Plinq: A Growth Marketer With No Code Skills Built a $456K ARR Safety App in 45 Days

This story is different from the usual AI startup coverage. It is not about a technical founder optimizing margins or a VC-backed team chasing a market. It is about a woman in Brazil who watched someone die because information that should have been accessible was not. And then she built something about it.

Sabrine Matos is a growth marketer. Not an engineer. Not a product manager. A growth marketer with zero coding skills. She used Lovable, an AI coding platform, to build Plinq in 45 days. Three months later, it had 10,000 users and $456K ARR.

The Story Behind Plinq

A woman in Brazil was murdered by her partner. He had a violent criminal record. She never knew.

This is not a rare occurrence. Brazil has one of the highest rates of gender-based violence in the world. According to monitoring data, 37.5% of Brazilian women aged 16 and older experienced some form of violence in a single 12-month period. Many of these cases involve partners with known criminal histories that victims had no way to check.

After the femicide, Sabrine's mother said something that changed her trajectory: "You have to do something. Women here have no access to this kind of information until it is too late."

So she did something.

What Plinq Actually Does

Plinq connects to public criminal and legal records databases in Brazil. It takes information that technically exists in public records but is practically impossible for regular people to access, and makes it simple.

The core features:

• Background checks on potential dates, new acquaintances, or anyone you want to verify
• Risk scoring using a green/yellow/red flag system based on criminal history
• Panic button that instantly sends your location to emergency contacts
• Safety content feed with practical information for staying safe

Think of it as background screening that was previously only available to corporations and HR departments, but now accessible to individual women for personal safety.

Built in 45 Days With Zero Code

This is the part that makes Plinq a zero-human story. Sabrine built everything on Lovable. The website. The desktop app. The backend workflows. All of it.

Sabrine said it directly: "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."

45 days from idea to working product. For context, a traditional development agency would quote 4 to 6 months and $50,000+ for something similar. Sabrine did it herself with an AI tool.

This is what the zero-employee model looks like when applied to a problem that genuinely matters. Not another SaaS dashboard. Not another productivity tool. A product that has literally prevented over 200 dangerous situations for real women.

The Growth Numbers

Plinq's traction is remarkable for a first-time founder with no technical background:

• 10,000+ users in the first three months
• R$2.2M (~$456K USD) ARR
• 300% month-over-month growth
• 200+ potentially dangerous situations identified and avoided

Lovable themselves highlighted the story, calling out the $456K ARR and 10K users as an example of what their platform enables. When the platform you build on is using your success story as marketing, you know the numbers are real.

Lovable's CEO Invested

The story gets more interesting. Anton Osika, founder and CEO of Lovable, personally invested in Plinq. The company is raising a pre-seed round of R$1.5 to R$2 million (roughly $500K USD), and Plinq projects reaching R$10 million in revenue in 2026.

When the CEO of the AI platform you built on puts his own money into your company, it sends a signal. It means the product is real, the traction is real, and the market opportunity is real.

Why This Story Matters for Zero-Human Building

There are three things that make the Plinq story worth paying attention to beyond the impressive numbers.

Non-technical founders can build real products now. Not toy projects. Not landing pages. Real, revenue-generating products with thousands of users. The barrier to entry for software is effectively gone. If you understand a problem deeply enough, you can now build the solution yourself.

The best AI-built products solve real problems. A lot of vibe-coded projects are solutions looking for problems. Plinq started with one of the most urgent problems imaginable: women dying because they could not access public safety information. The AI was just the tool. The insight was human.

Growth marketing skills transfer directly. Sabrine is a growth marketer by trade. She knew how to acquire users, measure retention, and optimize funnels. She just did not know how to code. AI removed that one blocker, and her existing skills did the rest. If you already know how to grow a product, AI tools let you build one too.

The B2B Expansion

Plinq is not stopping at consumer safety. Sabrine is building a B2B version for HR departments and employers. The same criminal record verification technology, packaged for corporate background screening.

This is a smart move. The consumer product builds brand awareness and social proof. The B2B product generates higher-margin, more predictable revenue. It is the kind of strategic thinking you would expect from a growth marketer, and it suggests Plinq has staying power beyond the initial viral moment.

A Different Kind of AI Story

Most of the AI founder stories we cover on this site are about efficiency, scale, and automation. Polsia is about AI running entire companies. Base44 is about building software at impossible speed. These are stories about doing more with less.

Plinq is about something different. It is about a technology giving someone without traditional technical skills the ability to solve a problem that was literally killing people. That is not optimization. That is access.

The next wave of AI-built products will not all look like developer tools and SaaS platforms. Some of them will look like Plinq. Built by people who understand problems deeply, used by people who need solutions desperately, and made possible by AI that removed the last barrier between the idea and the product.
