Aidan Cantu is an American entrepreneur and engineer who co-founded F4 (also referred to as F4 Industries), a software platform that automates compliance checks for engineering drawings, and serves as its chief technology officer (CTO).[1] The company participated in Y Combinator's Summer 2025 batch and is based in San Francisco, California.
Early life and education
Cantu's educational background has not been publicly disclosed in available sources. Details regarding his undergraduate institution and field of study remain unconfirmed as of 2025.
Career
Cantu worked at SpaceX as an avionics engineer prior to founding F4. In that role he was responsible for rocket engine component testing for the Starship program.[2] The specific years of his tenure at SpaceX have not been confirmed in public records.
He went on to co-found F4 alongside engineers with prior experience at SpaceX and Tesla.[3] The company targets hardware engineering teams and focuses on detecting and fixing drawing compliance issues before those issues cause downstream problems in manufacturing. It's a problem that has long plagued hardware development: noncompliant or ambiguous engineering drawings routinely lead to scrap, rework, and miscommunication between design engineers and suppliers. F4 is built to address that gap.
The 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 standards including ASME Y14.5, so that all stakeholders from design through manufacturing share a consistent interpretation of drawing intent. The platform also generates inspection plans directly from drawings, giving quality teams clear specifications for what to measure and how. That reduces manual setup time and helps identify potential issues before first article inspection. F4 also extracts the information engineers need to set up tolerance analysis, including applicable features and rule exceptions, so teams can 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] Y Combinator's standard deal at the time of the Summer 2025 batch provided participating companies with an initial investment in exchange for equity, though F4 hasn't publicly disclosed specific funding terms or valuation figures as of early 2025. No measurable customer outcomes, such as reductions in rework rates or volume of drawings processed, have been publicly reported by the company to date.
