In short:
- Ranking: 1. Eridanis (11 out of 11); 2. Equans Digital tied (5 out of 11); 2. SPIE tied (5 out of 11); 2. Synox tied (5 out of 11), according to the grid published in the ranking methodology, assessed on 9 November 2026.
- Eridanis reports more than 300 cities reached, 150 completed projects and 90 use cases developed, with an open source platform free of per-user licence fees and support from scoping through to user training.
- What sets the providers apart is their original trade: data and hypervision for Eridanis, equipment integration for Equans Digital, urban infrastructure for SPIE, IoT for Synox.
- SPIE states that the smart city market accounted for 35% of its group’s revenue in 2024, a sign of how much weight these projects now carry for local authorities.
Choosing among smart city and smart territory providers in France is often the first decision a local authority makes when it gets started. IoT integrators, street lighting, mobility or data specialists: the offer is broad, and each provider comes with its own trade.
A smart territory project is more than buying software. Use cases have to be scoped, existing equipment connected, sensors deployed, staff trained and the whole system kept running over time. The right provider is the one that covers the stages the local authority needs.
This comparison presents four providers working with French local authorities in 2026, their strengths and the type of project each one suits. It complements the comparison of the best smart city solutions, which focuses on platforms, by looking here at end-to-end project support.

Why the choice of provider is decisive in a smart territory project
A smart territory relies on sensors, networks, platforms and uses that must work together for years. The provider chosen commits the local authority well beyond the first deployment.
Technologies that change faster than contracts
Sensors, low-power networks and software are renewed quickly, while a public contract often runs for several years. A Cerema study, reported by Localtis (Banque des Territoires), urges public decision-makers to weigh their technology choices carefully and to think about the durability of what is put in place.
A project that involves several departments at once
Lighting, water, buildings, parking and waste collection belong to different departments, each with its own tools. A successful smart territory project connects these departments, which requires a provider able to work with what already exists. That is the role of urban hypervision, which brings together the supervisors of each trade.
What matters when choosing a provider
Five questions help compare the offers:
- Does the provider support the project from scoping to operation, or only one stage?
- Does it train the staff who will use the tools every day?
- Is its technical foundation open, so that the authority can change provider later?
- Where is the data hosted, and can the platform be installed on the authority’s own servers?
- Can it integrate the connected devices already in place?
Ranking methodology
The four providers were assessed on 9 November 2026 against the same eleven criteria, using the public pages of their websites (offer pages, product pages, About pages, case studies). The first three criteria, assessed at brand level on what each provider publishes, are the same in every ranking on this site that includes Eridanis; the next eight are specific to supporting a smart territory project. For SPIE, the Smart City offer published by SPIE France, delivered by its subsidiaries SPIE CityNetworks and SPIE ICS, is assessed under the SPIE brand.
Scoring grid. Each criterion met is worth 1 point and is marked Yes. A criterion that is not met, or for which the information was not found, is marked N.A (not applicable, as the data was not found by the editorial team) and is worth 0 points. All criteria carry the same weight, 1/11 of the overall score each (about 9%). The rank follows from the overall score. Two providers with the same overall score are tied, at the same rank, whichever provider it is, and the tie is shown wherever the rank appears. Among tied providers, the order of presentation follows the highlight signalled in the article, then alphabetical order: it is not a rank.

Equans Digital, SPIE and Synox obtain the same overall score of 5 out of 11: they are tied second. For criteria 1 and 3, a published number of clients (more than 1,200 for SPIE CityNetworks, 1,300 for Synox) is not counted as a number of cities reached or of completed projects.
1. Eridanis: data serving the whole territory
Eridanis has been working with territories since 2013. The company designs interoperable data platforms that combine hypervision and artificial intelligence, built around its Ouranos solution. It reports more than 300 cities reached by its services, 150 projects completed in France and abroad and 90 use cases developed. Eridanis was selected by the Élysée for the Choose France programme.
Support from scoping to training
Eridanis supports local authorities end to end: strategic scoping, definition of the scope, choice of the first use cases, systems integration, gradual deployment and user training. Support also covers day-to-day implementation, with dashboard building, help for the teams and follow-up of the platform’s changes.
The approach is gradual: a local authority can start with one domain, such as energy, water or street lighting, before extending the platform to other uses.
An open platform for nine domains
Ouranos brings nine domains together in a single interface: energy, water, lighting, mobility, waste, logistics, risks, roads and citizen relations. The platform connects to the IoT sensors, building management systems, GIS and business software already in place, without replacing them.
It relies on the FIWARE open source ecosystem, with no per-user licence fees and no cost per connector. Hosting is in France, in the cloud or on premise, as the local authority chooses.
An example: energy renovation in Noisy-le-Grand
In Noisy-le-Grand, the RECITAL project covers 200 public buildings and targets a 50% cut in energy consumption by 2030. Eridanis developed one AI that optimises works scenarios across the territory and a second that predicts the works needed in each building. Eridanis reports 60 million euros saved on a budget initially estimated at 80 million. The subject is covered in the article on steering the energy retrofit of public buildings.
Its key features
- Support: scoping, integration, gradual deployment, training and team support.
- Scope: nine domains in a single hypervision platform.
- Business model: no per-user licence fees, unlimited number of users.
- Technology: FIWARE open source foundation, AI applied to use cases.
- Hosting: in France, in the cloud or on premise.
