Leil Storage Raises €1.5M Seed to Scale Energy‑Efficient Enterprise Data Storage Solutions
Estonian data‑infrastructure startup Leil Storage has raised €1.5 million in seed funding to accelerate the development and market expansion of its energy‑efficient data storage software designed for hyperscale enterprise environments. The round was led by Karma Ventures, with participation from Specialist VC, signaling strong early investor confidence in the company’s mission to make cost‑effective and sustainable storage infrastructure accessible to a wider range of organisations.
Founded in 2022 by engineers Aleksandr Ragel and David Gerstein, Leil focuses on solving one of the most pressing challenges in the data age — how to store rapidly growing volumes of data more cost‑efficiently and with lower energy consumption. Leil’s software enables enterprises to unlock the potential of high‑density shingled magnetic recording (SMR) hard drives that were historically used only by hyperscale cloud providers due to their complexity.
The company’s technology manages how data is written, moved and recovered across thousands of SMR drives while retaining their higher storage density and reducing power use. By intelligently classifying content based on access patterns and powering down inactive drives until they are needed again, Leil’s software can significantly improve capacity and efficiency for data‑intensive workloads. This approach allows organisations to store roughly 20 % more data per disk and achieve substantial energy savings — in some cases up to 70 % on power usage — compared with conventional storage systems.
Leil’s product is tailored for enterprises that handle multi‑petabyte datasets, such as national broadcasters, public archives, research institutions and AI training centres. These organisations often grapple with rising storage costs and sustainability concerns as they expand their infrastructure to keep pace with exponential data growth. The company’s solution addresses both economic and environmental pain points by reducing hardware requirements, energy consumption, cooling needs and operational overhead.
Despite the explosive volume of data being generated globally — with hundreds of millions of terabytes created daily and projections indicating significant increases in the years ahead — many organisations struggle to adopt advanced storage architectures because of cost and complexity. Leil’s offering aims to bridge that gap, providing a software layer that makes SMR drives practical and manageable in enterprise contexts.
Leil operates under a capacity‑based subscription model, enabling companies to deploy its software alongside existing hardware and gradually integrate SMR drives over time. This incremental adoption approach helps organisations transition to more efficient storage without requiring a full infrastructure overhaul. The company’s roadmap includes expanding product capabilities and extending integrations with leading hardware vendors to support a broader range of use cases.
Karma Ventures, which led the seed round, has a track record of backing deep‑tech and enterprise software startups with global ambitions. In backing Leil, the firm emphasised the need for smarter, sovereign infrastructure to support data‑heavy applications such as artificial intelligence, where compute alone is not sufficient without equally capable storage. Specialist VC’s participation underscores continued interest from European investors in supporting next‑generation infrastructure solutions that balance performance, cost and sustainability.
Leil’s founders bring decades of combined expertise in storage infrastructure and systems engineering, positioning the startup to address foundational challenges in data management. CEO Aleksandr Ragel has described the company’s mission as democratising hyperscale storage economics by making high‑density, energy‑efficient storage capabilities accessible beyond the realm of massive cloud providers. By doing so, Leil aims to help organisations maintain control over their data while mitigating the environmental and financial costs of scale.
The funding will be used to accelerate go‑to‑market efforts, grow the commercial team and expand Leil’s product roadmap to meet the evolving needs of data‑intensive sectors. As enterprises increasingly look for ways to optimise infrastructure spending and align with sustainability goals, tools that can enhance storage efficiency — without compromising performance or data sovereignty — are gaining traction. Leil’s early traction and investor support position it to capitalise on this trend as demand for scalable, eco‑friendly storage solutions continues to rise.
With its seed round complete and a growing roster of customers in key industries, Leil Storage is poised to expand its reach across Europe and beyond, helping organisations navigate the growing complexity and cost pressures of modern data storage.
