AI data firm Edelbyte closes a $45 million Series A funding round, with a valuation of $500 million.

Data infrastructure firm Edelbyte has secured a $45 million Series A funding round, valuing the company at $500 million. The round was led by Quiet Capital, with full participation from all existing investors; new backers include QP Ventures, Startpoint Capital, and Cerca Partners. Prior to this, Edelbyte raised a $25 million seed round led by Sequoia, with follow-on investments from Greenoaks and Swish Ventures, bringing its total capital raised to $70 million. Founded in November 2025 by four former Microsoft engineers, Edelbyte builds a data platform designed to handle the increasingly complex query workloads of the AI era. Co-founders and key executives Avner Aharoni (CEO), Evgeney Ryzhyk (CTO), Alexander Sloutsky (VP of Engineering), and Yoni Leibowitz (VP of Platform Engineering) each have roughly 20 years of tenure at Microsoft, with over a decade of collaborative experience. Notably, Ryzhyk and Sloutsky were part of the founding team of Microsoft’s internal data platform Kusto, a technology that later served as the foundation for products including Azure Data Explorer. Edelbyte’s platform unifies traditional analytics, text search, spatial queries, and AI workloads on a single infrastructure, and can be deployed across public cloud, private cloud, and on-premises environments.
