Case Study
QUERVY — Offline Survey App

Offline-first Android survey app for field data collection in remote greenhouses — dynamic question logic, digital signatures, and automated EU compliance reporting.

The Client

Carbominer, Ukraine

Carbominer is a Ukrainian hardware startup that develops modular Direct Air Capture (DAC) technology to extract carbon dioxide CO2 directly from the atmosphere. Their field teams operate across remote greenhouse sites, requiring precise data collection and MRV-ready compliance reporting for EU green energy standards.

The Challenge

Data Loss in the Field

The lack of offline reporting tools in rural greenhouses led to fragmented data collection, significant information loss, and weeks of manual administrative work to meet strict compliance standards. Without automated verification, the team struggled with inconsistent audit trails and manual transcription errors that delayed essential ROI analysis for green CO2 transitions.

Offline-first — captures every entry even with no signal.

Field Team Adoption

95%

Deployed across international teams without training overhead.

Impact Delivered

Carbominer's field teams no longer lose data in remote greenhouse environments — QUERVY captures every audit entry offline, syncs automatically when connectivity returns, and delivers MRV-ready compliance reports that previously took weeks to compile.

"QUERVY has been a lifesaver for our field audits — the team can finally ditch manual notes even deep in rural greenhouses with zero signal. The automated tracking and easy syncing give us exactly what we need for EU compliance, without the usual administrative headache."
— Nick Oseyko, CEO, Carbominer
