Ambio raises €5.1 million for recycled plastics platform

Helsinki-based startup Ambio, which develops an AI-native procurement platform for recycled plastics, has raised €5.1 million in a Seed round led by b2venture, with participation from Montis and existing investor Lifeline Ventures. Founded in 2023 by Tommi Bergström and Elmo Pakkanen (former Slush team members), Ambio addresses fragmented supply, inconsistent quality, and manual processes by acting as a principal in transactions, taking responsibility for sourcing, quality assurance, and delivery. The platform combines verified materials, structured quality data, AI-powered matching, and supply chain management, using LLMs to interpret unstructured data. Serving customers in the Nordics, German-speaking Europe, and recently France, the funds will support international expansion and scaling across polymer types, positioning Ambio as the central trust layer and marketplace for recyclates in Europe.

Calliora raises $6M for AI hospital billing accuracy

Munich-based startup calliora has raised $6 million (approx. €5.1 million) in a pre-seed round led by Bertelsmann Healthcare Investments (BHI) and Swiss VC redalpine. The company's AI platform helps hospitals find billing errors before invoices are sent to health insurers. This comes as German hospitals face stricter audit quotas from 2027 under the GKV contribution rate stabilization law, where high error rates could lead to 100% of invoices being audited. The platform integrates with existing hospital systems, covering coding, case review, MD audit management, and controlling. According to calliora, the platform is already in regular operation in hospitals across five German states, reducing per-case workload by over half and closing more than 90% of identified gaps before billing. The funds will be used to grow the AI, engineering, and product teams. The startup was founded in 2023 by Frederik Träuble and Jonas Wildberger.
