  • VALIDIO

    Participated · Series A · Mar 2026

    Validio provides an agentic data management platform that continuously monitors, detects, and resolves data quality issues across large, complex datasets. Its system replaces thousands of manual, rules-based checks with automated anomaly detection, integrated data lineage, and cataloguing, giving both business and technical teams clear visibility into data problems. The platform is already used by data-intensive and regulated organisations such as Nordea, Canva, Deutsche Glasfaser, Truecaller, Surfshark, Walden, and AllianceBernstein. Validio reports strong growth in annual recurring revenue as enterprises seek more trustworthy data foundations to accelerate AI adoption and meet compliance demands. With the latest capital, the company plans to expand go-to-market operations in the US, UK, and Northern Europe, enhance product capabilities, and grow its team. To date, Validio has raised a total of $47 million in venture funding.

  • Kovant

    Led · Seed · Nov 2025

    Headquartered in Stockholm, Kovant has built a platform that lets enterprises spin up and manage entire departments composed of agentic AI workforces. Instead of relying on a single large language model, the system orchestrates many small language model-based agents, each operating within strict guardrails for accuracy, auditability and compliance. These agents can autonomously handle procurement, supply-chain, inventory management, compliance and customer success, completing month-long processes in as little as one to two days while escalating only when human judgment is required. The platform is designed for deployment in weeks rather than months and runs continuously, learning over time. Kovant is now launching globally and intends to promote an “agentic-first” operating model for enterprises of all sizes. With fresh capital, the company will expand its presence across the Nordics, Switzerland and the Benelux region. To date, Kovant has raised €1.5 million in pre-seed funding to fuel this growth.
