A sample exchange

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. Most recently, as Director of IT for a logistics company with 20 warehouses, he rolled out AI and automation and built an internal academy that turned operations staff into builders. Today he runs two companies: Lifetria, an AI-native software studio, and STC, an AI training, coaching and strategy firm.

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 his current work. Lifetria builds software where AI writes most of the code and senior engineers conduct. STC teaches teams to do the same thing themselves, so companies depend less on bloated enterprise software and more on their own people.

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

Teaching people to build

Haïm has been teaching since his early twenties: free Saturday classes while he was still a student, then a classroom in Florida explaining Linux. The subject has changed. The best part hasn't: the moment someone who "isn't technical" builds their first tool and realizes they can do it again. He saw it with warehouse teams who now automate their own reporting, and he sees it today with every group he works with.

Building with AI

Lifetria is an AI-native software studio: AI does 90% of the work, and senior engineers act as conductors. Strategy, implementation and integration into the systems you already run. Haïm builds his own products this way too: Juno (opens in new tab), a personal CRM that remembers every relationship. Dictate a note from your phone and AI files it under the right person and project. 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.

From the command line to the boardroom

Most AI advice comes from people who have never run a server. Haïm taught Linux at 22, ran 340 servers across three continents at Akamai, then became CTO and later CEO of a $125M healthcare group with 1,700 employees. He understands the technology down to the wire and the business up to the board, in the US and in Europe.

Starting from zero

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. STC helps people and teams build with AI. Each one started with the same question: what would this look like if we built it right?
