About uRun

uRun provides an infrastructure layer designed for interactive and real-time generative AI. The company was founded in 2023 by former Google engineers Tim Shi and Amir Fathollahzadeh and is a participant in Y Combinator's W24 batch.The founders' backgrounds are deeply rooted in large-scale deep learning systems. Tim Shi holds a PhD in Computer Science and was a Staff Software Engineer at Google, contributing to Search, Ads, and internal deep learning platforms. Amir Fathollahzadeh also worked as a Senior Software Engineer on Google's deep learning infrastructure for Search after a tenure as a Quantitative Researcher. Their collective experience revealed a critical bottleneck in generative AI: the stateless nature of inference. Traditional systems process each user prompt as an isolated event, reloading the model and the entire conversation history, which introduces significant latency.uRun addresses this challenge with its core product, a stateful inference runtime. This technology maintains an active session for each user, keeping the model and conversational context loaded in GPU memory. As a result, subsequent interactions are processed instantaneously, eliminating the lag typically experienced in AI conversations. This allows developers to build highly responsive and steerable AI agents, copilots, and creative tools that feel truly interactive.The company targets developers and businesses in the B2B market that require low-latency, production-grade generative AI applications. The business model is centered on providing its specialized infrastructure as a service. By solving the persistent state problem, uRun enables a new class of real-time AI products that were previously not feasible.
