Waiv has evolved to meet this moment: Hundreds of novel innovations are entering clinical development each year, while biomarker testing complexity and costs are surging. As healthcare undergoes a broader shift toward precision care, treatment decisions, monitoring strategies, and patient pathways increasingly rely on high-dimensional data and advanced diagnostics. Clinical diagnostics must keep pace with the scale and complexity of precision medicine, ensuring no patient is left behind. Waiv, a spin-out of Owkin (https://www.owkin.com/), capitalizes on its industry-leading tech & AI stack, and clinically validated, already-deployed AI tests, such as RlapsRisk BC (https://www.owkin.com/diagnostics/rlapsrisk-bc), to unlock morphological insights and future-proof the clinical diagnostic workflow.

On a mission to enable the edge AI products you dream of. AI at the edge is rapidly evolving. Novel models, such as LLMs, emerge quickly and make technological predictions challenging. At the same time, hardware solutions are diversifying and increasing in complexity. Traditional deployment methods cannot keep up with this pace and have become major adoption barriers for edge AI. They come with low adaptability, limited performance, and are painful to use. Roofline revolutionizes this process with a software solution that offers unmatched flexibility, top performance, and simplicity. Import models from any framework and deploy them across diverse hardware with just a single Python call.

At Emmi AI, we believe that the next frontier of industrial engineering lies at the intersection of artificial intelligence and physics. The world of large-scale engineering and manufacturing is ripe for transformation, yet todays innovation processes are hindered by slow, costly simulations and prohibitive computational requirements. Emmi AI is here to change that.

Kleio built the infrastructure of Agentic Commerce. At the core is the Knowledge Engine: five purpose-built data stores, product, pricing, customer, graph, and document, that give AI agents an accurate, structured foundation to reason over complex catalogs without hallucination. On top of it runs a fleet of thousands of orchestrated AI agents that handle the full sales journey, from need identification and product guidance to proposal generation and conversion, in real time. Each deployment is fully configurable: enterprises can run multiple agent configurations in parallel across brands, channels, or markets, and version them like software, testing, iterating, and rolling back with complete control. The result is a new category of commerce experience: immersive, self-generating interfaces that adapt to each customers intent, and an AI Cockpit that gives enterprise teams full visibility over every agent configuration, conversation, and outcome. We work with enterprises in travel, automotive, real estate, wholesale, building materials, and energy efficiency, with enterprise-grade security, seamless CRM and ERP integrations, and industry ontologies that are live in weeks, not months.

Meet DeepIP: The AI platform that helps patent practitioners save half the time and raise the quality of every patent, from idea to enforcement. Trusted by hundreds of organizations across five continents, DeepIP augments every stage of the patent lifecycle with an integrated, secure, intuitive platform that works where you work. At DeepIP, we’re driven by a simple belief: IP professionals should spend their time on strategy and innovation—not administration. The IP landscape is changing fast, and the tools supporting it must evolve even faster. Our mission is to build the AI technology that streamlines IP work, elevates the practitioner, and unlocks a new standard of quality, speed, and impact across the entire patent lifecycle. By pairing cutting-edge AI with deep collaboration across the global IP community, we’re helping practitioners move beyond outdated processes and into a future where human expertise and AI work seamlessly together to protect and propel innovation.

The open source AI SRE for autonomous incident investigation. Tracer investigates incidents before they you get pinged, filtering noise, correlating evidence across your stack, and producing an evidence-based RCA for the issues that actually matter. Tracer is built for SRE and platform engineering teams who are tired of endless loops. With graphs of your workflows, infrastructure, and telemetry, Tracer builds a complete picture of your systems, separating what matters from what doesn’t. With Tracer, multiple AI agents troubleshoot in parallel, test multiple root-cause hypotheses at once, and start investigating before your team even opens the alert.
