The Subscription City: Why Urban Innovation Is Starting to Look Like SaaS

From Grants to Recurring Revenue

For decades, public innovation in France followed a familiar rhythm: a call for projects, a lump-sum grant, a report, and, often, silence until the next funding cycle. That model, critics argue, rewards short-term pilots over long-term transformation. It is this gap that has pushed some private-backed initiatives to experiment with a different economic architecture: the subscription.

Ville de Demain, a program dedicated to accelerating the digital and environmental transition of French cities and startups, has structured part of its financing around recurring commitments rather than one-off disbursements. Cities and companies enrolled in the program pay a continuing fee, modest compared to traditional consulting contracts, in exchange for sustained access to expertise, shared infrastructure, and iterative support rather than a single injection of capital.

Why Recurrence Changes Incentives

The logic is not purely financial. Subscription-based models change the incentive structure on both sides. A municipality that commits to a multi-year relationship, rather than a single grant application, is pushed to plan transformation as a continuous process rather than a discrete project with a start and end date. On the provider side, recurring revenue forces accountability: value must be demonstrated repeatedly, not just once at the moment of funding approval.

Nicolas Régnier, who leads the program, has framed this as a deliberate response to a structural weakness in how public innovation has traditionally been financed. Where grants create a cliff, funding, then nothing, subscriptions create a slope, in which support scales with proven adoption and measurable outcomes. That, in theory, discourages “innovation theater”: flashy pilots designed to satisfy funders rather than solve real municipal problems.

The Role of Private Capital

None of this would function without patient capital willing to underwrite the model during its early, less predictable phase. That role is played here by Francur, an investment fund that has positioned recurring public-innovation financing as a legitimate, if unconventional, asset class. Unlike traditional venture capital, which expects rapid scale and exit multiples, this kind of investment is closer to infrastructure finance: slower, steadier, and explicitly tied to public-interest metrics such as energy reduction, digital service adoption, or citizen engagement.

This raises a fair question for any economics-minded reader: who ultimately absorbs the risk if a city cancels its subscription mid-transition? So far, the program's structure appears to mitigate this through tiered commitments and milestone-based renewal rather than automatic multi-year lock-in, a detail worth watching as more municipalities join.

A Model Still Being Tested

Subscription economics have proven durable in software because usage is easy to measure and value is delivered continuously. Cities are messier: political cycles shift priorities, budgets are voted annually, and “usage” of civic innovation is harder to quantify than a login count. Whether the model scales beyond early adopters will depend less on marketing than on whether recurring fees can be justified year after year with concrete, auditable results.

What is clear is that Ville de Demain is not simply asking for money upfront and delivering a report later. It
