Move from questions to evidence across connected financial and economic data. Built for investors and analysts who work in code.
Explore through focused interactive workflows, or let your coding agent prepare the investigation.
Your question determines the interface.
Jefferson Street chains focused research steps into an interactive environment for the question at hand. Search for what you know, discover what you don't, and rank what stands out—without navigating a monolithic application.
Compose only the tools the investigation needs.
Let your agent prepare the investigation.
Give your coding agent a research question. It can find the relevant data, interpret what stands out, and compose a workflow for you to investigate it.

Take your research with you.
Your research shouldn't be trapped in an interface—or a conversation. A Session preserves the investigation so you, your agent, and your code can pick up where the last one left off.
One research state. Use the interface that fits the work.
Follow relationships, not datasets.
Jefferson Street connects entities, metrics, and series across sources into one research model. Humans can explore those relationships interactively; agents can traverse the same model programmatically.
One research environment. Multiple domains.
Companies & Fundamentals
Financial metrics for thousands of public firms.
Economic Data
Integration with FRED for macro-indicators, labor stats, and yields.
Markets
Daily stock prices and volume for domestic equities.
