- The funding round was led by Quiet Capital and included investments from Sequoia Capital and Omri Casspi's fund.
- The company's platform is built to handle massive data volumes and the demands of the AI era.
- Edelbyte's technology consolidates analytics, search, and AI workloads onto a single infrastructure.
- The startup currently employs approximately 40 people across Israel, Europe, and the US.
- CEO Avner Aharoni stated current systems are ill-equipped for AI-driven data query growth.
Edelbyte, a data infrastructure company founded by four former Microsoft engineers, has secured $45 million in a funding round led by Quiet Capital. The investment also saw participation from existing investors and new ones, including Gil Ofer's QP Ventures, Startpoint Capital, and Cerca Partners. A prior seed round of $25 million was led by Sequoia Capital with participation from Greenoaks and Swish Ventures, the venture capital fund of Omri Casspi.
The latest funding values Edelbyte at $500 million. The company was established in November 2025 by CEO Avner Aharoni, CTO Yevgeny Reizik, VP of Engineering Alexander Slutsky, and VP of Platform Engineering Yoni Leibovich. Reizik and Slutsky were part of the original team that developed Kusto, a data platform that originated as an internal Microsoft project and formed the basis for technologies like Azure Data Explorer, Sentinel, and Defender.
Edelbyte's platform is designed to handle massive data volumes and the query loads of the AI era. It allows for traditional analytics, text search, spatial queries, and AI workloads on a single infrastructure, reducing the need for separate systems and data duplication. The company states its architecture significantly compresses data, minimizing storage and processing requirements. Edelbyte's system can deliver results in milliseconds, handle thousands of concurrent queries, and index all data for ad-hoc queries, unlike systems with pre-defined indexes.
"The systems organizations use today for searching and analyzing information were built long before the AI era," said Avner Aharoni, Edelbyte's co-founder and CEO. "But as AI becomes a more central part of organizations' operations, the number and complexity of queries are growing at a pace that existing infrastructures were not designed to handle."
Edelbyte currently employs around 40 people across Israel, Europe, and the US. It operates petabyte-scale systems for Fortune 500 companies and global organizations in cybersecurity, automotive manufacturing, and finance.
