Evidence of network execution
The Natal validation connected actors from two different sectors through a shared territorial model. This provides early evidence that the network can operate beyond a single organisation or service.
From pilot to infrastructure
The next step is not to reinvent the model. It is to instrument, standardise and replicate the validated circuit through a digital layer that can support new territories and participants.
Core circuit
From circular resource to preventive health.
The MVP focuses on making this value flow visible, measurable and repeatable before expanding functionality or geography.
01
Resource
Second-hand goods enter the circular ecosystem.
02
Economic activity
Local businesses create transactions and economic value.
03
Credit
Eligible value can support health credits or vouchers.
04
Health action
Credits connect people to preventive health activities.
05
Impact
Actions generate measurable evidence for communities and partners.
Platform architecture
Three systems. One impact loop.
AI
AI Monitoring Platform
A digital health layer designed to support risk monitoring, predictive workflows and integration with clinical information.

About CollabStich
Circular economy and preventive healthcare, connected.
CollabStich is a health-impact and circular-economy platform built around a simple idea: local economic value can become part of the financing mechanism for preventive healthcare.
By connecting second-hand businesses, healthcare practices, professionals, universities and communities, the platform creates a digital layer for registering economic activity, credits or vouchers, health actions and measurable impact.
The model has been validated in Natal, Rio Grande do Norte, Brazil, through a network involving 50 second-hand businesses and 20 healthcare practices, reaching approximately 4,000 people.
CollabStich is now focused on turning that territorial validation into repeatable infrastructure that can be deployed across new communities while maintaining traceability and impact measurement.
