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.

HEAL (Healmenow Inc.) is building the first screenless, voice-first companion for medication adherence and mental wellness. Instead of another app competing for screen time, HEAL lives as a physical device in your space — you talk to it, it responds, it helps you stay on track with your care. We sit at the intersection of hardware, AI, and emotional design, because behavior change doesn't come from reminders and gamification — it comes from feeling understood. What We're Building A screenless medication adherence device paired with an AI voice companion. Say "Hey HEAL" and it dispenses your medication, logs adherence, and has a real conversation with you about how you're doing — building the kind of clinical documentation that qualifies for Medicare Remote Therapeutic Monitoring (RTM) reimbursement. V1 is built and working; we're now developing V2 using real user data, targeting a significant jump in treatment effectiveness. Our voice companion also carries a crisis-escalation layer, built with clinical oversight from a psychiatry advisor with 15+ years of experience. Hard Problems We're Solving Medication non-adherence, especially for mental health conditions, is a massive and under-addressed problem — people don't stop taking their medication because they forget, they stop because no one is checking in on how they actually feel. Existing solutions (pillboxes, reminder apps) treat this as a logistics problem, not an emotional one. We're solving three hard problems at once: designing a voice AI that can hold a caring, clinically-sound conversation without a screen; building the crisis-detection logic responsible enough to flag real risk without false alarms (the single highest-risk, highest-scrutiny part of the FDA classification question); and proving this new adherence data can actually satisfy Medicare RTM reimbursement requirements, which is what will make this sustainable at scale rather than another wellness gadget.

StarCast is building the trust, licensing, and rights infrastructure for the AI likeness economy. We enable creators to securely license AI versions of their identity (face, voice, and digital persona) to businesses while maintaining full ownership, approvals, pricing, usage rights, and restrictions. We're solving hard infrastructure problems around AI identity, consent verification, licensing, payments, authorization, and scalable AI workflows. Long term, we're building an AI Identity API and consent layer that AI platforms can use to verify whether a person's likeness is authorized before it is generated or deployed. This is a systems engineering challenge involving secure identity, distributed architectures, AI orchestration, enterprise workflows, and internet-scale infrastructure not just another AI application.
