Granulate, an Israeli startup, has raised $12 million in a Series A funding round led by Insight Partners, with participation from TLV Partners and Hetz Ventures. The company offers a solution to optimize infrastructure usage and claims it can reduce infrastructure costs by 20% to 80%. Granulate achieved this efficiency by studying how Linux virtual machines operate and leveraging the Linux kernel's optimization for resource fairness. The founders focused on repetitiveness rather than fair allocation, aiming to optimize the machine for specific functions. Granulate's solution, which can be applied to virtual machines, containers, or pods, optimizes decision-making based on a utility function without requiring code changes. The solution also incorporates machine learning to continually improve performance optimization over time. Insight Partners recognized the potential of Granulate's offering, particularly in the current environment where high-performance digital experiences and cost reduction are crucial. Granulate plans to use the funding to expand its team from 20 employees to 40 by the end of 2020.
