When someone gets a lab test, most people think the hardest part is waiting for the results. But for Javier Cuello, CEO and co-founder of H+Trace, the real danger happens before the test is even run.
“Two-thirds of lab mistakes happen before analysis,” Cuello said. “That means lives are affected by something as simple as a mislabeled or poorly handled sample, and no one’s talking about it.”
H+Trace, now headquartered in Miami after growing out of Argentina’s Innovation Park, is tackling this problem directly. The startup has built a platform called Contactless MultiSense, or CMS, a hardware and software system that automates how lab samples are tracked, handled, and prioritized before they ever reach a testing machine.
With more than 11 million samples already tracked and partnerships forming across Latin America, H+Trace is bringing its tech to the U.S. The lean, seven-person team is leading U.S. expansion from South Florida, where the company is in conversations with hospitals, labs, and research institutions ready to modernize one of healthcare’s most error-prone systems.
Cuello, a serial entrepreneur with a background in drone and public sector innovation, launched H+Trace after a close friend was misdiagnosed at a leading hospital in Argentina. What started as a personal investigation into the medical error turned into a mission to rebuild trust in diagnostics, beginning with the part of the process few ever see.
“We saw a huge blind spot,” he said. “Everyone’s focused on testing, but we wanted to fix what happens before that.”
The CMS platform is fully contactless and AI-powered, combining sensors, traceability tools, and integrated software to oversee a sample’s journey from collection to analysis. It flags abnormalities, reduces waste, and ensures samples are processed efficiently and accurately.
Now the company is developing its most ambitious update yet: Agentic AI, a decision-making system that introduces autonomy to lab workflows. Rather than simply logging data, Agentic AI can identify high-priority cases, optimize technician workloads, and learn from behavior over time. Cuello envisions a future where labs not only process samples but actively protect the integrity of the diagnostic process.
“We’re not trying to replace what labs already do well,” he said. “We’re strengthening the weakest link in the chain. If we can make sure every sample starts with clean, verifiable data, we make the entire healthcare system smarter.”
Miami is central to that plan. Cuello views the city as more than just a point of entry into the U.S. market. He sees it as a strategic hub that connects Latin American innovation with U.S. healthcare systems and public institutions.
“Miami understands scale and complexity,” he said. “It’s global, it’s fast, and it’s forward-thinking. That’s what H+Trace needs right now.”
The company is already in talks with local labs and exploring pilot programs in the U.S. Eventually, Cuello believes CMS could be used in national testing labs, outpatient clinics, and even at-home diagnostic kits. With a partnership in place with Siemens Healthineers and a working prototype of Agentic AI already in development, H+Trace is focused on impact.
“Our goal is simple,” he said. “We want every diagnosis to begin with trust. And that starts with getting the basics right.”
By addressing the most overlooked point of failure in diagnostics, Javier Cuello and his Miami-based team are setting a new standard for how healthcare systems everywhere can protect patients before a single test result is delivered. In Cuello’s view, the future of diagnostics isn’t just about faster results. It’s about making sure we can believe in them.xecution paired with long-term vision.
