# Velum Labs

> Velum Labs is a Y Combinator-backed San Francisco startup building an operating system for data quality. Its platform continuously watches a company's data stack, catches when metrics and definitions diverge, traces the root cause through query lineage, proposes automated fixes, and then writes enforceable data contracts so the same break does not recur. Founded in 2025 by Chilean-born childhood friends Benjamin Munoz-Cerro (CEO) and Alen Rubilar-Munoz (CTO), the company is already in production at regulated fintechs monitoring 200+ tables tied to more than $1B in assets.

- **Founded:** 2025
- **Headquarters:** San Francisco, California, United States
- **Founders:** Benjamin Munoz-Cerro (Co-Founder & CEO), Alen Rubilar-Munoz (Co-Founder & CTO)
- **Team size:** 2 (per YC); the company has described a small team of scientists and researchers
- **Products:** Velum Semantic Control Plane / Data Quality OS, Divergence Detection, Root Cause Analysis, Automated Data Contracts
- **Notable:** Accepted into Y Combinator (F25/W26 batch, pre-classified as P26)., In production at regulated fintechs monitoring 200+ tables tied to $1B+ in assets under management across 2 countries., Founding team with backgrounds spanning Stanford physics, Harvard/Max Planck reinforcement learning for quantum computing, and geometric deep learning.

## Products & services

- **Velum Semantic Control Plane / Data Quality OS** — Continuously monitors query patterns, value distributions and schema changes to detect divergence, traces root cause through a live query-lineage dependency graph, proposes and deploys fixes through existing git/dbt/CI-CD workflows, and auto-generates enforceable data contracts from real problems.
- **Divergence Detection** — Continuous monitoring of query patterns, value distributions and schema drift across the stack.
- **Root Cause Analysis** — A live dependency graph built from production query traffic that shows which teams and queries depend on which data.
- **Automated Data Contracts** — Enforceable rules generated from actual breaks rather than hand-written YAML, deployed to prevent recurring failure classes.

## Achievements

- Accepted into Y Combinator (F25/W26 batch, pre-classified as P26).
