Doppel Secures $35M in Series B Funding, Accelerating AI-Driven Social Engineering Defense

May 3, 2025 By admin Leave a Comment

Doppel, an innovative platform dedicated to defending against sophisticated social engineering attacks through advanced artificial intelligence, has successfully closed a $35 million Series B funding round, bringing its total capital raised to $54.4 million. The latest investment values the rapidly expanding company at $205 million, underscoring investor confidence and market validation. Leading the round is prominent venture capital firm Bessemer Venture Partners, joined by new investors 9Yards Capital and Sozo Ventures, along with ongoing support from existing stakeholders including a16z, South Park Commons, Strategic Cyber Ventures, Script Capital, and Sabrina Hahn.

Driven by exponential demand from organizations seeking proactive cybersecurity solutions, Doppel’s innovative technology offers comprehensive protection against social engineering threats targeting executives, brands, and employees. The company’s flagship Doppel Vision platform merges sophisticated AI-powered large language models with human expertise, enabling effective identification and neutralization of emerging threats. Through mapping attacker infrastructures and performing proactive takedowns across diverse digital environments—from domains and email systems to social media channels and mobile apps—Doppel’s solution has quickly proven essential for enterprise risk management.

The Series B financing arrives on the heels of impressive growth. Since its Series A funding round in January 2024, Doppel experienced a remarkable 400% increase in enterprise customer adoption, a 90% expansion in total customer base, and achieved triple-digit growth in annual recurring revenue (ARR). Its business model continues to scale sustainably, boasting a compound annual growth rate (CAGR) of 230% since 2022. Much of this growth is attributed to Doppel’s ability to refine and operationalize AI tools developed in collaboration with OpenAI, creating an industry-first cybersecurity AI agent capable of independently detecting and neutralizing complex social engineering campaigns.

Operational enhancements resulting from this cutting-edge integration have notably doubled the efficiency of Doppel’s internal security teams, setting the stage for continued productivity improvements through upcoming product releases. The firm’s strategic partner, Secure Consult, underscores Doppel’s significant impact in redefining executive protection strategies. Secure Consult’s CEO, David M. Gordon, emphasized the value of their alliance, highlighting Doppel’s role in delivering proactive, real-time security solutions that address threats comprehensively, from initial detection through final resolution.

Bessemer Venture Partners’ Elliott Robinson further affirmed the strategic rationale behind their investment, noting Doppel’s rapid ascension as a market leader due to its innovative approach in thwarting highly personalized cyber threats that increasingly compromise organizational security. Doppel CEO Kevin Tian expressed enthusiasm for the partnership with Bessemer, acknowledging the firm’s extensive experience in supporting transformative businesses. Tian affirmed the new funding would be strategically allocated to enhance Doppel’s core technological capabilities, address burgeoning market demand, and further cement its position as the definitive leader in social engineering defense.
