OlhoAberto

A training and anonymous-reporting app in Portuguese that teaches building staff, neighbors, and health workers to spot the signs of domestic servitude (isolation, no documents, never alone, fear) and submit a confidential tip that routes to the Brazilian Labor Prosecutor's Office.

Target user

Portateiros, neighbors, doctors, and social workers in Brazilian cities who interact with live-in domestic workers and may be the only outside contact a victim has

Features
  • Scenario-based training module (10 cases drawn from real Madalena/Maria-style rescues) with red-flag checklists
  • Anonymous tip form with photo, address, and free-text description that encrypts and forwards to the Ministério Público do Trabalho
  • Resource directory by city of shelters, legal aid, and Bolsa Família re-enrollment support
  • Post-rescue follow-up tracker so trained users see the impact of their reports
Why now

A 55-year case just emerged in Fortaleza where neighbors and authorities missed obvious signs for decades; Brazil's Labor Prosecutor's office explicitly says anonymous tips are how these cases are increasingly uncovered.

Signals · overall 5/10
Demand
4/10

The 55-year Fortaleza case is confirmed real and trending, and Brazil's government ran a 2023 campaign explicitly routing anonymous tips via Disque 100, proving latent concern — but the public-facing pull is captured by free government channels, not by a third-party observer app.Woman rescued in Brazil after being enslaved for 55 years by three generations of the same familyMinistry launches campaign against domestic slave labor

Whitespace
6/10

No app found that trains porters/neighbors/clinicians to spot signs; the closest, Laudelina, is targeted at the workers themselves and only added a denunciation channel in 2023, leaving the third-party-observer training angle genuinely open — though the reporting half overlaps with Disque 100 and IPE.App para domésticas ganha atualização para facilitar denúncia de trabalho análogo à escravidãoAplicativo Laudelina divulga direitos de trabalhadoras domésticas

Monetization
2/10

Every comparator is free: Laudelina (state-backed), Disque 100, the MPT ouvidoria (158), and gov.br's anonymous channel — target users (porters, neighbors) have near-zero willingness to pay, leaving only fragile NGO/grant funding, which is why starting score of 3 was already optimistic.Aplicativo Laudelina — Google PlayCanal Denúncia — gov.br

Longevity
6/10

Domestic servitude in Brazil is structural (long-running reports from MPT/CONAETE) and the Fortaleza case may catalyze sustained policy attention, but governments and large NGOs tend to absorb these functions over time — risk that an independent app is rendered redundant within a few years.Ministério Público do Trabalho — CONAETEMinistério dos Direitos Humanos cria protocolo para receber denúncias sobre trabalho escravo doméstico

Feasibility
6/10

Technically straightforward (training content + tip form that forwards to MPT/Disque 100), but requires Portuguese-language subject-matter expertise, ongoing legal review, and a formal partnership with the Labor Prosecutor's Office to actually route tips — not trivial but buildable by a small team.Realizar Denúncia Trabalhista — gov.br
