Our partner Bolster Ai, the multi-channel phishing protection provider, has secured $14 million in a Series B funding round, bringing the company’s total funding to over $40 million.
The round was led by Microsoft’s venture fund M12, with participation from Cervin Ventures, Cheyenne Ventures, Crosslink Capital, Liberty Global Ventures, Thomvest Ventures, and Transform Capital.
Founded in 2019 in Santa Clara, California, Bolster prevents phishing and impersonation attacks across mobile applications, messaging tools, websites, and social media platforms.
Bolster uses AI and ML to train models on URLs, domains, emails, and natural language texts, enabling large-scale detection of phishing and scams across multiple channels. The company currently serves over 120 customers, including many well-known brands.
The new funding will be used to accelerate Bolster’s go-to-market initiatives, focusing on executive monitoring, BEC detection and prevention, and threat-hunting automation. Additionally, Bolster will invest in training and marketing efforts related to these key areas.
