Haïm Dimer speaking

Haïm's journey spans continents and industries. From early work in open source software and internet technologies to founding startups in both the United States 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.

What I do

Building with AI

At Lifetria, helping companies build with AI and no-code tools. At Holman, leading the Automation Academy to bring AI fluency across the organization. The focus stays on what ships and what helps.

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.

Scaling across borders

Three continents, multiple languages, very different cultures. Lifetria serves clients across the US and EMEA. What works in one place rarely translates directly to another.

Starting from zero

Lifetria, Vudexis, Green Backup. Three companies from scratch, each one teaching something different about product, timing, and the gap between a good idea and a working business.

Documentary work

Thought leadership
