Listen to this articleBluefish has raised $43 million in Series B funding, bringing its total capital to $68 million since launching in 2024. The round will fuel expansion of its Agentic Marketing Platform, which helps Fortune 500 brands monitor, optimize, and measure their presence across major AI assistants.
Bluefish has closed a $43 million Series B funding round, co-led by Threshold Ventures and NEA. Participating investors include Amex Ventures, TIAA Ventures, and Salesforce Ventures, with continued participation from Bloomberg Beta and existing backers Crane Venture Partners, Laconia, and Swift Ventures. This round brings Bluefish’s total funding to $68 million in just two years since its 2024 launch.
The Series B follows the company’s $20 million Series A in August 2025, which was led by NEA and Salesforce Ventures with participation from Crane Venture Partners, Swift Ventures, and Bloomberg Beta and brought total funding to $24 million at the time. The rapid progression from seed to Series B in under two years highlights exceptional momentum in the enterprise AI marketing sector.
Bluefish operates as the Agentic Marketing Platform (AMP) purpose built for Fortune 500 brands. It delivers an end to end suite that combines AI monitoring, activation, and measurement to give marketing teams visibility and influence over how AI systems portray their products and brands. The platform processes millions of AI prompts and responses daily across major models including ChatGPT, Google AI, Claude, Perplexity, and Amazon Rufus, surfaces that now reach over one billion monthly active users. It supports integrated workflows for Search, Content, PR/Comms, Commerce, and Paid Media teams, enabling brands to analyze sources and narratives driving LLM outputs, run optimization campaigns, and directly attribute results to lifts in visibility, favorability, and revenue.
Adoption has been swift. Bluefish serves approximately 10% of the Fortune 500 with hundreds of accounts spanning more than 12 verticals, including financial services, pharmaceuticals, beauty, luxury, and consumer packaged goods. Notable customers include Adidas, American Express, Hearst, LVMH, and Ulta Beauty. Prior to the Series A, the company reported 10x revenue growth in six months and double to triple digit performance gains for brands within months of implementation. The platform’s enterprise grade design, emphasizing customized methodologies, transparency into prompts and sources, and durable optimization rather than short term algorithmic gaming, has positioned it as the default choice for sophisticated marketers seeking defensible AI presence.
The $43 million will primarily accelerate platform rollout across additional Fortune 500 brands and marketers while supporting hiring expansion, international growth, and continued product investment. This timing aligns with the broader shift toward agent driven commerce, where consumers increasingly discover and evaluate products through AI assistants rather than traditional search or social channels. Bluefish explicitly frames AI as the next major marketing channel, comparable to the rise of search, social, or mobile, requiring the same enterprise stack sophistication that brands already demand elsewhere. By focusing exclusively on enterprise needs, the company has carved a leadership position in the estimated $500 billion Agentic Marketing opportunity.
Investor conviction is evident in the syndicate’s composition and commentary. NEA, returning as co-lead after anchoring the Series A, cited Bluefish’s fast scaling, triple digit performance gains, and convergence of market inevitability, customer demand, defensible platform, and proven team. Threshold Ventures highlighted the platform’s unique combination of depth, scale, and measurable results that no other solution currently matches. Amex Ventures emphasized the platform’s alignment with enterprise marketing requirements and its role in reshaping customer brand engagement. These statements reinforce Bluefish’s differentiation: it does not chase transient LLM hacks but instead helps brands earn consistent preference through structured intelligence and activation at scale.

Founded by Alex Sherman (CEO), Jing Feng (COO), and Andrei Dunca (CTO), a team with prior experience founding, scaling, and exiting marketing platforms acquired by Microsoft and Meta, the company has assembled an executive bench blending enterprise marketers and AI engineers from Microsoft, The Trade Desk, AppNexus, Publicis, and major CPG brands. This pedigree has enabled rapid product market fit in a category where technical depth and marketing sophistication must coexist.
The Series B validates Bluefish’s thesis that agentic marketing is moving from experimental to mission critical for large enterprises. The funding provides the resources to solidify category leadership, expand geographic and vertical reach, and deepen platform capabilities precisely as AI surfaces become primary discovery channels. With $68 million in total capital, a concentrated Fortune 500 customer base already delivering outsized results, and a clear roadmap for the agent driven era, Bluefish is positioned to capture significant share of the emerging $500 billion market while setting the standard for enterprise grade AI marketing infrastructure.
