Builder Background
Sabrine Matos has spent most of her career in growth marketing, helping organizations launch products at scale. Embedded inside product teams, she always had a sideline view of product development, watching engineers turn ideas into reality, but never equipped enough to build herself.
That changed when a tragic story hit close to her home in Brazil: a woman murdered by her partner, a man with a violent criminal record she never knew about.
My mother told me: you have to do something. Women here have no access to this kind of information until it’s too late.
That moment marked the turning point. Sabrine decided to go all in on making a difference in women's safety and turned to Lovable to help turn her idea into a working product. Without a technical coding background, she launched what would become Plinq.
The Build: Plinq
Brazil faces one of the highest rates of gender-based violence in the world. A recent report shows that 37.5% of women aged 16+ in Brazil experienced some form of violence in the past 12 months, the highest rate recorded since monitoring began in 2017.
Plinq was created out of this urgency. In just 45 days, Sabrine created a platform for women to conduct consumer-level background checks and identify potential safety concerns. By connecting to public data sources of criminal and legal records data, Plinq enables users to access background screening that would normally only be accessible to corporate organizations. Unlike slow, bureaucratic, business-focused background check services, Plinq is designed for individual users.
Traditional background check services exist, but they are slow, bureaucratic, and designed for businesses, not individuals.
I wanted to build something instant. Women should be able to know if someone they are close to has a history of violence or fraud so they can safely trust them*.*
Features & Functionality
Every part of the product was built on Lovable, from the front-end interface and scoring logic, to the integrations that connect to public records databases.
- Risk Scoring: Green/yellow/red flags based on public criminal history data
- Panic Button: Sends location to emergency contacts
- Content Feed: Information on prevention, safety, and relevant partner brand content
- B2B Version: For HR/employer use cases, launching later this year
Revenue
Plinq's revenue growth demonstrates an urgent market need for women's safety solutions. With early traction and a 300% MoM growth rate, Plinq hit R$2.2M in Brazilian Real (USD ~$456K), and is raising R$1.5–2M (~USD $500k) for their first seed round in partnership with angel investors.
Why Lovable Made the Difference
Sabrine didn't have formal technical training. What she did have was a mission and an urgent problem to solve. Lovable gave Sabrine a platform to prototype, launch, and scale without traditional development bottlenecks — helping her turn a life-saving idea into a product in record time.
If Lovable didn't exist, Plinq would never have seen the light of day. I built everything on Lovable — the website, the desktop app, the backend workflows — all without an engineering degree.
Lessons & Builder Tips
From Sabrine's experience building Plinq:
- Launch fast, iterate often: "Our MVP went live in 45 days. We refined based on feedback from real beta users, not guesses."
- Anchor in real-world needs: "Every feature came from understanding user problems first — safety, trust, and accessibility are core to building Plinq."
- Think beyond launch: "The capability to build is becoming easier, double down on marketing"
