Brandon Veiseh is Co-Founder and CEO at MindFort AI (YC X25), an autonomous AI security agent platform that finds, validates, and patches vulnerabilities in web applications at machine speed.

Brandon studied Political Science and Economics at UC Santa Barbara, then built deep expertise in cybersecurity product development, previously founding an NLP startup before pivoting into security.

Brandon led the development of the Nuclei cloud platform at ProjectDiscovery, transforming an open-source tool into an enterprise-ready product, and later built generative AI tools for human penetration testers at NetSPI.

His hands-on work across both a security scanner company and one of the world's largest pen testing firms gave him firsthand insight into the challenges of securing attack surfaces at scale, directly informing MindFort's product vision.

MindFort graduated from Y Combinator's X25 batch, secured a preemptive $6.2M investment from General Catalyst before Demo Day, and reached $220K in early revenue, with its platform already finding real vulnerabilities in production systems that legacy tools miss.
