Because a Virus Will Never Stop Us. How does Fatster Team reacts during Covid-19 Pandemic

We are a Team

At Fatster, we are a Team of 12 persons with different positions, different origins, different experiences. We are a Team and it makes us stronger with a very high spirit and motivation. Our mission is to fight the obesity epidemic in the world with the help of a mobile app, nutritionists and AI. The Covid-19 epidemic will not stop this dream we all have.

The Covid-19 affected our operation and we had to adapt the way we work and our product

  • We are fighting against the Covid-19 in the short term with Covidster by connecting individuals with other individuals for Clinical Trial purposes.
  • We are fighting against the Covid-19 in the medium and long term with Fatster to reduce the risk of mortality among the overweight population.
  • Both projects have been submitted to the French government to get funding
  • We adapt fast, act quickly and we try to be as efficient as possible.

The Covid-19 affected our business

  • We save every pennies from our first fund-raising so we have the longest runway
  • We learn from our mentors and business partners
  • We learn from our courses at HEC Challenge+ “how to manage cash flow during a massive crisis”
  • We are lean

To protect ourselves, our colleagues, friends and families, we are working remote

  • From different cities in France
  • From different cities in Thailand
  • We protect ourselves
  • We work from everywhere we possibly can

There is nothing new, nothing magic

  • We are using simple tools like GSuite, Jira, Slack and Zoom as our main tools for remote working
  • We are training our staff and let them learn even more
  • We are doing 40mn sharp meetings
  • We are using Agile methodology

The Covid-19 will eventually disappear, the Team spirit and method of work will remain.

Stay safe, stay home, work hard, play harder 🙂

Fatster helps reduce mortality risks related to Covid-19 by reducing overweight and obesity in the population.

Fatster wishes to contribute to the reduction of mortality risks related to Covid-19 for the French population through significant weight loss. This population will be less at risk compared to the Covid-19 related pandemic but also to future pandemics.

Fatster also wishes to contribute to the reduction of direct and indirect costs related to obesity (a 20% reduction in the number of obese people in France = 10.8 billion Euros saved per year).

Fatster ( has the mission to facilitate the connection of overweight/obese people and help them to lose and maintain their weight over the long term by changing their habits in terms of diet and physical exercise. This with the help of strong motivation, a caring community, health professionals and artificial intelligence.

Obesity is a major risk factor of COVID-19: Professor Jean-François Delfraissy, who heads the scientific council that advises the government on the Covid-19 epidemic, said that no less than 17 million of France’s 67 million citizens were at serious risk of coronavirus due to age, pre-existing disease or obesity. “This virus is terrible, it can affect young people, especially obese young people. Those who are overweight should really be careful,” Delfraissy told France info.

Obesity is a scourge in France: in France nearly one adult in two is overweight, and 20% of those who are obese are overweight. Overweight reduces the life expectancy of French people by 2.3 years. This disease not only reduces life expectancy, it also affects students’ academic performance, labour productivity and undermines economic growth.

Obesity costs France €10 billion a year (5% of its health budget), €54 billion in direct and indirect costs (health and productivity loss) and costs in Europe €59 billion a year (7% of its health budget alone).

In his general policy speech, Edouard Philippe, French PM made the fight against obesity “a national objective” and has the ambition to reduce obesity by 15% by 2023.

“We created Fatster to bring together a community that supports, motivates and helps each other to lose weight. The human side is most important at Fatster, which is why the team did not hesitate to mobilize for the rapid development of Fatster to fight Covid-19 and other pandemics as effectively as possible.”
Fabien Keller & Emmanuel Fauvel, co-founders of Fatster.

“Most people know that being overweight or obese is unhealthy, and if you eat too much that contributes to being overweight […] but just telling people there’s a problem doesn’t solve it.”said Dr. James Krieger, clinical professor of medicine at the University of Washington and executive director of Healthy Food America, an advocacy group.”
