Sarthak Singh Chauhan is an Indian-born entrepreneur and software engineer based in San Francisco, California. He is the co-founder of Lanesurf, a voice AI company that automates freight booking for logistics brokers. Lanesurf was part of the Y Combinator Summer 2025 batch.[1]
Career
Education and early work
Chauhan studied engineering at the Indian Institute of Technology Delhi (IIT Delhi). While an undergraduate, he co-authored research on transformer-based machine learning models before large language models became widely adopted, collaborating with research groups at the University of Waterloo and Monash University.[2]
Chauhan subsequently built an inference application for compute-intensive machine learning models that was reportedly ten times faster than existing state-of-the-art solutions. The underlying algorithm was adopted by the research arm of a Fortune 100 biopharmaceutical company. He also participated in iGEM, an MIT-affiliated research initiative focused on computational protein design, where his team was awarded a gold medal among more than 3,000 competing teams globally.[3]
Lanesurf
Chauhan co-founded Lanesurf in 2025 alongside Pratham Bansal, also an IIT Delhi graduate. The company develops voice-based artificial intelligence systems designed to automate the process by which freight brokers find, vet, and book carriers for shipments.[4]
Lanesurf's AI coordinator can simultaneously conduct over 100 carrier calls in parallel, negotiating rates within predefined limits and performing compliance checks. These checks include verifying phone legitimacy, dispatcher history, Federal Motor Carrier Safety Administration (FMCSA) registration, certificate of insurance status, and driver location. The system uses real-time signals such as carrier lane preferences, fuel prices, and weather data to optimize pricing. According to a case study published by the company, a produce brokerage client reduced booking time by 80 percent and increased margins by 8 percent using the platform.[5]
The company describes its AI as self-improving: with each booking, the system learns from aggregated and anonymized lane and pricing data, with the goal of building a voice-driven freight marketplace. As of late 2025, Lanesurf had four employees and was based in San Francisco. The company's clients include providers serving Walmart, Sysco, and Lipman Family Farms.[6]
