Vesiro

What Vesiro does

Vesiro AB is a Gothenburg-based software company spun out of Chalmers University of Technology in 2022 that builds a performance-enhancing plugin for Elasticsearch and OpenSearch deployments. The plugin installs via Elasticsearch's official plugin framework in minutes and requires no application code changes, no re-indexing, and no replacement of existing clients, SDKs, or dashboards (including Kibana). Internal benchmarks and third-party validation by RISE Research Institutes of Sweden indicate up to ~2–3x faster search performance, up to ~47% faster search times, and up to ~50% fewer servers required for equivalent workloads, which translates into up to ~46% reduction in server energy consumption. The underlying technology is covered by filed-pending patents on proprietary search optimization algorithms with stated applicability to AI-driven environments.

The company targets organizations operating large-scale Elasticsearch or OpenSearch clusters — including use cases in e-commerce, business intelligence, and AI data retrieval — that face rising infrastructure and energy costs. Its go-to-market combines a product-led motion (live benchmark on the website, downloadable plugin, self-serve install) with a sales-assisted enterprise motion gated behind a "Book a Demo" call-to-action, with pricing described as quote-based and aligned to cluster scale on an annual cadence. Revenue is generated through subscription/recurring licensing of the plugin; the company is currently at the early customer pilot stage with no disclosed production logos.

Vesiro has raised approximately $3.2M cumulatively, including a €1.6M / $1.9M seed round in February 2026 co-led by Chalmers Ventures and Industrifonden. The company is led by CEO & co-founder Oskar Hagman and co-founder & COO Oscar Widén, and has received recognition including the Techarena 2025 TOP46 Pitch Competition win, Forbes 30 Under 30 Europe (Widén), Breakit's "56 Hottest Startups in Sweden 2024," and a Vinnova grant to extend its search technology into AI applications.

Core offering

Vesiro develops and sells a performance-enhancing plugin for Elasticsearch and OpenSearch that installs directly on existing search cluster instances. The plugin delivers up to 2x–3x faster search throughput while reducing required server infrastructure by up to 50%, requiring no application code changes, no re-indexing, and no migration. It is sold as a licensed add-on deployed on customer infrastructure.

Product overview

Vesiro offers a single unified core product: the Vesiro Elasticsearch Plugin. This plugin is a performance-enhancing add-on for Elasticsearch and OpenSearch that increases search throughput, allowing organizations to achieve the same search workloads using significantly fewer servers. The product is deployed directly within existing Elasticsearch/OpenSearch instances using the official plugin framework, requiring no application code changes, no re-indexing, and maintaining compatibility with existing queries, data mappings, tooling, dashboards (Kibana), and security configurations. The technology is designed to address rising data center energy consumption and infrastructure costs for organizations operating large-scale search and analytics environments.

Expansion highlights5 records

Broad incumbents

• Elastic NV: Elastic NV develops and distributes Elasticsearch, the platform that Vesiro's plugin directly enhances. Elastic is a broad incumbent in the search and observability space and could either compete with Vesiro natively or restrict its plugin framework.
• OpenSearch: OpenSearch (AWS/Linux Foundation) is the open-source fork of Elasticsearch that Vesiro explicitly supports. It is a broad incumbent offering an alternative search platform with overlapping developer mindshare and customer segments.
• Algolia: Algolia is a SaaS search and discovery platform that delivers hosted, low-latency search as an API. It is a broad incumbent serving similar developer and product owner personas as Vesiro's customers, with a managed-service rather than self-hosted model.
• Coveo: Coveo is an enterprise search and generative AI relevance platform serving commerce, customer service, and workplace use cases. It is comparable to Vesiro as an enterprise-facing layer that monetizes AI-enhanced relevance on top of underlying search infrastructure.
• Lucidworks: Lucidworks builds enterprise search and product discovery solutions on top of open-source search engines including Solr and Elasticsearch. It is comparable to Vesiro as a higher-level relevance/optimization layer for large enterprise search deployments.
• ClickHouse: ClickHouse is a column-oriented real-time analytics database increasingly used for search and log analytics workloads that historically ran on Elasticsearch. It is a broader infrastructure incumbent competing for the same compute-and-cost-conscious workloads Vesiro targets.

Emerging players

• Quickwit: Quickwit is a Rust-based open-source search and analytics engine positioned on cost-efficient, cloud-native search performance. It overlaps with Vesiro's value proposition of faster, cheaper search infrastructure, particularly for log and observability workloads.
• Typesense: Typesense is an open-source typo-tolerant search engine optimized for speed and developer experience. It is comparable to Vesiro as a performance-focused search alternative targeting developers and product teams with low-latency retrieval needs.
• Meilisearch: Meilisearch is a lightweight, open-source search engine built around speed and ease of integration. It competes in the same end-user-facing search experience layer that Vesiro customers care about, albeit via replacement rather than plugin optimization.
• Rockset: Rockset is a real-time search and analytics database built for low-latency queries on fresh data. It overlaps with Vesiro's positioning around faster, more cost-efficient search and is a potential alternative architecture for customers evaluating Elasticsearch optimization.
