Benjamin Muñoz-Cerro is Co-Founder and CEO at Velum Labs (YC F25), an open-source firewall platform that enforces content-level access control across documents, databases, and AI workflows. The company builds privacy-preserving infrastructure using homomorphic encryption to protect sensitive data in enterprise AI systems.

Benjamin studied Physics and Mathematics at Stanford University, graduating in 2025. During high school in Chile, he built a low-cost subatomic particle detector and won first place nationally for developing a UV overexposure wound visualization system.

Benjamin's research project on low-cost graphene detectors for studying electron and positron beams was selected among the top 26 projects globally. He was selected as 1 of 40 participants from over 400 applicants across four Latin American countries for a scientific leadership program.

Velum Labs raised $500K in pre-seed funding from Y Combinator and is building for hospitals, banks, and government teams requiring HIPAA-compliant AI solutions. The platform provides encryption and structure-preserving tokenization for high-throughput data pipelines.

Velum's firewall sits between data sources and consumers (LLMs, users, vendors), enforcing policies in real-time to prevent sensitive information from leaking. The platform integrates with enterprise systems like Salesforce, SAP, and Workday to control access across entire technology stacks.
