Herd Security Raises $3M for AI Security Training Platform

Key Takeaways

1. San Francisco-based Herd Security has closed a $3 million funding round led by Aspiron Ventures, with participation from ForwardSlash VC, Forum Ventures, Rightside Capital, Team Ignite, and YPO
2. Founded in 2025 by CEO Brandon Min, a former Duo Security alum, the platform replaces static, annual compliance training with AI-generated micro-lessons delivered directly inside Slack, Microsoft Teams, and LMS tools
3. The company will deploy capital across three priorities: expanding training categories into HR and AI, optimizing AI-powered video generation, and scaling its partnership ecosystem
4. Herd Security operates in a security awareness training market estimated at $6.74 billion in 2026, projected to reach $14.66 billion by 2031 at a 16.82% CAGR

Quick Recap

Herd Security, a San Francisco-based agentic AI startup, has officially announced a $3 million seed funding round led by Aspiron Ventures. The announcement was first surfaced via The SaaS News on X and has since been confirmed by SecurityWeek and SiliconAngle. Founded just in 2025 by CEO Brandon Min, Herd has built a platform that automates continuous security awareness training and phishing simulation so organizations can move beyond the industry’s broken model of once-a-year compliance videos.

A Platform Built for the Era of Daily Threats

Herd Security’s core product parses an organization’s imported security policies, compliance frameworks, and threat data, then automatically generates short, contextual micro-training modules and phishing simulations tailored to each employee’s role and risk profile. Training is pushed through tools employees already use, including Slack and Microsoft Teams, in formats ranging from text and images to video and conversational AI, removing the friction of forcing users to log into a separate learning portal.

The platform is described by the company as the first to “fully automate the human risk lifecycle,” covering simulation creation, training delivery, engagement tracking, and compliance reporting with zero manual overhead. CEO Brandon Min, a former engineer at Duo Security and founder of earlier cybersecurity ventures, has positioned Herd around a philosophy of empathy-led security, arguing that organizations have historically vilified employees for clicking on phishing links rather than equipping them with genuinely relevant, real-time training.

The new capital will specifically fund three growth pillars: expanding training content categories into HR and AI awareness, enhancing its AI-powered video generation engine, and building out a formal partnership ecosystem. Herd was also a finalist in the inaugural Okta Startup Challenge in 2025, a signal of early credibility with the enterprise identity ecosystem before this raise.

Human Risk Market is Having Its Moment

The timing of this raise is no accident. The security awareness training market sits at an estimated $6.74 billion in 2026 and is forecast to hit $14.66 billion by 2031, growing at a 16.82% CAGR. Cybersecurity Ventures projects the figure could cross $10 billion annually by 2027 alone, driven by an explosion in AI-generated phishing content, deepfakes, and social engineering attacks that have made static, calendar-driven training programs dangerously obsolete.

The broader pressure on human risk management is being validated by investor dollars at every scale. Adaptive Security, a direct-ish competitor in the AI-driven security awareness space, raised a combined $146.5 million across a Series A and Series B by December 2025, with backing from Andreessen Horowitz, NVIDIA, Bain Capital Ventures, and notably the OpenAI Startup Fund, its only cybersecurity investment. That level of institutional conviction signals that the “human firewall” category has moved well past a niche and is now a mainstream enterprise spending priority.

Competitive Landscape

Herd Security carves out its lane against both legacy giants and well-funded newer entrants. The two most relevant direct competitors at a similar or adjacent stage in the AI-native security awareness space are Adaptive Security (New York) and Phished (Belgium/global), both of which offer continuous, AI-driven simulation and training, though with different architectural and go-to-market approaches.

Strategic Read

Herd Security wins on frictionless, in-workflow delivery and speed of content generation for security and GRC teams that need to stand up training without adding operational headcount. Adaptive Security, by contrast, leads in simulation depth and raw funding firepower, making it the stronger choice for enterprises facing sophisticated AI-driven impersonation threats rather than organizations looking to scale basic awareness at volume.

TechnoTrenz’s Takeaway

I’ll be honest: a $3 million seed round in isolation is not a headline that usually stops me mid-scroll. But Herd Security’s raise is one of those deals where the what matters more than the how much. In my experience covering enterprise security and SaaS funding cycles, the companies that win in crowded markets are rarely the ones with the deepest pockets on day one. They’re the ones who correctly diagnose a broken workflow and replace it with something employees will actually use. I think that’s exactly what Brandon Min and team are doing here.

The insight powering Herd is brutally simple: annual compliance training does not work, and everyone in the security industry already knows it. What is new is that agentic AI now makes it economically viable to generate fresh, relevant, personalized micro-training at the cadence threats actually move at. The fact that the platform lives inside Slack and Teams rather than asking employees to log into yet another portal is not a small design choice. It is the entire distribution moat.
