M Science

Analyst-curated alternative data research and KPI dashboards

M Science pairs alternative datasets with analyst-written research and dashboards tracking about 1,400 KPIs across roughly 1,400 public and private companies, with direct analyst access. A Jefferies subsidiary serving hedge funds, asset managers and corporates, it has added an AI copilot and an MCP server for querying its data from general LLM tools.

GAII take
MCP access makes it easy to pilot inside existing LLM tools; review Jefferies ownership for any information-barrier concerns.
