23-year-old cofounders left Amazon and Microsoft to build an AI startup. Read their Y Combinator pitch deck.

In an inspiring move, two 23-year-old engineers, Rohan Vasishth and Faraz Siddiqi, recently departed from their positions at Amazon and Microsoft to embark on an entrepreneurial journey with their new venture, Bluejay. Based in San Francisco, this AI startup has successfully raised $4 million in seed funding to enhance its focus on quality assurance for AI agents, particularly voice-based systems. Vasishth and Siddiqi, who graduated from Y Combinator's spring 2025 batch, are driven by the rapid evolution of AI technology. Vasishth shared his motivation for leaving a stable job, stating, "I don't need to stay here for six years to learn about it. I'll probably learn even faster by diving right in." The seed funding round was led by Floodgate, with additional contributions from prominent investors like Y Combinator, Peak XV, and Homebrew. Notable executives from companies such as Hippocratic AI, Deepgram, and PathAI also backed Bluejay, underscoring the startup's potential in the burgeoning AI sector. Bluejay specializes in stress-testing AI agents by simulating a diverse array of customer interactions. This includes accommodating various languages, accents, background sounds, and personality types, allowing the company to replicate a month’s worth of AI interactions in just minutes. The founders have set up operations in a San Francisco "hacker house" with their initial hire, a founding engineer, reflecting their commitment to a collaborative and innovative work environment. Their approach is marked by a “super scrappy” philosophy, which is evident in their lighthearted branding and unique mascot. For instance, they wore bluejay onesies during their graduation from Y Combinator and utilized grassroots marketing strategies, such as distributing flyers, to stand out in a competitive landscape. In addition to their testing services, Bluejay also assists clients in monitoring the performance of their AI agents. With the new funding, the startup plans to expand its team by hiring developers, researchers, and sales personnel to further its mission. Bluejay is entering a competitive market filled with other companies like Braintrust, Arize AI, and Galileo, all eager to capitalize on the growing demand for AI agents. The pitch deck they used to secure their funding features key insights and strategies, with certain slides adjusted for public sharing.
