Magma

Data-licensing service for companies that build AI agents: it connects read-only to the traces, corrections and completed workflows an agent already produces, packages them with the company's approved scope and licenses them to AI labs and researchers, paying the company a revenue share; onboarding by form and a short call.

Magma Data service

Data-licensing service that packages the interaction data an AI agent already generates, its traces, corrections and completed workflows, and licenses it to AI labs and researchers; the customer approves the scope, the connection is read-only and encrypted, and the customer earns a revenue share as the data licenses under a data agreement signed at onboarding; no prices are published.
