BPGO helps finance the innovation of the startup SOCIAL CRUNCH

Founded in 2019 by Fabien Keller and Emmanuel Fauvel, the startup SOCIAL CRUNCH (Fouesnant, Brittany) develops the Fatster mobile application facilitating weight loss thanks to a caring community, dieticians and an artificial intelligence. Fatster proposes to its members to find their ideal weight loss partner sharing the same characteristics and weight loss ambitions.

Within a few months, the application registers several thousand users and the counter of kilos lost and calories saved flies away.

At the end of 2019, the company completed its first “pre-seed” fund raising of 103,000 euros and is supported strategically and financially by the Public Investment Bank (BPI) and the Quimper Technopole. This financing helps the HealthTech in its developments with a focus on “preventive health” as well as in its technological developments and proves the appetence of its solution to a young, overweight and very digital target

After several hundred exchanges with its first users, the company pushes back the limits of its first version by giving way to Fatster version 2. All previous technological developments are abandoned. The Fatster application gets a new look by integrating a last generation cloud technology and builds all its code with the same technology used and deployed by Facebook: React Native. Its B2B solution for nutrition professionals called NUTRIMIS is also born.

The western company then met with the Banque Populaire Grand Ouest (BPGO) as part of an innovation financing scheme allowing the startup to acquire maturity in its B2C and B2B technologies and their commercial deployment. The agreement was signed at the end of May 2020. The funds granted are co-financed by the bank and the European Investment Fund.

The start-up, based in Fouesnant to develop the French market, also has offices in Bangkok (Thailand) to develop the company in South East Asia. It wants to have a sustainable and social impact in the Finistère region (29) with the first key recruitments in 2020.

Overweight and obesity are aggravating factors with regard to COVID-19 and French have gained an average of 2.5 kilos during confinement according to IFOP. Fatster is there to help them.

The founders of SOCIAL CRUNCH would like to thank the BPGO for its trust and wish to start a strong long-term relationship with the bank.

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 (www.fatster.app) 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.

During coronavirus time, get active, eat better and lose weight at home

It’s going to get harder and harder to do sports in the next few days with the Coronavirus.

Indeed the infrastructures and sports clubs will probably close in the coming weeks.

Don’t worry, Fatster is here to help you burn calories despite the restrictions caused by the virus. Here are three physical activities to do at home:

Image result for fentes

Lunges, the perfect exercise for cardio and strengthening:

If you don’t know this exercise you will work your abs and thighs at first. Indeed to master this exercise it takes time and you will do each lunge quite slowly. Don’t panic, this exercise is already very useful. It will make you work your thighs, buttocks and abs.

Image result for squat

Squats, a difficult exercise:

This exercise is complicated especially because it is difficult to have the perfect position to do squats. Be very careful on this point, you will hurt your back very badly. The simplest is to start with a chair at the beginning to have a support and an easier position to hold.


Image result for burpees

Burpees, one of the best ways to lose those extra pounds:

Indeed burpees make you work your arms, abs, thighs, buttocks and especially your cardio! Don’t be surprised if you suffer during your first sessions, start with small sequences. If you do them regularly you will quickly see the results.


The board: lose weight and gain posture.

Start like you’re going to do push-ups with your hands under your shoulders. Stand on your toes and squeeze your abs and buttocks together to form a straight line. Try to tuck your belly button in and make sure your back is straight. Start by holding the position for 20 seconds and increase as you work out.

The dips: making the arms work

Place your hands on the edge of a chair or sofa and your legs in front of you. Lower your body to the floor (be careful not to block your elbows), then raise your body up with the strength of your arms. Do three sessions of 10 reps, with a break in between

Don’t forget to post your physical activities at home on Fatster!

The honest truth about weight loss progress

You will need to make radical changes in your habits to maintain long-term weight loss. We have 66 days to do this together with the help of Fatster and the community because a habit is actually lost in 66 days (see How Long Does it Actually Take to Form a New Habit?).

Research from the US NWCR (National Weight Control Registry) shows that the following habits are effective for people who have lost a lot of weight without regaining it:

  • 78% of people eat breakfast every day.
  • 62% of people watch less than 10 hours of television per week.
  • 90% of people exercise, on average, about one hour a day.

Your habits will largely determine the success of your weight loss over the long term.

To develop a healthy eating habit, we recommend this simple approach:

  • Choose a specific habit that you wish to change. For example, “stop drinking soda”.
  • Start with a very small step. Replace a soda (coke, sprite, etc.) with water this week. That’s all you have to do.
  • Focus on the journey. Commit to the process, not the goal. Take small daily steps and you’ll turn any bad habit into a good habit.
  • Track your progress using Fatster App. Write down the steps you take each day. It will take you 30 seconds. The rewards will be worth it.

That’s why we offer Fatster challenges that will help you with nutrition (eating healthier), activity (3 hours of exercise every week) and weight maintenance.

Losing weight is a marathon, not a sprint. So take it easy. Focus on one habit at a time.
Above all, believe in yourself and your ability to take charge of your health and your future.
