Bolster Raises $14 Million for AI-Powered Phishing Protection

Bolster has raised $14 million in Series B funding for technology integrations for its AI-powered phishing protection platform.

Multi-channel phishing protection provider Bolster has raised $14 million in a Series B funding round that brings the total raised by the company to over $40 million.

The new investment round was led by Microsoft’s venture fund M12, with additional funding from Cervin Ventures, Cheyenne Ventures, Crosslink Capital, Liberty Global Ventures, Thomvest Ventures, and Transform Capital.

Founded in 2019, the Santa Clara, California-based company prevents phishing and impersonation attacks across mobile applications, messaging tools, websites, and social media platforms.

Bolster leverages AI and ML to train models on URLs, domains, emails, and natural language texts, for multi-channel phish and scam detection at scale. The company says it currently serves over 120 customers, including well-known brands.

The company will use the new funding to accelerate its go-to-market initiative, with a focus on executive monitoring, BEC detection and prevention, and threat-hunting automation. Bolster will also invest in training and marketing initiatives centered around these key areas.

“Bolster is committed to leading the industry in leveraging generative AI for real-time detection and response to phishing and impersonation attacks. This issue impacts nearly all businesses today,” Bolster co-founder and CTO Shashi Prakash said.
