Fluctuo has just won the European edition of the FIA Smart Cities Global Start-up Contest Season 4. 

Q. Can you tell us the story behind fluctuo and its founding team?

Fluctuo was created in Paris in 2019, but the origins of the company go back to 2017. At that time, Pierrick (fluctuo CTO) put an interactive map online which catalogued free-floating bicycles deployed by Chinese companies (ofo, Mobike) in large cities around the world. In the succeeding months, he added the first electric scooter services (Bird, Lime).

Contacted by independent developers and companies (who wanted to integrate these new mobility offers into their sites and their apps), Pierrick developed an API (Application Programming Interface) which gives real-time access to the data on these services. 

On my side, after having held the position of Marketing Director at Smovengo (which operates Vélib’, the Parisian bike share service), I was convinced of the incredible potential of shared mobility. My meeting with Pierrick at the start of 2019 accelerated things further. I introduced him to Aymeric and Jean-Marc with whom I had already been part of a team on earlier projects. We decided to pool our expertise to create fluctuo and to make it the leader of “Mobility Intelligence”.

Q. What is the problem that you've identified and you are trying to solve with fluctuo?

The urban mobility sector had for a long time been dominated by the public sector (cities, major conurbations, central government), which decided on and financed the operation of mass transport services (bus, underground, train, etc.).  But over the last eight years, private sector companies have been creating a new generation of on-demand transport services (ride-hailing services, car sharing, carpooling, free-floating).

Although this proliferation of initiatives offers new transport options to users, it also makes the market harder to navigate. This is where fluctuo steps in! We gather, aggregate and analyse data from more than 110 shared mobility services from around the world (bicycles, scooters, mopeds, cars). Our customers can use this reliable and exhaustive information to make strategic decisions.

Q. How is fluctuo going to impact cities in the future?

To build the city of tomorrow, you need to be able to observe and analyse how people get around. However, these means of transport can evolve very quickly.

This can be because new services are offered by companies and massively adopted by city-dwellers: for example, no one got around on an electric scooter even as recently as three years ago.

Or, because events cause us to rethink established practice: the COVID-19 crisis is the ultimate example of this. It will impact means of transport for the long term in all the major urban areas around the world, making individual means of transport more attractive to the detriment of public transport. The risk is that we witness an explosion of the number of individual cars on the road, with all the consequences that this entails for urban congestion and atmospheric pollution.

To prevent such a situation arising, we have to encourage the emergence and development of shared micro-mobility services, worldwide. This is the mission of fluctuo.

Q. How many partners are you working with and what is their feedback so far?

Fluctuo currently has around 20 customers. Shared mobility operators (such as the Swedish VOI, the German Tier or the Franco-Dutch Dott companies); car manufacturers (such as Renault); public transport operators (RATP which operates bus and subway in Paris, the SNCF, French railway company) but also urban planning agencies and consulting firms.

Their uses are varied. Shared mobility operators use our solutions to identify countries or cities where they could launch their service. An operator like SNCF is able to analyse the flow of journeys around its stations to offer improved access to users of shared vehicles. An urban planning agency can study the journeys within the same urban area so that it can propose appropriate planning measures (car parks, cycle paths, etc.).

Q. You’ve just won the European Edition of the FIA Smart Cities Global Start-Up Contest Season 4. What is next for fluctuo?

We are very proud to be the winners of the FIA Smart Cities 2020 Contest: it strengthens our ambition to make fluctuo the European leader of data on shared mobility services.

To accelerate our development, we plan on recruiting several staff members shortly, notably developers and data scientists. We also plan to raise some funds before the end of 2020.

The COVID-19 crisis has obviously affected us, but we think that the end of the lockdown will lead to a growth in the use of shared mobility services (particularly bicycles and scooters). We are strongly optimistic about the future of this market.


Fluctuo is a start-up specialised in the collection, processing and analysis of data from shared mobility services (bikes, scooters, mopeds and cars). Fluctuo aggregates the data of over 110+ operators in 400 cities and makes this data available to its customers via a real-time API. Fluctuo also offers a business intelligence tool to precisely understand the supply and usage of shared mobility services in more than 40 European cities.
