Building the trust layer for
service industries
Provn is the first review platform that proves the reviewer was physically present at the point of service. No more fake reviews. No more trust gaps.
The Problem We Solve
Open review platforms have a fundamental trust problem. Anyone can write a review without ever experiencing a service. Competitors leave fake negatives. Satisfied clients forget. The result: reviews that consumers don't trust and professionals can't rely on.
For service professionals — where trust is everything — this is especially damaging. A single fake review can cost thousands in lost business. And the platforms that host these reviews have no way to prove the reviewer was ever actually there.
How We're Different
Every Provn review proves three things:
They were there
GPS verification proves the reviewer was physically at the location
They are real
Pre-assigned QR codes tied to named, verified recipients
It's recent
Reviews triggered hours after the interaction, not months later
Our Story
Provn is built by Jacaranda Labs. We started with the Portuguese real estate market because it's where the need is most acute — a market built on personal relationships where trust is the primary currency. Agents meet clients face-to-face for property viewings, but online reviews don't reflect that reality.
The platform is designed to expand to any service industry where professionals meet clients in person: hospitality, healthcare, automotive, education, legal, and consulting. If there's a physical location and a client interaction, Provn can verify it.
Our Principles
Privacy by design
Raw GPS coordinates are discarded after verification. We store only the distance and result. No tracking cookies on consumer-facing pages.
API-first
Every feature is accessible via our REST API. The dashboard consumes the same API as external developers. Open and transparent.
White-label by default
Your brand, not ours. Provn disappears behind your identity. Your clients see your name on every touchpoint.
No shortcuts
We don't display fake social proof, inflated metrics, or awards we haven't earned. The product speaks for itself.
