Mobius

What Mobius does

Mobius (branded möbius) is the public transit bus network operated by STGA (Société des Transports du Grand Angoulême), serving the GrandAngoulême agglomeration in southwestern France under a public service delegation contract with the local metropolitan authority. The network spans 660 km of bus lines and 1,400+ bus stops, comprising 10 main lines, 6 relay lines, 2 BHNS high-service-level lines (A and B), shuttle, express, and proximity routes, plus 28 school lines and 2 StudiBUS lines for boarding students. It is complemented by Transport À la Demande (TAD) on-demand service covering 30+ municipalities with light vehicles, an adapted variant for reduced-mobility passengers, 4 Park & Ride facilities, 3 secure bike parks, 16 bike shelters, and a bike rental program (classic, electric-assist, folding).

The technology stack is conventional public-transport IT: real-time GPS tracking surfaced via the maStgamobile mobile app, QR-code and contactless smart card (mobili'carte) ticketing, an e-boutique web portal for account and subscription management, and the VocaBus accessibility app for vocal bus-arrival announcements. Booking and reservation for on-demand transport and bike rental are outsourced to third-party platforms Padam.io and Locvelo respectively, with Google Maps integration for journey planning and SNCF for intermodal rail correspondence.

The business model is a regulated public service operation. Revenue is generated from farebox sales (single tickets, multi-journey packs, 24-hour passes), tiered monthly and annual subscriptions segmented by age (under-18, 18–25, 26+), solidarity fares for low-income and disabled riders (50–75% reduction), free passes for non-taxable seniors 65+, bike rental subscriptions (€11–€165), corporate Mobility Plan (PDM) programs, and P+R parking fees. Customer segments span urban commuters, students, seniors, low-income residents, reduced-mobility passengers, and new residents. Distribution combines the Agence Mobilité physical hub, ~50 partner retail outlets, on-board sales, DAT vending machines, the e-boutique, and three mobile apps. The operation is financially underwritten by GrandAngoulême Agglomération via the versement mobilité mobility levy, EU co-financing, and fare revenue, with no venture or growth capital involved.

Scale indicators14 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Keolis: Keolis is the SNCF subsidiary operating transit networks across France and globally; it operates integrated bus, tram, and multimodal MaaS offerings for French agglomerations with comparable business models to Mobius, just at much larger scale.
• Transdev: Transdev is a major French-headquartered multinational public transport operator and is already a contracted school-transport partner (Transdev Citram) for the Mobius network; it provides direct comparable scale across fixed-route bus, on-demand, and multimodal mobility services.
• RATP Dev: RATP Dev operates urban transit systems (bus, tram, paratransit) in France and internationally under public service contracts; it is a directly comparable French transit operator with multimodal offerings and integrated ticketing approaches.
• JCDecaux: JCDecaux operates large-scale bike-share systems (e.g., Vélib' in Paris) and is a relevant incumbent in urban mobility infrastructure with operational models combining bike rental, secure parking, and advertising revenue - comparable to Mobius's bike rental and Parcs Vélos.
• TCL - Transports en Commun Lyonnais: TCL operates the public transit network for the Lyon metropolitan area - much larger than Mobius but a direct peer in business model (multimodal urban transit with bus, on-demand, bikes, app) and in serving a French agglomération under public service contract.

Others

• SNCF: SNCF is the strategic rail-integration partner with which Mobius offers correspondence tickets and intermodal fare products; it represents the broader public transport ecosystem Mobius plugs into for end-to-end journey planning.
• Google Maps (Google): Google Maps is the integration partner providing real-time transit data display for Mobius's journey planning; it represents the broader mapping and MaaS data ecosystem that transit operators depend on for rider acquisition.

Direct peers

• TBM (Transports Bordeaux Métropole): TBM is the public bus and multimodal transit network for the Bordeaux metropolitan area in France, providing fixed-route buses, on-demand, park-and-ride, and digital ticketing - functionally the closest peer to Mobius at a larger scale within a French agglomeration.
• Naolib (ex-TAN Nantes): Naolib operates the public transit and bike-share network for the Nantes metropolitan area, including bus, on-demand, bike rental, and P+R under a unified brand - structurally similar to Mobius's integrated multimodal offering in a mid-sized French agglomération.

Emerging players

• Padam.io: Padam.io is the technology partner that powers Mobius's Transport À la Demande (on-demand) booking platform; it serves as a comparable emerging player in on-demand transit software and competes for the same TAD contracts across France.
