H+Trace, founded in 2021 by Argentinian entrepreneurs Javier Cuello and Ivan Fardjoume, is modernizing how blood and other biological samples can be safely transported to labs for analysis. The company’s goal is to eliminate human errors with its proprietary AI-powered technology.
The startup’s Contactless MultiSense (CMS) is a hardware and software platform that tracks and verifies samples from collection through analysis. The smart monitoring technology records the temperature of the vials and can sense if any have been tampered with, shaken or mishandled.
Over the past 18 months, H+Trace has collected and delivered over 11 million samples throughout Argentina, Mexico and the Dominican Republic. They’ll be starting in Brazil and in the U.S. soon.
“What surprised us was learning that two out of three laboratory errors happen before the sample gets analyzed, between the moment the blood is drawn until it reaches the analyzer,” said Cuello. “We understood that improving that process required data but we found no device and no technology in the market to provide us with that data, so we took a step back and created each smart device from scratch.”
Now, with $500,000 in pre-seed funding they recently raised to support expansion and continued product development, the co-founders plan to make downtown Miami their headquarters for their US operations and bring their technology to hospitals and clinical labs across the country.
H+Trace’s funders include Techstars, two family offices in Argentina, and a general partner at NXTP Ventures. “H+Trace shines a light on a hidden yet critical part of the diagnostic journey. It focuses on what happens before analysis. Their team and technology deliver real value in a space many overlook,” said Techstars Managing Director Andres Barreto, in a statement.
In the US, H+Trace hopes to start with at-home blood collections in retirement homes this fall.
“While we are developing a machine-learning algorithm to use AI to predict errors, we’ll mainly use the money for growth,” says Cuello of the company’s plans to increase their team of seven to 20, and to further develop smart technology for their devices.
Why Miami? “One of the biggest challenges we have as a startup is to attract talent. Miami attracts talent not only from the U.S. but also from Latin America and Europe,” said Cuello, who participated in the 2025 spring EndeavorLAB accelerator cohort, part of Endeavor Miami. “It’s very easy to serve not only the U.S. but also Latin America from Miami.”
While the components of the devices come from other countries, the devices are assembled in Hialeah. H+Trace currently has four devices powered by AI technology that monitor temperature and detect tampering. The data is transmitted from the devices to the Cloud through H+Trace’s mobile app, which gives users real-time information.
The idea to create H+Trace came about when Cuello’s friend was mistakenly diagnosed with gestational diabetes during her pregnancy with twins. She received another woman’s results and was told she had to lose weight, which she did, putting her pregnancy at risk.
“That’s when I when I asked myself, ‘How come mistakes like this still happen?’ That led me to dive deep into the healthcare supply chain, especially in the laboratory space and that’s when I put together the team that is now H+Trace,” Cuello said.
Cuello was one of the pioneers for using fiberoptics to record live concerts in Latin America, working with the Rolling Stones, ACDC and Madonna, and he sold the company in 2016. He also served as the head of science, technology and innovation for the City of Buenos Aires.
He met Fardjoume, also a serial entrepreneur, in 2018 during a Motorola competition. Cuello was the judge and Fardjoume was the head of technology for the contest. Today, Fardjoume runs H+Trace’s tech team in Argentina.
“I think that community impact is extremely important,” said Cuello. “That’s what we’re trying to solve with the retirement facilities and retirement communities in the Miami area.”
