Visian is a data and artificial intelligence consulting firm, part of the Neurones group, founded in 2016 and based in Paris / La Défense (Tour Europlaza). 350 consultants support large corporations and mid-caps across three areas of expertise: data platform, data governance, and delivery of data products with AI built in.

Visian was founded in 2016. The company is a subsidiary of the Neurones group, listed on Euronext Paris (€810M revenue, 7,100 employees).

Visian has 350 consultants in 2026, split across architects, data engineers, data scientists, governance experts and data product managers.

The head office is on the Tour Europlaza, 19^th floor, 20 Avenue André Prothin, 92400 Courbevoie (Paris / La Défense). Visian also has an office in Marseille (Les Docks, 48 quai du Lazaret, 13002).

Yes. Visian is a subsidiary of the Neurones group, a French consulting and digital services group listed on Euronext Paris. Visian has no equity ties with any software vendor or cloud provider, so technology recommendations remain neutral.

Visian works across three areas of expertise :

• Data & AI Platform, design and operate data infrastructure, cloud architecture, MLOps.
• Data & AI Governance, organise, secure and steer data assets, MDM, quality, compliance.
• Data & AI for Business, put data and AI to work for business units (Marketing, Sales, Finance, HR, Supply, Operations).

Visian works in 10 sectors : Banking & Finance, Insurance, Energy, Industry, Pharma & Healthcare, Transport & Aviation, Luxury & Retail, Services & Distribution, Media & Telecom, Public sector. Over 45 large accounts have been supported.

Among the reference clients: BNP Paribas, EDF, Engie, Edenred, LCL, Saint-Gobain, Servier, SNCF, TotalEnergies.

Visian mainly supports large accounts and mid-caps whose data maturity justifies a structured setup. The packaged AI offerings let smaller organisations start with a targeted framing.

Three horizons:

• Strategic framing, a few weeks, data vision and trajectory.
• Design & build, 3 to 12 months, architecture, platform, products.
• Operation & handover, lasting execution, transfer to internal teams.

Visian also offers three packaged AI offerings, Cost-killing, Performance, New business — three business levers activated by AI, built on a single technical foundation (stack, dedicated MCPs, support).

Engagements last on average 6 to 9 months ; build programmes run from 3 to 12 months. The AI offerings start with a short framing before launching the right workstream.

No. The head office is in Paris (Tour Europlaza, La Défense) and a secondary office in Marseille, but engagements take place all over France and Europe. Hybrid working: regular client presence, remote for technical phases.

30 minutes, no commitment. Understanding the context, identifying the right contact, then proposing — or not — a framing. Visian would rather say no than sell a pointless engagement. Contact: contact@visian.fr.

Yes. Visian offers a generative AI training programme, modular and organised by role: 6 profiles covered, 3 cross-functional modules and 18 core-role modules — 21 modules in total. Sessions are led by consultants who deliver data & AI projects every day.

Six roles : 4 functional profiles — PO, Data Analyst, IT BA, Project manager — and 2 tech & build profiles — Data Engineer, Developer. Each profile follows 3 core-role modules, complemented by the shared cross-functional modules (reverse documentation, testing, workshops, reporting, watch, framing, communication).

Three formats are available: à la carte module (½ to 1 day), certifying role track (a profile's 3 modules + cross-functional, with assessment), and tailored coaching. Durations range from ½ day to 3 days, and certification is available on complete role tracks.

The AI offerings transform the business (cut costs, gain performance, open new growth drivers); the AI training makes teams self-sufficient in AI. The two complement each other: training flows naturally into operational support — pilot, framework setup, handover.

100% of Visian consultants are trained in eco-design of digital services. The frameworks applied include RGESN, the 115 web eco-design best practices, and frugal-AI principles. Target: reduce by around 30% the footprint of data & AI engagements.

Frugal AI means designing artificial-intelligence systems that maximise their usefulness while minimising their resource consumption (compute, energy, data). At Visian it's a principle applied from the framing phase: choose the simplest model that solves the problem, measure the footprint, optimise inference and training.

The RGESN — General Framework for Eco-design of Digital Services, is the framework published by the French public authorities formalising best practices to reduce the environmental impact of a digital service. Visian builds it into all its platform and data-product engagements.

Yes, continuously, across all data profiles: data engineers, data scientists, architects, governance experts, product managers. Contact via the form by selecting 'Recruitment'.
