Qartt

Product Overview

Qartt is a business-grade, on-demand delivery platform developed by Qartt Ltd, a London-based last-mile logistics company. It's a marketplace that connects local businesses — restaurants, pharmacies, grocery stores, and similar merchants — with a pooled fleet of gig drivers, giving them flexible courier capacity without the cost and complexity of running an in-house delivery team. On the other side of the marketplace, Qartt offers drivers income opportunities with adaptable schedules, making the platform dual-sided by design.

The core workflow is built for speed: a business requests a driver through the app in just a few taps, tracks the pickup and delivery in real time, and pays transparent, tiered fares — no fleet management, no dispatch overhead. Drivers accept jobs on their own schedule, giving Qartt the elastic capacity to serve demand spikes that a fixed in-house fleet couldn't absorb. The result is fast, reliable delivery service that reduces operational overhead for the merchants who rely on it.
