Rennes is the capital of Brittany, the most western part of France. Rennes Metropole (the intercommunal structure) gathers 43 communes that share infrastructure such as the transportation network (bus and metro). It represents 420 000 inhabitants. Rennes has a huge population of students (approximately 60 000) thanks to its renowned Schools of Engineers (INSA, Telecom Bretagne, Epitech, Supinfo, etc.), its Business School and its 2 main Faculties: Rennes 1 (25 k students every year following STEM) and Rennes 2 (20 k students every year in the Social and Human Sciences degree). There is also a School of Fine Arts.  In StartupBlink’s 2019 report, Rennes ranked 6th in France and 222nd globally.

Rennes is renowned for being chosen by many Telecommunication companies such as Orange, Technicolor, Thomson, Motorola and many more, to expand beyond the Parisian area. This technical DNA has made of Rennes the perfect environment for new startups to arise within the last 10 years, going far beyond the telecommunications expertise. These young companies work on image & sound, networks, on-demand services, domotics, health, mobile, and many other areas.

Rennes is also well-known for being the home of Ubisoft, one of the top 3 video games companies worldwide (the editor of Assassin’s Creed, Just Dance, Rayman, etc.)

It is part of the French Tech movement and has is among the first regional metropoles to have received the French Tech Label in 2014.

Most successful startups in Rennes

Rennes is historically a territory of technical excellence and many companies have world-class expertise in sound, image, and networks.

Speaking of networks, in the 70s Rennes invented the Internet’s ancestor, the Minitel: a Videotex online service accessible through landlines, which was one of the most successful pre-Internet online services (with services like online shopping, phone directory, mailbox, and even real-time chat).

JPEG: In 1988, a group of international experts worked on compressing algorithms to transfer pictures more quickly across networks. The algorithm that is at the core of JPG compression comes from an engineer in Rennes, working in the most famous R&D center: CCETT. Engineers from Rennes also had a major role in the MP3 and MPEG compression algorithms.

Rennes has evolved its core skills to cybersecurity, image & sound, e-health, gaming, domotics, platforms and augmented reality.

Advantages for startups in Rennes

Rennes is a great place to start a startup and has always been a territory turned towards innovation and experimentation. There is a solid network of key actors that build a good startup ecosystem:

Accelerate it

Many acceleration programs co-exist to deliver the best support at every stage of the startup life. La School (, Le Booster (, Start Me Up (https://), MVCube (, OFF7 (, RegionsJob Start (, KITA (

Incubate it

After the acceleration phase, startups and young companies can settle in one of the many incubators in Rennes: Telecom Bretagne, La Palmeraie or the metropolitan public incubators Gallium & Germanium.

Kickstart it!

On top of the national crowdfunding platforms, Brittany has set up 2 regional platforms to help startups launch their prototypes: Gwenneg ( and Kengo (


Rennes was one of the pioneers of the coworking trend back in 2010 with the opening of La Cantine numérique rennaise and since then more than 10 coworking spaces have emerged to serve the expanding demand of nomad workers: La Cordée (, Happy Hours (, Le Loft (, Le Lavoir (, Ubiplex (, L’atelier 10i (, Thabor Coworking (, Lab61 (, Espace BZH ( and La French Tech Rennes St Malo (

Host it

It’s quite easy and inexpensive to find a place for your first years of activity and if you have special needs (like for instance a workshop or a production line or a warehouse) you can use BreizhLab (, a network of industrial companies gathered to make the extra space they have available to startups, be it in Brittany or worldwide.


Rennes has its own airport and is 2h15 away from Paris by train. In 2018, thanks to heavy investments in the High-Speed Line, Rennes will be at 1h30 from Paris, opening new possibilities for entrepreneurs to move around and attracting entrepreneurs away from the saturated Parisian environment.


Rennes has plenty of formal or informal networks to get help from Yao Bretagne (, Cercle des Jeunes Dirigeants (, CCRE35 (, Dynamic35 (, Réseau Entreprendre (, Rennes Initiatives (


Rennes regularly appears in the top 10 cities where people want to live for a better work/life balance. It is located in the center of Brittany, at 50 mins from the North coast (St Malo) and 50 mins from the South coast (Golfe du Morbihan).

Finding talent

Last but not least, talent is rather easy to find among the 60k students in town. It is uncommon to hear that a startup can’t find the talents and profiles it is looking for.

Disadvantages for startups in Rennes

Like in many other regions, there are not enough seed investing mechanisms and business angels, which forces founders to rely on their own resources or to launch crowdfunding campaigns to kickstart their activities. They also tend to apply to many contests, grants or helping programs to get the few thousand euros that will take them to the next step. This dilutes the effort they should make to find their market. Basically, instead of being focused on finding clients, startups need to spend time on administrative tasks to get what it takes to survive the first year. With more seed investment (or even pre-seed) some projects could really be accelerated and maybe we would witness more fast-growing startups than we currently do.

Then there is the aspiration of Paris. Rennes, of course, is not the only city to suffer from centralization. But the concentration of the business resources in Paris attracts founders to the capital. This also dilutes the founders’ energy with a lot of back and forth trips to Paris.

If startups have to travel abroad, the Rennes airport does not serve a lot of national or international destinations. It would probably take you a day to go to Berlin from Rennes, thus limiting the reach of many projects, or adding a consequent travel budget.
