ImpulsoGov is a Brazilian nonprofit healthtech that turns public health data into action. Brazil's universal health system covers 210 million people and holds the world's largest public health database. Yet despite this wealth of information, a preventable death occurs every nine minutes. ImpulsoGov's mission is to close that gap, helping municipalities use the data they already have to identify and reach the citizens who need care before it is too late.

Today the organization operates across more than 330 municipalities in 25 Brazilian states, reaching four million citizens directly at a cost of just 70 cents per person. Their organizational goal is bold: to go from saving one life every 2.3 days to saving one life every hour. "To close that gap, we need a data platform that is reliable and that lets us generate impact and save lives in hours, not months," says Victor Souza, chief technology officer.

The infrastructure the organization had built wasn’t going to get them there. ImpulsoGov had always used Google Cloud, but alongside external services including a separate cloud provider, and was underusing the tools already available to them. As the number of municipalities grew, the original architecture could no longer keep pace: every day, it required a full data pull from all municipalities, rather than processing only incremental changes. A single database was handling workloads it wasn’t designed for, processing times were growing, costs were rising faster than the municipality base, and the team had no visibility into how much each city or each health condition was actually costing them. "With 65 municipalities the model was reaching its limit," Souza explains. "With 330 or more, it becomes mission impossible."

The decision wasn’t to change providers, but to finally use Google Cloud the way it was designed to be used, with support from the Google team and participation in the Google for Nonprofits program helping make it possible.

The shift to transmitting only daily changes reduced monthly data traffic by four times and cut pipeline execution time from 20 hours to 12, with a target of four to five hours once the full migration is complete.

Security was rebuilt alongside the architecture. All resources run in São Paulo, keeping citizen data in Brazilian territory. Access to sensitive production data requires justification and expires automatically, with a full audit trail for every access request.

The numbers tell part of the story. Data pipeline failures that once occurred weekly and took up to five days to resolve are now rare and resolved in one to two days. The organization expects to reduce total infrastructure costs by up to 60% while running comfortably at 330 municipalities and ready to scale further.

The speed of the platform is itself a form of care. "When we are fast, it creates a cycle of engagement," says Helena Alves, tech product manager and analytics engineering lead. "Health professionals use the platform more frequently and incorporate it more into their routines. And that generates more impact on the health of the population."

That engagement is what turns a technology platform into a public health tool, shifting the entire model from reactive treatment to proactive prevention, the principle behind “Busca Ativa” (active case-finding), a public health strategy in Brazil's national health system that ImpulsoGov's technology helps put into practice.
