Customisable digital labs for sovereign life-sciences data and AI
Assemble analysis pipelines from reusable method bricks so scientific workflows are reproducible and easy to share across teams.
Bring together data from instruments, files and external sources into one governed, traceable environment.
Choose cloud, on-premises or edge deployment so sensitive life-sciences data stays where governance requires.
Manage research projects, search across datasets and run analyses from a unified workspace built for scientific teams.

Real-time vision AI models and a full platform to train, annotate, and deploy them
One model family covering detection, instance segmentation, pose estimation, oriented boxes, classification, and tracking, tuned for real-time inference on GPU, CPU, and edge devices.
Label data with SAM-assisted annotation, train on cloud GPUs with AutoTrain, and deploy to managed regions that scale to zero when idle.
Ship trained models to ONNX, TensorRT, CoreML, TFLite, and many other formats for cloud servers, mobile devices, and embedded hardware.
Adopt the open-source AGPL-3.0 release, or purchase an enterprise license to embed YOLO in closed-source products without copyleft obligations.
