Sidharth (Sid) Menon is Co-Founder and CEO of /dev/fast (YC W26), an AI-native code forge building next-generation code hosting, review, and deployment infrastructure for AI-heavy software teams.

Sid studied Computer Science at Harvard University and went on to serve as a tech lead on Palantir's cloud infrastructure team, where he built secure deployment infrastructure for untrusted workloads.

Sid brings deep expertise in secure cloud infrastructure and AI agent orchestration, positioning /dev/fast at the intersection of developer tooling and the AI-native software era.

Backed by Y Combinator in the Winter 2026 batch, /dev/fast was co-founded alongside Alex Iansiti, Ketan Agrawal, and Milan Bhandari, combining elite engineering backgrounds from Palantir, Snowflake, Pinterest, and Stanford.

/dev/fast's multi-agent software factory combines RFC-like code review, 2D diffs, trace storage, and agent orchestration, enabling engineering teams to review pull requests 10x the size in half the time.
