Swiftly

Swiftly (Swiftly Systems, Inc.) is a Seattle-based retail technology company that sells an AI platform purpose-built for grocery, convenience and wholesale retail. It powers white-labeled shopper mobile apps and websites for regional and independent retailers, and runs a multi-retailer closed-loop retail media network that lets brands buy targeted advertising against first-party shopper data. Products include the Marketing and Operations AI Stacks, Swiftly Connect (POS / loyalty / inventory / supplier data unification), Audience Optimizer, SmartCircular digital circulars, Alcohol Cashback (from the BYBE acquisition) and Retail Media. The company reports live transactions, 9 million products and closed-loop campaign outcomes across roughly 33,000 storefronts. Swiftly has raised more than $200M and trades on the Forge Global secondary market. Swiftly publishes no public developer program: the shopper-facing GraphQL API behind its retailer apps is anonymously introspectable at prod.swiftlyapi.net/graphql, but there is no developer portal, no reference documentation and no published SDK.

Swiftly publishes 1 API on the APIs.io network. Tagged areas include Retail, Retail Media, Grocery, Advertising, and Loyalty.

Swiftly’s developer surface includes engineering blog, product news, support, authentication, and 20 more developer resources.

    rewards and challenges, shopper accounts and age verification, and retail-media ad placements. The endpoint is not documented
    publicly, but introspection is enabled and returns a 308-type schema. Discovered from the Swiftly-built savemart.com storefront.

x-discovery:
  note: Swiftly publishes no developer portal, documentation or spec. The GraphQL API behind its white-labeled retailer apps
    was found on the API host referenced by the Swiftly-built savemart.com storefront, and answers anonymous introspection
    with a full 308-type schema. Recorded here so a later round does not repeat the hunt.
