreports that roughly ten percent of the Fortune 500now run on its platform, with named customers including Adidas, American Express, Hearst, LVMH, and Ulta Beauty. The company says it processes millions of AI prompts and responses per day across major models.
Experienced Leadership and Investor Backing
Bluefish was founded in 2024 by a leadership team with deep martech exits. CEO Alex Sherman co-founded PromoteIQ, which Microsoft acquired in 2019. CTO Andrei Dunca co-founded LiveRail, acquired by Meta in 2014. COO Jing Feng held senior roles at both companies. That pedigree is a large part of why NEA’s Ann Bordetsky, who led thefirm’s original Series A, returned for the B. NEA partner Bordetsky wrote in August 2025 that thefirm’s conviction in the category began with its investment in Perplexity two years earlier.
The Rise of Agentic Marketing
Bluefish has adopted the term “Agentic Marketing Platform” to describe its category, arguing that enterprise brands need infrastructure purpose-built for a world where AI agents — not human users — increasingly mediate discovery, comparison, and purchase. The company estimates the total addressable market for agentic marketing at $500 billion.
Implications for PR and Communications
For public relations and communications leaders, the Bluefish round is a signal, not a niche fundraising story. Agentic marketing platforms are consuming terrain that historically belonged to SEO agencies, PR firms, and corporate communications teams. When Adidas or American Express decides that its AI visibility is a measurable KPI, the reporting line and the budget often sit outside the traditional comms function. The firms that will defend and grow their enterprise accounts through 2027 are the ones that show up fluent in this stack — who can explain thedifference between prompt-level visibility, citation sentiment, and agent traffic without reaching for a vendor deck. This is a theme EverythingPR hastracked across its coverage of the generative engine optimization category.
Future Expansion
Bluefish is headquartered in New York with additional offices in San Francisco and Berlin, and plans to use the new capital to expand product, engineering, and client-facing teams.
