Staff Full Stack Engineer

About Pay-i

At Pay-i, we are solving one of enterprise AI's most critical challenges: proving ROI of GenAI investments. While global GenAI spend races toward $600B by 2028, 72% of CIOs cite measurement and forecasting as their top blocker, and only 13% of business leaders report significant enterprise-level value from GenAI. We are the only platform that transforms every model call, prompt, and agent step into CFO-grade metrics, providing enterprises the financial transparency to identify winning use cases, optimize costs, and prove impact.

Founded by ex-Microsoft leaders with 20+ years of experience each, Pay-i is a seed-stage company backed by five venture capital firms and executive/C-suite angels from Microsoft, Twilio, Zoom, and more. If you are passionate about selling products that fundamentally change how enterprises scale their AI initiatives, join us in bringing the system of record for GenAI ROI to market.
