learning is part of the impact

We believe learning is essential to generating impact: it is by learning that we understand how social change really happens — and design strategies that work. Our learning culture follows three paths: evaluating our strategies to know what works (and what does not), reflecting on the work together with those who live it in the territories, and researching the questions that run through digital inclusion and social innovation in the peripheries. All of it open — for consultation, critique and replication.

Multi-institutional territorial arrangements: shared governance

Organizations in our territories have been coming to us with an invitation to build together, not to execute an idea that arrived finished. Here is what we have learned in practice, alongside the Coalizão pelo Impacto training for ecosystem-building organizations, about structuring shared governance that survives the first surprise.

Doing It the Right Way, Always: Meet Our Integrity Program

After talking about data for artificial intelligence, data protection, and accessibility, today I share how we have advanced over approximately a year and a half of compliance and integrity work at Casa Hacker. This year we participated in a Neoenergia training program focused on third-sector compliance and left with good news: what we were already doing was aligned with what the sector expects. This is an inside look at the program—who leads it, what the Board of Directors and the Council assume, the policies, the training, the whistleblower channel, supplier vetting, what lies ahead, and what we have learned so far.

Security at Casa Hacker: how we protect the data of those who trust us

Casa Hacker spent the past months hardening its platforms before letting artificial intelligence in. This is the account of what changed: what it means to say a piece of data is encrypted, why our copies leave the country every day and cannot be erased, how Project Galileo put enterprise-grade protection within reach of an organisation from the periphery, and why a single person authorises every data transfer out. It includes what we still don't do — because an organisation that only tells the finished part is asking you to believe it rather than check it.