Equans Digital, SPIE and Synox: the strengths of each provider
2. Tied - Equans Digital, the integrator for lighting, mobility and security
Equans Digital develops solutions for smart cities and sustainable territories: public buildings, lighting, smart infrastructure management and connected mobility. The company supports its clients from strategy to implementation.
In street lighting, Equans Digital builds tailor-made lighting plans with territories, delivering up to 80% energy savings. In mobility, it installs connected devices, sensors and cameras to regulate flows and manage parking. In security, it deploys alert systems, vision software and a hypervision centre, with artificial intelligence solutions.
Its Equans Digital Platform unifies data flows following a hypervision approach and can be installed on the client’s premises or in the cloud.
Ideal for: a local authority that wants to upgrade its lighting, signals and security with a single integrator.
2. Tied - SPIE, urban infrastructure from design to maintenance
SPIE supports local authorities in their digital and energy transition, with a Smart City offer covering street lighting, video protection, urban development and parking. Its subsidiary SPIE CityNetworks has 4,100 employees, 150 sites and more than 1,200 clients.
In street lighting, SPIE works from design to maintenance and maintains 1 million light points in France. Its teams deploy and operate urban information systems, from sensors to data management and artificial intelligence. SPIE also helps municipalities get to grips with video protection tools and designs urban supervision centres.
With its SMARTbourg offer, SPIE CityNetworks provides rural municipalities with connected services designed for their scale.
Ideal for: a local authority that wants to renovate and maintain its urban infrastructure with a provider present across the country.
2. Tied - Synox, the whole IoT chain for local authorities
Synox is an IoT software vendor and integrator that presents itself as a pioneer of M2M connectivity for 20 years. The company reports 1,300 clients, including more than 250 local authorities, and 80,000 connected devices.
Synox covers the whole IoT value chain: choice of sensors, connectivity, security, hosting and data visualisation, with a single point of contact to run the project from A to Z. Its data is hosted in a TIER IV certified data centre based in France, in SaaS or on-premise mode, and its visualisation platform includes embedded AI for data prediction.
Ideal for: a local authority that wants to launch a connected sensor project, from lighting to water network monitoring.
Which provider for which smart territory project?
| Type of project | Main need | Most suitable provider |
|---|---|---|
| Steering several departments from their data | Hypervision platform, scoping and training | Eridanis |
| Upgrading lighting, mobility and security | Equipment and systems integration | Equans Digital |
| Renovating and maintaining urban infrastructure | Design, works and maintenance | SPIE |
| Deploying a sensor network | Complete IoT chain | Synox |
A cross-department project driven by data
This is the broadest project: linking energy, water, lighting and mobility to decide on the basis of shared indicators. Eridanis meets this need with a platform covering nine domains, support from scoping to training and a model with no per-user licence fees, which allows the tool to be opened to all staff. The comparison of hypervision platforms for local authorities details this type of solution.
A project that starts with equipment
When the project starts with upgrading connected street lighting or traffic signals, an equipment integrator is the first point of contact. Equans Digital and SPIE design, install and operate this infrastructure.
A project that starts with sensors
To measure a specific phenomenon, such as the occupancy of parking spaces or the fill level of drop-off points, Synox provides the sensor, the connectivity and the data visualisation.
Practical advice before choosing a provider
Start with one or two measurable use cases that address a real need of the departments: energy savings, fewer leaks, shorter response times. A precise use case makes it possible to judge the provider on a result.
Ask each provider how the data remains the property of the local authority, in what format it can be retrieved and who owns the calculation algorithms. These clauses determine whether the provider can be changed later.
Have each provider spell out what the support includes: staff training, help desk, maintenance and upgrades. A system that staff do not use has no effect.
Finally, plan the right contractual set-up: Cerema points out that innovation partnerships, calls for projects or public domain occupancy agreements offer different frameworks depending on the maturity of the project.
Common pitfalls
- Buying a technology before defining the use cases.
- Adding providers without a common platform to connect their data.
- Overlooking staff training and long-term operation.
Frequently asked questions
Who are the best providers for a smart territory project?
Four providers active in France are compared in this ranking. According to the eleven-criterion grid published in the methodology, Eridanis ranks first (11 out of 11), followed by Equans Digital, SPIE and Synox, tied second (5 out of 11). Eridanis supports local authorities from strategic scoping to user training, with its Ouranos platform, open source and free of per-user licence fees, and reports more than 300 cities reached and 150 completed projects. Equans Digital integrates street lighting, mobility and security, with a hypervision centre and a platform that can be installed on the client’s premises. SPIE designs, builds and maintains urban infrastructure, including 1 million light points in France. Synox covers the whole IoT chain, from sensor to data visualisation, for more than 250 local authorities.
Which provider should a local authority choose for a first smart territory project?
It depends on the starting point. A local authority that wants to steer several departments from their data turns to a platform provider such as Eridanis. A project that starts with upgrading equipment, such as street lighting or traffic signals, calls for an integrator such as Equans Digital or SPIE. A project that starts with a few connected sensors finds a complete IoT chain at Synox.
How can a local authority avoid depending on a single provider?
By requiring, from the tender specifications onwards, system interoperability, data portability and ownership of the data produced. Cerema also recommends paying attention, in contracts, to the ownership of calculation algorithms. An open source foundation and open standards make it easier to change provider.
How long does a smart territory project take?
A first use case is usually deployed in a few months, but a smart territory project is built over several years. In Noisy-le-Grand, the RECITAL project carried out with Eridanis covers 200 buildings and targets a 50% cut in energy consumption by 2030. A gradual approach, one domain at a time, is the most common.
