Compare the operating role before comparing scale
A discovery marketplace, employer meal service, kitchen operator and merchant software provider solve different problems. Country coverage, registered users, active customers, kitchens, revenue and gross order value are different measures. They cannot be combined into one size ranking without matching definitions, period, currency and geography.
The following primary sources were reviewed November 10, 2026. They provide business context, not a consumer ordering directory or a claim that Ordering.co integrates with every company.
Deliveroo: merchant marketplace and corporate meals
Deliveroo's UK merchant page distinguishes rider delivery, merchant-owned rider fulfillment and other service options. Its UK corporate catering announcement, published in 2026, describes catering within Deliveroo for Work. “Deliveroo for business” can therefore refer to selling as a merchant or feeding employees; identify the buyer, service and market before comparing fees or workflow. A corporate meal allowance is not the same operating product as a restaurant listing.
Keeta: a dated country and region footprint
Keeta's official service-area sitemap lists Saudi Arabia, Kuwait, Qatar, United Arab Emirates, Hong Kong, Brazil and Bahrain as countries/regions served at the review date. Hong Kong is a region in that list. The partner privacy policy, updated February 11, 2026, identifies operating entities. A country entry does not imply every city or address is covered, and legal-entity registration alone is not evidence of a live service. Confirm the local service area when evaluating expansion.
Rappi: multiple merchant categories and local markets
Rappi's Colombia merchant portal separates restaurant and other commerce onboarding and links country-specific partner paths. That illustrates a local-commerce marketplace with operating and commercial requirements by market. A registered-user total, an active-customer count and share of orders in one city would tell different stories. The cited portal does not provide a comparable current customer census or independently defined market share; do not infer leadership or buyer demand from its country menu. Explore the Rappi operating context when separating marketplace orders from fulfillment.
Fantuan: community focus and local services
Fantuan's own company page describes its Vancouver founding in 2014 and cities served in Canada, the United States, Australia and the United Kingdom. It connects users, merchants and couriers and publishes its own headline activity figures. Those figures are company statements with their own definitions, not directly comparable to another platform's registered users or annual transacting customers. The builder lesson is a focused community proposition and local supply, rather than copying a global app catalog.
Waitr and ASAP: a historical case, not a current provider
Waitr Holdings' ordering division stopped delivery in February 2024 and carryout in March; its April 2, 2024 SEC notice records Chapter 7 filings and cessation of substantially all operations. Use the updated Waitr, ASAP and Bite Squad chronology to study its historical regional model. It should not be presented as an active option for new merchant onboarding.
Kitopi: kitchen operations and a brand portfolio
Kitopi's brand directory separates delivery, dine-in and meal-plan concepts, including Circle Café, Biryani Pot and Under 500. A brand listed in the portfolio does not mean it is available in every kitchen or country. The cited official portfolio describes operating brands, not a dated consolidated revenue statement. No revenue figure is established here: funding, valuation, brand sales and company revenue should not substitute for one another. Read the Kitopi case for the kitchen-operator lens.
Slice: merchant technology around independent restaurants
Slice's company history dates its founding by Ilir Sela to 2010 and explains its origins in independent pizzerias. Slice's current product site presents online ordering, websites, POS, phone ordering, kiosks, a consumer app and merchant tools. This is a different proposition from an unrestricted courier network: merchant software and distribution can be bundled around a focused segment. A historical startup valuation is not current revenue, profitability or a guarantee of results for a new pizzeria. Read the Slice business case with that distinction.
Turn the examples into your own scope
Choose which party owns demand, catalog, preparation, delivery, support and funds. Use the market and operating framework below to compare ideas, then validate a marketplace idea before discussing the ordering foundation. Published scale can suggest questions; it does not validate your local unit economics.
Define which market you mean
The online-ordering software market concerns tools sold to businesses. A food-delivery marketplace connects consumers, merchants and couriers. Quick commerce concerns an assortment and fulfillment model built around rapid local availability. Courier fulfillment transports an order acquired elsewhere. Their software revenue, merchant sales and gross order value are different denominators.
Before using a market-size figure, record source, publication date, measurement period, country, currency and whether it measures software spend, consumer spend or platform revenue. Check whether grocery, restaurant meals and retail are included. A global forecast is context for research, not your addressable revenue or an Ordering.co feature.
Zomato and Blinkit represent different operating jobs
Eternal's Zomato page describes restaurant discovery and food delivery. Its Blinkit page describes quick commerce. Both sit within Eternal, the corporate group formerly named Zomato, but the Zomato consumer service and Blinkit's grocery/essentials proposition should not be treated as interchangeable. Saying the parent operates quick commerce is different from labeling every Zomato restaurant order quick commerce. Sources reviewed November 10, 2026.
For a builder, the distinction changes catalog, stock ownership, replenishment, picking, promised window and unit economics. A fast-looking app cannot create nearby stock or picking capacity, and a market trend does not establish a native workflow in any software product.
Instacart's launch is a dated company fact
Instacart's tenth-anniversary account, published in 2022, says its app launched in 2012. That establishes the launch year from the company, not a current market-share estimate or a founding-cost benchmark. Its evolution illustrates why a company can connect grocery demand with retailer technology without fitting a restaurant-delivery label alone.
Turn a trend into a testable marketplace idea
Consider a neighborhood restaurant marketplace, grocery service, specialty-product delivery, scheduled office meals or a merchant-owned direct channel with courier fulfillment. These are candidate models, not evidence that a specific territory needs another app. A specialty assortment may create differentiation; a narrow delivery zone may make service easier to operate; scheduled demand may change capacity planning. Each remains a hypothesis to validate.
For each idea, identify the customer problem, existing alternative, participating merchants, who sells the goods, who owns stock, who picks and delivers, and who pays the operator. Define the promise at one address and time window. Medical courier work, alcohol or other restricted categories require separate eligibility and specialist operating decisions; do not treat them as ordinary product switches.
Estimate contribution from the operator's actual revenue, subtracting payments, fulfillment, support, promotions, refunds and variable operation. Include fixed overhead and acquisition separately. A marketplace commission, retail product margin, subscription and delivery fee represent different business models. Do not count the merchant's whole basket as the platform's income.
Validate demand before expanding the model
Interview potential buyers about their last real purchase, recruit a small merchant set and test a bounded offer. Measure completed orders, repeat purchase over a defined interval, fulfillment failures and contribution with a consistent denominator. Compare ordinary days and peaks. Distinguish observed customer behavior from stated interest and from a national industry forecast.
Use the ordering demand-planning guide, the idea-validation sequence and the dated provider examples above to decide which questions need evidence. For grocery, compare operating models and local adoption. Then discuss the order flow that the business can actually operate.
