Our products

What we offer

Three services that give your buyer confidence and your business a competitive edge in the circular device market.

Verified Quality

We grade every device to your specific criteria, not ours. Functional testing, cosmetic inspection, and battery health checks, all documented per serial number. Your buyer gets independent verification they can trust.

  • Custom grading schemas per customer
  • Functional + cosmetic + battery testing
  • Per-serial documentation with photos
  • Independent third-party verification

Device Intelligence

Every device that passes through our facility is enriched with real-time market data. Know exactly what each device is worth based on model, storage, condition, and current market demand across 15 countries.

  • Real-time market valuations
  • 30+ pricing sources across Europe
  • Grade-level price breakdown
  • Trend analysis and demand signals

Proofen Reports

Every batch gets a comprehensive report, available as per-serial PDFs or a shared URL your buyer can access directly. Grade, photos, technical QC results, and market context all in one place.

  • Per-serial PDF reports
  • Shareable batch URL for buyers
  • Grade photos and QC data
  • Market context and valuation

The bigger picture

Building the trust infrastructure

Quality verification is just the start. We're building the infrastructure that makes the circular device market work.

Grade Standardisation

We normalise grading across the industry. Whether your buyer expects A/B/C or Good/Fair/Poor, we map your schema to theirs.

Cross-border Trust

Proofen Reports work across borders. A buyer in Germany trusts the same report a seller in the Netherlands generated.

Supply Chain Transparency

Full traceability from intake to buyer. Every device has a verifiable quality history.
