LeanMarket
LeanMarket was a mobile advertising technology company headquartered in Mountain View, California, that brought real-time bidding (RTB) display advertising to small and mid-sized advertisers through a self-serve platform. Its pitch was transparency and operator control: advertisers could pull reports showing in-depth data on every mobile app and mobile website their ads appeared in — in contrast to blind ad networks — and could tweak, optimize and scale campaigns themselves through a self-serve interface with up-to-the-second reporting, rather than waiting on an account manager to make changes. The company went through the Y Combinator Summer 2012 (S12) batch and appears on the Andreessen Horowitz investment list, with seed participation also reported from Initialized Capital. LeanMarket is defunct and operates no live product, developer portal or API today; this profile is retained for historical and network completeness.
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.
LeanMarket 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 — LeanMarket scores 6.8/100 (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.

LeanMarket 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.
