Gus Trigos is the Founder and CEO of Runtime (YC P26), a model-agnostic infrastructure layer that gives engineering teams the guardrails, sandboxes, and visibility to let anyone ship safely with coding agents.

Gus grew up across different countries, taught himself to code in high school, went on to work as a quantitative analyst at BlackRock, and later co-founded Mentum, a YC-backed AI startup acquired by Nuvocargo in 2025.

After his last company was acquired, Gus personally shipped 4+ full-stack products in 3 months using coding agents, discovering firsthand the infrastructure gaps that inspired Runtime.

Gus validated Runtime by interviewing over 40 CTOs and heads of product about rolling out coding agents, building a solution that works across Claude Code, Codex, and other leading models.

Runtime, backed by Y Combinator's Spring 2026 batch, enables non-engineers to go from idea to production PR in minutes, expanding who can ship software inside an organization.
