Sabrine Matos, a growth marketer from Brazil, founded Plinq, a women's safety app enabling users to perform instant criminal record checks to prevent violence and femicide. Motivated by a personal tragedy and the high rates of gender-based violence in Brazil, she developed Plinq using Lovable, a platform that allowed her to bring her idea to life without a technical background. Plinq is designed for individual use, offering fast access to public criminal and legal records, unlike traditional, business-oriented background check services. In just three months, Plinq gained over 10,000 users and achieved a significant revenue milestone, prompting a pre-seed funding round to support further growth. The app's features, such as risk scoring and a panic button, aim to improve women's safety, while a forthcoming B2B version will cater to HR and employer needs. Sabrine emphasizes the importance of rapid iteration based on user feedback and focusing on real-world needs, demonstrating the impact of accessible technology on solving urgent societal issues.
