Alexander Stroe is a Canadian entrepreneur and software engineer, best known as the co-founder of Patent Watch, an artificial intelligence platform built to automate the detection of patent infringement. He founded the company alongside Andreas Stroe in 2025. Patent Watch is headquartered in Toronto, Ontario, Canada, and was accepted into Y Combinator's W25 batch, one of the world's most competitive startup accelerator programs.[1][2]

Patent Watch

Patent Watch was co-founded by Alexander Stroe and Andreas Stroe in 2025. The company's origins trace directly to Andreas Stroe's experience conducting research at Philips, where he was involved in filing four patents. The patent filing process exposed both founders to the substantial complexity and manual effort required to monitor patent rights and identify potential infringement, which motivated them to develop a software solution to address those challenges.[3]

The platform uses artificial intelligence to streamline patent infringement detection. Patent infringement monitoring has traditionally demanded significant legal and technical expertise, typically requiring attorneys or specialized analysts to manually review patent claims and scan for potential conflicts. Patent Watch applies automated tools to perform much of this analytical work, with the aim of reducing the time and cost involved in protecting intellectual property rights.[4]

The company secured early institutional recognition when Patent Watch was accepted into Y Combinator's W25 batch, a competitive startup accelerator program that historically accepts only a small fraction of applicants.[5] Y Combinator, based in San Francisco, California, has backed companies including Airbnb, Dropbox, and Stripe, and acceptance into one of its batches is widely regarded as a significant validation for early-stage startups. As of 2025, Patent Watch employed four people and operated out of Toronto, Ontario.[6]
