LSEG Workspace — the terminal formerly known as Refinitiv — earned its place on professional desks, and the data runs deep across global markets. It's also a seat-based workspace: a dense, feature-packed environment sold to institutions, where finding the right screen is a skill of its own.
Massari is built for the research itself. Ask in plain English and an AI analyst does the work — grounded in SEC filings, every figure traceable to its source. No enterprise contract, no workspace to master, and it connects to the AI you already use.
Just ask
Plain-English questions instead of hunting for the right screen in a dense workspace.
No gatekeeping
Self-serve access — no seat license, no enterprise sales cycle.
