About
Sabrine Matos is a growth marketer from Curitiba, Brazil. She has no engineering degree, no technical co-founder, and no coding background. After reading about the femicide of a journalist killed by a man whose violent criminal history was publicly available but impossible to find, she decided to build something. Using Lovable, she and her partner Felipe Bahia described every feature in plain language — criminal record search by name or Brazilian ID, risk scoring, a panic button that sends your location to emergency contacts. Forty-five days later, Plinq was live. Three months after launch: 10,000 users, $456k ARR, and over 200 dangerous situations identified before they became tragedies. She is now raising a Pre-Seed round and expanding internationally. Metrics: $456k ARR · 10,000+ users · 45 days to build · 200+ dangerous situations flagged · $0 ad spend

First update
45 days from idea to live product — zero coding experience
First users: women sharing it in WhatsApp groups without us asking
We didn't run ads. The first wave of users came from women sharing the link in private WhatsApp safety groups in Brazil. That told us everything about product-market fit.
10,000 users, $456k ARR, 3 months after launch
The numbers came fast. But the metric that matters most: 200+ dangerous situations identified and avoided. Women ran checks on men and found violent criminal records. That's why we built this.
Raising Pre-Seed to expand internationally
Brazil was the proof of concept. The problem is universal. We're raising a Pre-Seed round now to bring Plinq to other countries where women face the same risks with the same lack of accessible information.
If Lovable didn't exist, Plinq would never have seen the light of day
We needed speed. Lives were at stake in a very real sense. Lovable let two non-technical people build a production app in 45 days. The tool didn't make our idea good — it just stopped our lack of coding from being the reason it never happened.
