Signals.AI is an AI toolkit for equity research. It reads everything a company puts out, the filings, the earnings calls, the slide decks and the investor presentations, and turns it into research you
What is Signals.ai?
Signals.ai is an AI equity research tool.
Companies say more than they file. Signals.AI covers both for every US-listed company: the SEC filings, and the earnings calls, slide decks, press releases and investor day material companies publish themselves.
Deep research on a company. Business model, financials, ownership, risks and competition, assembled end to end and exported as a cited PDF.
Operational KPIs. The numbers management reports but nobody files in a standard format. Backlog. Remaining performance obligations. Annual recurring revenue. Net revenue retention. Same-store sales. Segment revenue. Pulled from company documents and earnings call transcripts.
Ownership and insider activity. Institutional positions from 13F, insider trades with cluster detection, and congressional trading disclosures.
Earnings analysis. What changed this quarter. Guidance revisions, prepared remarks versus Q&A sentiment, and whether management is still saying what it said last quarter. Live transcripts stream speaker-separated turns while the call is happening, with a finalized, cited transcript within minutes of the call ending.
Screening and discovery. A screener that takes plain English, so "profitable software companies with recent insider buying" returns a ranked list with reasons, plus thematic exploration and scenario modeling.
All of it runs on one data layer. From regulators: SEC filings, fundamentals, insider transactions, 13F holdings, congressional trades, short interest, and ETF and mutual fund holdings. From companies: earnings call transcripts, press releases, earnings slide decks, investor day presentations and fact sheets, pulled straight from investor relations sites. Slide decks are never filed with the SEC, which is why they are missing from most research tools.
Every figure links back to the document it came from, so anything the system tells you can be verified against the original. Data refreshes as companies file and report, so screens and alerts reflect what landed today rather than last quarter.
The same first-party corpus is available programmatically. A versioned REST API covers filings, fundamentals, KPIs, transcripts, IR documents, ownership, insider, congress and short interest. A read-only MCP endpoint lets AI agents such as Claude, Cursor and ChatGPT query KPI history, transcripts and IR documents mid-conversation with no connector to write. Keys are self-serve, with documentation and examples at docs.signals.ai.

Most people don't want to validate because if you validate it means you might invalidate your idea.
Most Founders Fail to Validate Because They Fear Killing Their Own Idea
Jordan argues that reluctance to validate is emotional, not strategic — founders protect the fantasy of being an entrepreneur more than they protect customers. The willingness to let an idea die publicly is what separates builders who ship from those who polish forever in private.
if you package it in a way that own that would only be interesting to people who already know who you are or already subscribed to you then you're doing the audience a disservice like by any new audience a disservice
Package for non-subscribers, not existing fans
Stop writing titles and thumbnails that only make sense to people who already follow you. Package for the stranger scrolling the home feed who has zero context on your brand — otherwise a life-changing video stays invisible. Clear, intriguing packaging is a service to the new viewer, not a betrayal of your authentic voice.
There's a play for whatever you're stuck on.
