About Xavier Duportet, Hello Tomorrow, Deeptech Founders and Eligo Bioscience

First, let’s state I have been a fan of Xavier since I was first invited to speak about hardware startups at his Hello Tomorrow conference in 2016. I was impressed by the production and general vibe. I’ve attended every year since then and it only got better (trivia: on that day, I also remember another man who talked about embracing tech entrepreneurship. He everybody’s hand on his way to the stage where he was speaking before me. Can you guess who that was?).

Now, Xavier Duportet turned out to be more than the founder of what is probably the world’s largest deep tech event. He’s also a synthetic biology PhD with an unusual path:

  • He was born in France, grew a passion for insects (especially ants — he hosts a colony of leaf-cutter ants from Trinidad in his office) that lead him to an internship in a genetics lab at age 12, which ignited his passion for science.

  • Fast forward a few years, after a first startup attempt, he earned his PhD across multiple labs including a stay at MIT which had a profound effect on his mindset and understanding of ecosystems.

  • He came back to France and became a catalyst in the emerging deep tech community by founding in 2011 a non-profit called Hello Tomorrow to bring together scientists, investors and corporates. Today, the event is — afaik — the largest deep tech conference in the world and highlights every year 500 of the top early stage startups.

The next summit will take place in Paris and online in October 2020

  • In 2018, he co-founded Deeptech Founders, a 6-months program that already helped hundreds of global scientists and engineers to accelerate their startup projects.

  • Today, he is the founder of Eligo Bioscience, a biotech startup using CRISPR to create a new class of biotherapeutic agents to selectively intervene on the microbiome. Eligo raised $27.4M from French and US investors including Khosla Ventures and Seventure Partners.

  • Finally, Xavier has been selected as a World Economic Forum Pioneer and Young Global Leader, as well as one of the top innovators under 35 by MIT.


  • In this episode, Xavier shares ideas about science entrepreneurship and the importance of a product-driven mindset.

  • We also discuss how co-founders need be complementary, and combine technology with storytelling and networks to succeed.

  • Finally, he shares his hopes about deep tech’s ability to solve critical problems that digital alone can’t solve, and the importance of accessible role models to support this mission (his historical role model could be called ‘the Edison of biology’ — here is one of his key patents).
