At Osto, we’re reimagining the way businesses approach cybersecurity. In a world where digital threats are evolving faster than ever, traditional security tools often fall short. That’s where Osto comes in. We’ve built an all-in-one cybersecurity platform that combines powerful protection with simplicity and scalability. Designed to eliminate the chaos of managing multiple disjointed tools, Osto brings everything under one roof—threat detection, API and system monitoring, access control, real-time alerts, and intelligent automation, all through a single, intuitive interface. Our mission is bold but clear: to democratize enterprise-grade security for businesses of all sizes. We believe that robust cybersecurity should not be limited to large enterprises with big IT teams. At Osto, startups, SMEs, and growing businesses get access to the same level of security—without the complexity. What sets us apart is our product philosophy: powerful tech that doesn’t feel complicated. We prioritize user experience, speed, and seamless onboarding, so your team can focus on building your business, not managing tools. But we’re not just building software. We’re building a culture of trust and resilience. Backed by a team of passionate engineers, designers, and security experts, we’re constantly evolving to stay ahead of threats and ahead of the curve. Whether it's adding new AI-driven capabilities or integrating with the latest platforms, innovation is baked into our DNA.

Language shouldn’t determine the quality of your care, but for 30 million patients in the U.S., it still does. Lexi is an early stage Harvard–backed startup building AI-native, real-time medical interpretation so clinicians and patients can communicate clearly across languages. Every day, clinicians lose precious time and patients face preventable risks because they can’t speak the same language, while traditional interpretation services remain slow, costly, and inconsistent in quality. For patients with limited English proficiency, this shapes every encounter with the health system. We’re building the real-time multilingual communication layer for healthcare to deliver instant, medically accurate, voice-to-voice interpretation using advanced speech processing and multilingual AI. Lexi is optimized for clinical workflows and engineered with HIPAA-grade privacy to protect patient data. Join us in making healthcare truly accessible for all!

Based on clinical whole genome sequencing (WGS) and using a single patient sample, Variantyx's Genomic Unity® test identifies and reports all major variant types including small sequence changes, structural variants, mitochondrial variants and short tandem repeat expansions. This comprehensive test test eliminates the need for traditional step-wise, reiterative genetic testing.
