DoorDash is a leading technology-driven on-demand food delivery platform that connects customers, local restaurants, and delivery drivers (called Dashers) in a seamless marketplace. Founded in 2013 by four Stanford students—Tony Xu, Stanley Tang, Evan Moore, and Andy Fang—DoorDash began as PaloAltoDelivery.com, pioneering a model where the platform itself managed deliveries rather than just listing restaurants[6]. It rebranded as DoorDash, joined Y Combinator, and quickly expanded across U.S. cities, achieving a valuation over $600 million within two years[6]. The core of DoorDash’s business model is its **Y-structure platform** that simultaneously serves three groups: consumers seeking convenient food delivery, restaurants looking to expand their customer base without building delivery infrastructure, and Dashers who get flexible earning opportunities[1][5]. The platform emphasizes usability, with features like real-time order tracking, AI-powered personalized recommendations, and easy reordering, enhancing customer convenience[1][3]. For restaurants, DoorDash acts as both a digital storefront and logistics partner, facilitating order volume growth especially for small or independent eateries[1][3]. Dashers choose when to work and manage their own expenses, with DoorDash optimizing routes and order assignments through advanced logistics algorithms[1][2]. DoorDash has diversified beyond restaurant meals into delivering groceries, alcohol, pet supplies, and convenience store items, aiming to become a comprehensive last-mile delivery solution[2]. It generates revenue through commissions from restaurants (around 20%), delivery and service fees charged to customers, subscription plans like DashPass, software-as-a-service tools for restaurants, and advertising[4][8][9]. Currently, DoorDash dominates the U.S. market with about 35% share, surpassing competitors like GrubHub and Uber Eats, and operates in over 4,000 cities across the U.S., Canada, Australia, Japan, and Germany with over one million Dashers[6][5]
