EULER raises $4.3 million seed to scale agentic partner management

EULER, the San Diego-based agentic partner relationship management platform, raised $4.3 million in seed funding led by Channel Equity Partners. The company says the capital will help it expand hiring, speed product development and push partner programs deeper into B2B software revenue strategy.

Why it matters: - Partner programs now drive a meaningful share of revenue at many B2B software companies, but many teams still rely on spreadsheets, email and underused portals. - EULER is pitching an AI-native alternative that automates partner onboarding, training, deal registration, attribution and support. - The funding gives EULER fresh capital after bootstrapping to profitability, signaling investor confidence in partner revenue infrastructure.

What happened: - EULER raised $4.3 million in seed funding in its first institutional round. - Channel Equity Partners led the round. - EULER said the money will expand the team, accelerate product velocity and scale go-to-market. - The company is based in San Diego. - The announcement came on Aug. 24, 2026.

The details: - EULER said it has been profitable and bootstrapped since launch. - The company said annual recurring revenue grew 600% in 2025. - EULER said revenue doubled in the first half of 2026. - Founder and CEO Greg Portnoy said the company raised because demand accelerated, not because it needed the money. - Portnoy said partnerships have moved from a side project to a core revenue strategy for many companies. - Andrew Albert, managing partner at Channel Equity Partners, said enterprise technology companies have been overly reliant on direct sales and are shifting more resources into channel sales. - Albert said EULER is an AI-native PRM built for enterprise teams that want to scale partner revenue. - EULER said partner programs drive 30% to 50% of revenue at many B2B software companies. - EULER said its platform replaces manual partner operations with agents that handle onboarding, training, enablement, deal registration, attribution and support. - In Q2, EULER launched an MCP integration. - EULER became the first PRM available in Anthropic's Connector Marketplace. - The integration lets partners access and manage programs directly from AI tools they already use. - Since June, EULER's AI agents have answered more than 50,000 questions for 7,700 partners. - EULER estimated those agents saved users more than 31,000 hours during that period. - EULER said it powers more than 100,000 partnerships for customers including Gong, BambooHR, Zip and BigCommerce. - The company also counts category-defining customers in AI, aerospace and developer tools. - EULER said customer results include 7x growth in partner-attributed revenue, 20x faster partner payouts and 50 hours of monthly operational capacity recovered. - BambooHR's Lilly Criscione said EULER is genuinely AI-native and built around agentic experiences rather than a chatbot layered onto older software. - Jay McBain, chief analyst for channels, partnerships and ecosystems at Omdia, said 44% of partners are already deploying software agents and that could rise to 64% within 18 months. - McBain said partners deliver two-thirds of revenue in a $6.2 trillion IT market and surround 96% of deals. - EULER said it has tripled its team over the past year. - The company plans to double headcount again within six months across engineering, product, sales, customer success and marketing.

Between the lines: - The round reflects growing investor interest in infrastructure tied to partner-led growth, not just direct sales automation. - EULER is framing agentic AI as the next step after traditional PRM software, with fewer manual workflows and more in-product partner engagement. - The Anthropic Marketplace placement suggests EULER is trying to meet users inside the AI tools they already use, not force them into a separate portal.

What's next: - EULER plans to use the new funding to hire more aggressively and ship product faster. - The company is also expected to keep expanding its go-to-market motion as partner programs take on a bigger role in B2B revenue strategy. - EULER says it will continue building infrastructure for measurable and predictable partner revenue.
