NVIDIA invests in Doctolib, Open Source and Value Migration

Two days ago Doctolib announced that NVIDIA is investing in the company:

Paris, 13 October 2026 - Doctolib, Europe’s leading healthtech company, is building its AI solutions and models in Europe, for health professionals and patients. Doctolib is advancing this work with a planned minority investment from NVIDIA. The investment will support Doctolib’s continued acceleration in AI…

Strengthening Doctolib’s sovereign AI models in healthcare 

Doctolib is developing its own AI models to the highest standard of medical accuracy. In the coming months, Doctolib will accelerate the development of AI models based on open models (open-weight and open-source) and invest even more in its European infrastructure. Doctolib hosts all health data in the European Union and the UK, in line with each country’s hosting requirements and under its sole control. The same applies to its AI models.

NVIDIA arguably holds 90% of AI training and 74% of AI inference market shares, which makes it the world’s most valuable publicly traded company in the world. They have the fastest and most powerful general-use AI chips, which is what you need if you want to develop the fastest and most powerful general-use AI models (aka AGI). But as the AI market evolves and smaller, use-case specific models become more common, so does the competition from cheaper, application-specific chips increase.

Investing in vertical model-building companies such as Doctolib, subsidising them with the NVIDIA stack, all the while making them dependent on the technology, is one way to ensure NVIDIA chips get used at the company remains at the top. Microsoft did the same thing when they invested in OpenAI.

The risk of eventually becoming dependent on NVIDIA’s infrastructure is a risk worth taking for Doctolib, if accessing the best GPUs now - in times when they are both expensive and unavailable - is going to help the company grow their market share and win talent. Indeed, if they miss the current window, being independent later won’t matter much.

To differentiate them further, Doctolib is planning to open-source their models. Commoditise your complements is a business strategy that everyone working in tech should read about. By open-sourcing models, Doctolib wants to kill the "proprietary AI model moat" of other digital health companies. The result will be an increased demand of their own, now unique, product.

Furthermore, Doctolib pushing the medical industry into open-source / open-weight models is even greater news for NVIDIA, which stands to benefit greatly from an entire market of undifferentiated software needing their very much differentiated hardware.
