As data volumes surge, servers and data centres face unprecedented pressure, pushing energy use sharply upward. Reportedly, server halls accounted for 1% of global energy consumption in 2021, a figure projected to reach 10% by 2030. Vesiro wants to change that trajectory.
The Gothenburg-based startup has raised €1.6 million in seed funding to tackle one of the fastest-growing challenges in global tech infrastructure: the spiralling costs and energy demand of large-scale data analysis.
The round was led by Chalmers Ventures with Industrifonden as co-lead, joined by Länsförsäkringar Göteborg & Bohuslän, Yuncture, First Gate Invest, E14 Invest, Mach One, and a strong group of angel investors, including Stefan Mahlstein, Staffan Truvé, Jan Sparud, Petter Eriksson, and Magnus Lundgren.
With the fresh capital, the team will expand its technical workforce, advance product development and accelerate its market rollout. As enterprises seek more sustainable ways to manage data growth, Vesiro enters the market at the right time with technology built for scale.
A solution for data-heavy industries
Oskar Hagman and Oscar Widén co-founded Vesiro in 2022. Both are alumni of Chalmers’ entrepreneurship program, and they joined hands with Swedish innovator Örjan Vestgöte, the mind behind the plugin’s core algorithm.
Founded at Chalmers University, the company has developed a performance-boosting AI-powered Elasticsearch plugin for companies managing vast search workloads. Instead of replacing infrastructure, the software unlocks more power from existing Elasticsearch clusters.
Early benchmarks show striking results, with searches running up to 3 times faster, enabling organisations to cut as many as half their servers. For businesses in fields such as e-commerce, business intelligence and AI, where Elasticsearch is central to operations. This means meaningful reductions in both cloud bills and environmental footprint.
Faster search, smaller footprint
The plugin accelerates search speeds to nearly double that of standard Elasticsearch deployments. By doing so, companies can perform the same tasks with far fewer machines.
This dual impact of cost savings and lower energy use comes at a moment when the industry is seeking practical, scalable ways to curb infrastructure emissions. Vesiro’s approach stands out because it doesn’t require migrating systems or rewriting applications. The performance gains plug directly into current setups, making adoption straightforward for enterprises under pressure to optimise.
“Data volumes are growing faster than today’s infrastructure can handle, and our technology makes it possible to analyse large datasets using far fewer servers. This lowers costs while also reducing energy consumption,” says Oskar Hagman, co-founder and CEO of Vesiro.
“Our focus is to make it easy for customers to get value from our technology. With our current solution, companies can achieve significant performance gains and cost savings while keeping their existing systems in place,” says Oscar Widén, co-founder and COO of Vesiro.
“Vesiro is a strong example of how advanced research at Chalmers can be turned into a scalable company, and this journey from idea to a well-funded seed round is exactly what we aim to enable for more entrepreneurs. Vesiro will impact sectors such as business intelligence and e-commerce. In the long term, it has the potential to help global tech companies become far more efficient, reduce their cost for hardware and energy use,” says Oskar Svarfvar, Seed Investment Manager at Chalmers Ventures.
“Vesiro has developed an innovative search algorithm that unlocks value for a broad set of customers struggling with the rapid growth of unstructured data. The solution shows strong potential as a highly scalable and easy-to-integrate addition to existing systems, and we are glad to welcome Vesiro to Industrifonden’s portfolio,” says Tobias Elmquist, Senior Investment Director at Industrifonden.
