What is Fefi?

Fefi turns company filings and market data into auditable answers through a chat interface, a research terminal and an API, aimed at analysts, investment teams and developers building financial agents.

Fefi is financial markets infrastructure aimed at AI agents, packaged as a terminal, a chat interface and a dedicated API. The core idea is that an agent should be able to take a plain question about a company, work out which statements and disclosures it needs, pull the numbers and hand back an answer with the supporting evidence attached. The product page frames the workflow in three stages: reasoning over the prompt, extraction of financials and market data, and auditing against the original source. The chat product is the easiest place to see this. A request such as comparing revenue growth across a group of companies triggers a chain in which Fefi loads the relevant income statements, searches through filings, then returns charts, key metrics and growth rates in one response. Every figure can be traced back to the filing or extract it came from, including standard SEC forms such as 10-K and 10-Q, so the output is inspectable rather than a black box answer. The Terminal is the heavier workspace, bringing real-time and historical market data, company fundamentals, filings and analysis into one screen, with peer, sector and historical performance comparisons and exportable data. Teams that would rather wire the data into their own tooling can use the API for statements, KPIs, filings and company disclosures, with limits configured to the account. Fefi is pitched at investment professionals, research analysts and developers building financial platforms or agents, rather than at casual retail investors. It sits in the same territory as AI research assistants that lean on filings, but its distinguishing claim is the audit trail and the API-first delivery, which matter more to teams that need to verify a number before it reaches a memo. Pricing is quoted per engagement, with custom API and enterprise tiers and no published self-serve rates.

  2. 2Ask a comparative financial question
    Type a natural language request, for example comparing revenue growth between a company and its peers over several years. Fefi works out which statements and filings are needed before answering.
  3. 3Review the returned charts and metrics
    The response arrives with financial data, growth rates and charts. Check that the companies and periods matched what was intended before relying on the numbers.
  4. 4Audit each figure against its source
    Open the citation behind any answer to inspect the original filing, source extract or underlying reference and confirm the value was read correctly.
  5. 5Move data into your own workflows
    Use export from the terminal or the API to bring statements, KPIs and disclosures into internal models and agent pipelines.
