Motley

Motley is a Zurich-based company building a governed semantic layer for AI agents and business intelligence. Its open-core product, SLayer (motley-slayer), is a lightweight, agent-first semantic layer and query engine: teams model measures, dimensions, and filters once, and SLayer generates and executes correct SQL across Postgres, MySQL, Snowflake, BigQuery, ClickHouse, DuckDB and more — exposed over MCP, a REST API, a CLI, a Python client, Apache Arrow Flight SQL, and a Postgres facade for BI tools. Motley Cloud adds the managed production layer on top: hosting, OAuth-based access control, row-level security, versioning, and a governed reporting engine that turns agent queries into reports, charts, documents, and presentations. Founded by Egor Kraev (ex-Head of AI at Wise), Artemy Belousov, and Yann Ranchere; backed by Seedcamp.

Motley publishes 1 API on the APIs.io network. Tagged areas include Company, Semantic Layer, Business Intelligence, Analytics, and AI Agents.

Motley’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, support, and 21 more developer resources.
