FlexAI is building the next generation of AI cloud infrastructure, one that is software defined and optimized for modern AI workloads. As the era of raw GPU deployments gives way to platform driven AI infrastructure, FlexAI provides the foundation for the next phase of scalable AI systems. The platform is powered by our foundational layer built on Cloud Foundry, while the FlexAI Cloud Services layer provides a unified control plane that enables developers and enterprises to run AI inference and fine tuning across any cloud, accelerator, or data center without managing infrastructure complexity. With FlexAI, startups deploy securely and cost effectively in hyperscaler and neocloud environments, neocloud providers transform GPU clusters into scalable AI factories, and enterprises power governed private AI clouds. By decoupling AI workloads from the underlying hardware, FlexAI enables organizations to deploy AI faster, improve compute efficiency, and avoid vendor lock in.

At NcodiN, we are redefining how chips communicate. We unlock a new era of ultra-fast, energy-efficient optical interconnects, powered by a breakthrough technology: the world’s smallest laser integrated on silicon. This means AI hardware that is smaller, faster and dramatically more efficient, enabling limitless scalability while consuming less power. In a world that demands speed, optical interconnects are the express lanes of the future, built for AI’s full potential. The shift is inevitable, and at NcodiN we are making it happen.

i-Virtuals mission is to democratize remote, touchless vital sign measurement, making it accessible to industries across the board and transforming how vital health information is captured and leveraged. As leaders in signal processing, computer vision, and artificial intelligence, i-Virtual has developed innovative technology that enables vital sign measurements through a simple, contactless process. We were the first in the world to receive CE Class IIa certification for a medical device that captures key physiological data—including heart rate, heart rate variability, breathing rate, and stress level—from a 30-second video selfie. This list will continue to grow as we further enhance our technology and enter new markets. We are now expanding our offering with a powerful API, enabling application and platform developers across various industries to integrate our technology with shorter time-to-market and less overhead. This empowers developers to significantly enhance their solutions with touchless vital sign measurement capabilities, while making health data more accessible and actionable across diverse markets.
