Greptile, founded by three current and former �鶹�� Tech students, has quickly emerged as one of Silicon Valley’s most promising young technology companies. The startup, led by Daksh Gupta, CS 2023; Soohoon Choi, CS 2023, MTH 2023; and computer science major Vaishant Kameswaran, builds artificial intelligence tools that help engineering teams review, analyze, and improve their code. 

Since its launch in 2023, the company has gained traction with more than 2,000 customers, including Brex, Whoop, and Substack. In 2024, Greptile raised $25 million in Series A funding from Benchmark, bringing its total capital raised to $30 million and valuing the company at $180 million. That same year, Greptile was also accepted into the winter 2024 cohort of Y Combinator, the startup accelerator that helped launch Airbnb, Dropbox, and Stripe.   

For Gupta, the road to building Greptile began at �鶹�� Tech. The founders entered �鶹�� Tech’s CREATE-X Startup Launch program with an entirely different idea: an AI shopping assistant called Tabnam. But through the program’s customer-discovery process — an intensive cycle of testing, feedback, and rapid iteration — the team realized their technology had stronger potential when applied to software development. That pivot became the foundation for Greptile. 

“CREATE-X did two things without which Greptile would not exist,” Gupta said. “It introduced me to my co-founder, Soohoon, and it gave us the confidence to consider starting a company as a real career path.”  

The founders credit the program with shaping their entrepreneurial thinking, but they describe Y Combinator as the force that helped propel their company to the next stage. Gupta says Y Combinator’s value mirrors some of what they found at �鶹�� Tech. “Like �鶹�� Tech, a lot of Y Combinator’s value comes from three things: being surrounded by ambitious people, gaining credibility, and having smart, accomplished people believe in you before you fully believe in yourself,” he said. “That combination does wonders for your self-esteem, which in turn has enormous compounding effects.”  

The company’s recent fundraising experience reflects this momentum. Gupta describes their investor pitches as “fast and painless,” noting that they entered the process with compelling metrics and a refined story. Today, the team is supported by an impressive roster of founders-turned-investors — including partners from Initialized Capital and Benchmark — who have helped the company hire talent and make key strategic decisions.  

Looking back, Gupta says the lessons from CREATE-X continue to guide their approach to building technology and scaling a company. “Y Combinator helped us scale, but �鶹�� Tech is where it started,” he said.
