I would like to remind participants that during this call, management will make forward-looking statements, including without limitation, statements regarding our future performance, market opportunity, growth strategy, and financial outlook. In addition, today's discussion will include references to certain non-GAAP financial measures, including adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, cash flow from operations, and free cash flow. We delivered an exceptional first quarter with revenue and adjusted EBITDA ahead of guidance. Emerging revenues grew over 80% year-over-year and climbed to 14% of total revenues, aided by AgenticOS.
As a pioneer in AI, our multi-year investments are paying off and fueling new revenue streams, operating leverage, and market-leading advantages that are at the early stages of compounding. We're evaluated on our ability to monetize every ad impression we process, and we earn revenue only when we deliver superior results for publishers and buyers. As customers see stronger performance, they increase usage, creating a self-reinforcing model where greater adoption and utilization drive both customer ROI and our own profitable growth. By connecting ad demand and premium supply in a single environment, advertisers see higher ROI and publishers benefit from increased yield.
We're using NVIDIA Triton Inference Server to deploy real-time inferencing for bidding and audience decisioning. With faster processing, we are improving our proprietary model training in real time, resulting in significant performance improvements and better optimization for advertiser return on ad spend. Our growth profile mirrors this trend as we diversify our business and accelerate expansion beyond the largest DSPs. This is an exciting area of innovation and demonstrates how existing software interfaces are quickly becoming obsolete.
