Last mile is a $500B industry powering digital commerce but managed largely with self managed API integrations. Nash approaches last mile orchestration with information completeness solutions from checkout, courier management, customer engagement, and post-purchase experience. Doing this enables merchants and customers to capture immense efficiencies, drive better customer experience, reliability and business outcomes.
We are working towards a mission of processing a double digit percentage of every physical last-mile transaction. We achieve this by providing top of the market modules for each step of the customer journey and leveraging the network effects from having more information that allows traditional competitors to collaborate. It’s a big mission, but we are already seeing strong market pull as we are already serving some of the largest retailers in the world like Walmart, 7-Eleven and Woolworths.
Nash was founded in 2021 by Mahmoud Ghulman (2x Founder, MIT) and Aziz Alghunaim (2x Founder, 2x YC, Ex-Palantir, MIT) and has raised funding from top investors, including Y-Combinator and a16z, to build the world’s best logistics infrastructure platform. We are based in SF.

Nash is the AI infrastructure for logistics.
Merchants juggle dozens of delivery providers, each with different APIs, SLAs, and workflows. Disconnected systems create blind spots. Manual operations burn resources. Customer experience suffers.
Nash is the infrastructure built to solve this complexity.
We power hybrid orchestration across internal fleets and third-party providers, connecting to 1000+ global delivery providers on a single platform. We consolidate every delivery type (same-day, scheduled, shipping, returns) into a single data model. This complete context enables our AI models to make intelligent decisions at critical moments across the delivery journey.
From fleet management to dynamic dispatch, from accurate delivery promises to automated returns, Nash orchestrates it all. AI agents handle customer support. Fraud detection protects margins. Proactive intervention prevents failures before they happen.
The result: reliable delivery at scale, dramatically lower operational costs, and customer experiences that actually build loyalty.
We power 100M+ deliveries annually for some of the world's largest retailers and for merchants of all sizes through Square, Shopify, and Toast.
Founded by Mahmoud Ghulman and Aziz Alghunaim (both 2x founders, MIT). Backed by Rackhouse Ventures, Y Combinator, and Andreessen Horowitz.
