Rohan Vasishth and Faraz Siddiqi, both 23, quit their early-career jobs at Amazon and Microsoft earlier this year to launch Bluejay, an AI quality assurance startup based in San Francisco. Within months, the duo secured $4 million in seed funding, according to a Business Insider report.
The company, which recently graduated from Y Combinator’s Spring 2025 batch, focuses on testing and monitoring AI voice and text agents. Vasishth told Business Insider that the decision to step away from Big Tech was fueled by the sheer pace at which AI is evolving. “I don’t need to stay here for six years to learn about it,” he said. “In fact, I will learn about it probably faster by just doing it.”
Putting AI Agents to the Test
Bluejay stress-tests AI agents by creating synthetic customers who mimic real-world users, complete with varied languages, accents, and background noise. The platform claims it can simulate a month’s worth of customer interactions in minutes, offering companies a way to quickly identify weaknesses in their AI systems.
According to a LinkedIn post by Y Combinator, the company is tackling one of the most overlooked barriers to enterprise AI adoption: testing. “The key to widespread enterprise AI adoption is not better models. It’s a better test suite,” Y Combinator noted.
A Hacker House, a Scrappy Mascot, and a Vision
Operating from a San Francisco “hacker house,” the founders and their first engineer are building Bluejay with what Vasishth describes as a “super scrappy” mindset. Their lighthearted branding even saw them graduate from YC in bluejay onesies, while grassroots tactics like handing out flyers at conferences helped them stand out from better-funded competitors.
The company’s name, inspired by how bluejays in nature repeatedly signal danger, reflects its mission: constantly pinging AI agents to ensure reliability. Alongside testing, Bluejay also provides observability tools to monitor ongoing agent performance.
Bluejay’s $4 million round was led by Floodgate, with participation from Y Combinator, Peak XV, and Homebrew. Executives from AI firms such as Hippocratic AI, Deepgram, and PathAI also invested, highlighting growing confidence in the startup’s approach.
The funding will be used to expand Bluejay’s team, hiring developers, researchers, and sales staff as the company scales.
Betting on the Future of AI
Vasishth and Siddiqi believe the timing of their leap couldn’t be better. As they told Y Combinator, they expect that in less than five years, nearly every company in the world will rely on AI agents for customer interactions. Their goal: to position Bluejay as the “multi-modal trust layer” ensuring those agents work seamlessly.
Bluejay is entering a competitive field where companies like Braintrust, Arize AI, and Galileo are also vying to set the standard for AI agent testing. But with its fresh perspective, scrappy beginnings, and early traction with Fortune 500s and startups alike, the young founders are betting that their break from Big Tech was the right move.
