Decide Madrid

The bet

Decide Madrid came directly out of the 15-M anti-austerity movement of 2011, which had demanded that Spanish institutions find real ways to let citizens shape decisions. When Manuela Carmena's Ahora Madrid won the city in 2015, it delivered on that demand with a platform. Any resident could post a proposal, support others, debate, and help decide part of the municipal budget. The promise was concrete and unusually bold: proposals that reached enough support would be implemented directly by the city. This was not a consultation to be noted and filed. It was meant to be binding, bottom-up democracy at the scale of a capital city.

Peak

It became the reference case for the whole field. Registered users grew from 180,000 in 2016 to more than 460,000 by 2020, some periods saw between 800 and 2,400 citizen proposals a day, and the participatory budget expanded from €30 million to €100 million. In 2018 it won a United Nations Public Service Award. Its open-source software, Consul, was picked up by Paris, Turin, Buenos Aires, and dozens of other cities, and Barcelona's Decidim began as a fork of it. For a few years, Decide Madrid was what everyone pointed to.

What worked

The mobilization was real, and that matters. Hundreds of thousands of people registered and used it, which put to rest the claim that citizens will not show up for online participation. The participatory budget, alone among the formats, had a monitoring process and produced tangible results. And the decision to build it open-source gave the effort a life far beyond Madrid: the software now runs in dozens of countries, stewarded since 2019 by an independent foundation. As an engine of participation, it delivered.

What failed — the mechanism

The platform let citizens act but kept the door to power almost shut. A proposal had to win the support of two percent of the entire municipal census to be implemented, a threshold so high that when nothing reached it, the city merely lowered it to one percent, and even clearing the bar did not guarantee that anything happened. Worse, for every format except the participatory budget there was no formal feedback at all. Citizens could not learn whether their proposal had been read, used, or rejected, or why. Input went in and silence came back. Participation without a reliable response curdled into disillusionment, and the flagship street projects on Gran Vía and Plaza España ended up not reflecting what people had asked for. Because the platform belonged to one administration rather than to the city as an institution, the 2019 election that replaced Carmena with a conservative government could cut its budget, wind down its processes, and discard 182 proposals that had already been approved. Almost none of it turned out to be the citizens' to keep.

What Agora takes from it

Decide Madrid failed at the precise point Agora's hardest mechanic is built to hold. Its documented flaw was the absence of any acknowledgment: citizens never learned whether their input mattered. Closing that void is the whole point of acknowledgment and follow-through, so that citizen input is acknowledged rather than absorbed into silence. The case is also the clearest argument that a participation channel is worth little without a dependable path to a response and a consequence, which is the difference between a genuine channel to power and a suggestion box a government can ignore or switch off after the next election. That is why Agora is built for the long years between elections rather than for a single administration's goodwill.
