Aidan Cantu is an American entrepreneur and engineer who is the co-founder and chief technology officer (CTO) of F4 (also referred to as F4 Industries), a software platform that automates compliance checks for engineering drawings.[1] The company participated in Y Combinator's Summer 2025 batch and is based in San Francisco, California.
Career
Prior to founding F4, Cantu worked at SpaceX as an avionics engineer, where he was responsible for rocket engine component testing for the Starship program.[2]
Cantu co-founded F4 alongside other engineers with backgrounds at SpaceX and Tesla.[3] The company develops a platform aimed at hardware engineering teams that helps detect and fix drawing compliance issues before they cause downstream problems in manufacturing. F4 addresses a persistent challenge in hardware development: noncompliant or ambiguous engineering drawings that lead to scrap, rework, and miscommunication between design engineers and suppliers.
The F4 platform operates across several areas of the engineering drawing workflow. It automatically interprets geometric dimensioning and tolerancing (GD&T) symbols, datums, and notes according to relevant standards, ensuring that all stakeholders from design through manufacturing share a consistent interpretation of drawing intent. The platform also generates complete inspection plans directly from drawings, providing quality teams with specifications for what to measure and how, which reduces manual setup time and helps identify potential issues before first article inspection. Additionally, F4 extracts the information engineers need from drawings to set up tolerance analysis, including applicable features and rule exceptions, enabling teams to identify potential fit or function problems earlier in the design process.
The company operates in the B2B hardware and industrial sectors. F4 was accepted into Y Combinator's Summer 2025 batch, where it was categorized under the hardware, B2B, and industrial verticals.[4]
