Tallinn-based Leil builds data-storage infrastructure software that makes SMR hard drives practical at enterprise scale. SMR technology overlaps data tracks, delivering about 20 % more capacity per disk than conventional CMR drives, but it requires specialised, sequential-write management that most organisations lack. Leil’s platform automates how data is written, moved and recovered across thousands of SMR drives, classifying content by access patterns and powering down inactive disks to cut energy use by as much as 70 % for archive-heavy workloads. The solution improves cost per terabyte by roughly 20 % while lowering hardware, cooling and operational overhead, giving national broadcasters, public archives, AI training centres and research institutes hyperscale economics without proprietary in-house tools. The company sells its product on a capacity-based subscription and supports phased adoption so customers can integrate SMR drives alongside existing infrastructure. With the enterprise storage market estimated at $22 billion and growing nearly 20 % annually, Leil aims to position its HDD-native approach as a foundation for data-intensive AI and scientific workloads. Proceeds from its recent seed round will accelerate go-to-market activities, broaden the product roadmap and expand the commercial team.
