Haïm Dimer speaking

Haïm's journey spans continents and industries. From early work in software to founding startups in both the US and Europe, he has built a career blending technical innovation with people-centered leadership.

After nearly a decade leading digital transformation at Ramsay Medical Centers in Paris, growing the company from $57M to $125M in revenue, he founded Vudexis, a telemedicine startup that became profitable in under a year. Today he leads IT operations at Holman Logistics, driving automation and AI initiatives across 20 warehouses, while running Lifetria, a software agency that helps organizations build with AI.

It started in Paris, at Epita, one of France's most demanding computer science schools. This was the mid-1990s, the early days of the World Wide Web, and Haïm was immersed in Linux and the open source movement that would later reshape the entire software industry. After a few years, he moved to the United States and began teaching Linux and open source technologies at American Intercontinental University in South Florida, before joining Telefónica and then Akamai, where he implemented DDoS protection systems spanning servers across three continents.

The entrepreneurial pull came early. In 2003 he founded Green Backup, a data recovery company. After managing an internet service provider in Portland, Oregon, he returned to France for what would become an important chapter of his career: nearly a decade at Ramsay Medical Centers, the largest conglomerate of health centers in the country. As CTO and later CEO, he led the complete digital transformation of the organization, eliminating all paper medical files across dozens of facilities and designing infrastructure that served 2.3 million patient yearly.

In 2020, he founded Vudexis, a telemedicine startup focused on ophthalmology in medically underserved areas. It was profitable within its first fiscal year. That same instinct for building from zero carries through to Lifetria, his current software agency, which helps organizations adopt AI tools to ship faster and depend less on bloated enterprise software.

Alongside the technology career, Haïm has pursued documentary photography in some of the world's most difficult environments. In 2016, he joined MOAS aboard a rescue vessel outside Libyan waters, documenting the rescue of over 500 refugees crossing the Mediterranean. In 2022, a few weeks after the war started, he traveled to western Ukraine and Poland to photograph the refugee crisis. In 2023, he was in Israel collecting witness reports in the aftermath of October 7th. The camera serves a different purpose than the keyboard, but both are rooted in the same impulse: to see clearly and to tell the truth about what's there.

What I do

Building with AI

From automating warehouse reporting to building AI-powered MVPs for startups, the work covers strategy and hands-on development. Running an internal academy to spread AI fluency across an entire organization. The current AI moment looks a lot like open source in the late 1990s: a fundamental shift that rewards the people who build, not the people who wait.

Building teams

From Ramsay Medical Centers in Paris to Holman Logistics in the US, the constant is people: finding them, helping them grow, getting out of their way. At Ramsay, that meant building and leading an IT team through a multi-year digital transformation. At Holman, it means upskilling warehouse staff through the Automation Academy, turning operations teams into builders who can automate their own workflows.

Scaling across borders

Two continents, multiple languages, very different cultures. Lifetria serves clients across the US and EMEA. What works in one place rarely translates directly to another. Having built teams and shipped products in both France and the US, Haïm knows the difference is rarely technical. It is in how decisions get made, how trust gets built, and what "done" means to different people.

Starting from zero

Three companies built from nothing. Green Backup replicated data across three continents. Vudexis brought eye care to underserved communities in France and was profitable within a year. Lifetria helps organizations ship software faster with AI. Each one started with the same question: what would this look like if we built it right?
