Jumba

Jumba is a Nairobi-based construction technology company founded in 2022 that digitizes the sourcing and financing of construction materials across Africa. Its B2B marketplace connects hardware retail stores and construction sites to manufacturers and suppliers of materials such as cement, steel, tiles, plumbing, electrical, paint and finishes, offering real-time price comparison and online ordering. Jumba OS is a management application for tracking sales, inventory and creditor accounts, while Jengwa provides buy-now-pay-later inventory financing. The company operates a consumer mobile app and reports processing over 12.6 million cement bags through more than 1,350 hardware stores, and is backed by Speedinvest. Jumba does not publish a public API; its developer presence is limited to open-source tooling on its GitHub organization.

human only

Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.

Kin Score

Jumba is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Jumba scores 11.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

The organization behind the API

Jumba is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
