Abdullah Nauman is Co-Founder of Antigen (YC F25), an AI-powered continuous offensive security platform built for enterprise clients across financial services, healthcare, retail, and government.

Abdullah studied Computer Science and Engineering at the University of Michigan, took a year off college to join as the second employee at a YC startup, and went on to build ML infrastructure and product at Google Search and Google Ads.

At Google, Abdullah led a 4-person team that built a DNN-based ML infrastructure for conversion modeling, driving over $1B in revenue in 2024, and also researched high-energy physics models at CERN and BNL, presenting at Supercomputing 19.

Prior to Antigen, Abdullah independently scaled a bootstrapped SaaS to $30K MRR, wrote low-level imaging software for silicon wafer manufacturing, and founded Powell St, a curated community for engineers and designers.

Antigen, backed by Lightspeed, DST Global, Susa Ventures, and Y Combinator, delivers nightly automated offensive testing and monthly human red team assessments, helping enterprises continuously map, exploit, and secure their attack surfaces.
