Here is May's Digital Patholog Roundup with Imogen Fitt of Signify Research.

1. Digital Pathology as a Service (DPaaS): Histofy and Source BioScience announced a strategic partnership to enhance diagnostic workflows, starting with efficiency improvements and later expanding to deploy Histofy’s AI tools across Source’s UK-wide operations. Notably, Source BioScience is the UK’s largest histopathology provider and had previously acquired LD Path in 2022. This move reinforces the emerging trend of service-based digital pathology models, as seen with Inify Laboratories and PathologyWatch.

2. Platform Integrations: French AI company Bioptimus launched its H-optimus-1 model on AWS Marketplace, improving accessibility for life sciences. Meanwhile, Labcorp introduced an integrated digital pathology platform across its central labs, combining Leica Biosystems’ Aperio GT450 scanners with Proscia’s Concentriq LS system. The initiative aims to streamline scanning, archival, and companion diagnostic development for global clinical trials.

3. Artificial Intelligence: At Microsoft’s #Build2025, the company launched its Healthcare Multi-Agent Orchestrator, which includes Paige's Alba co-pilot for image-based pathology queries. Additionally, PictorLabs partnered with PathPresenter to integrate AI-based virtual staining into PathPresenter’s platform. Users can now apply virtual H&E, IHC, and special stains instantly on whole slide images for education, research, and clinical use—though FDA approval is still pending for PictorLabs’ solution.

4. Funding: Medmain Inc. raised $3.3 million to enhance its PidPort image management system, expand infrastructure, and pursue regulatory approval for its AI tools. This brings 2025’s total Digital Pathology VC funding to $168 million across 10 vendors, reflecting strong investor interest.
