About the Company

Wolt

On-demand delivery platform for food

Wolt is an on-demand delivery platform based in Helsinki that connects customers with local restaurants and stores to deliver food and other goods. How it works: users order via a mobile app or platform, and Wolt’s technology routes orders to nearby couriers who are independent contractors. Couriers pick up items from partners and deliver them to customers; the app handles payments, including delivery fees, service charges, and commissions for partners, with customers able to tip couriers directly. Differences from competitors: Wolt combines a broad network of partner restaurants and stores with a route-optimizing platform, offers flexible earnings for couriers, and supports tipping through the app, all aimed at making deliveries quick and convenient. Goal: to provide a seamless, efficient delivery experience by leveraging technology to optimize routes and timing.
