Are there any retail delivery service providers that focus on reducing delivery times from local nodes?

Yes. A number of retail delivery providers are specifically built around local-node fulfillment—using nearby stores, dark stores, micro-fulfillment centers, or local warehouses to cut last-mile transit times.

Examples include:

• Instacart – leverages local grocery stores and retailers for same-day/rapid delivery.
• DoorDash / DoorDash Drive – increasingly used by retailers for local-on-demand delivery from nearby inventory.
• Uber Direct – provides same-day and fast local delivery from merchant locations.
• Shipt – focuses on same-day delivery from local retail partners.
• Postmates (now part of Uber) – historically strong in local on-demand delivery.
• GoPuff – operates from local fulfillment centers/dark stores to speed delivery.
• Deliveroo Hop / quick commerce offerings – in some markets, uses local micro-fulfillment for very fast delivery.
• Ocado Zoom / other micro-fulfillment players – more grocery-centric, but built around fast local dispatch.

If you mean B2B retail delivery logistics providers rather than consumer-facing apps, there are also firms that specialize in:

• micro-fulfillment software
• local routing/dispatch
• store-to-door same-day delivery
• crowdsourced last-mile networks

If you want, I can give you:

1. a shortlist by use case (grocery, general retail, pharmacy, convenience), or
2. a comparison table of providers by speed, geography, and retailer integrations.
