Where the G7 network still wins
G7's strength is liquidity and brand. A century-plus of operation under Groupe Rousselet, roughly 10,000 affiliated Paris drivers, a large green fleet, and deep corporate and government contracts make it the default taxi central in Paris. For an individual driver, affiliating with G7 is a rational way to access that demand. But G7 is a closed in-house central, not a platform another operator can license or white-label — the technology is proprietary and internal, there is no operator self-onboarding or public API tier, and the booking carries G7's brand, not the operator's.
