Use Case Recommendations
Best for: Extruct AI
Extruct AI is a company research API that answers structured questions about businesses, and its defining property is that every answer arrives with the source it came from. That constraint is what separates it from asking a general model about companies, where a plausible-sounding revenue figure or headcount may be a hallucination with no way to check it. Two data surfaces are searched: a curated index of roughly ten million companies, and the live web when the criteria go beyond what any index holds. The query interface is natural language against a compound specification — the site's own example asks for commercial HVAC contractors in Florida serving hospitals and school districts, with fifty or more employees, a completed $5M-plus project in the last twelve months, BIM/Revit capability, and active engineering hires — and returns candidates scored against each criterion individually, so a user can see which requirement eliminated which company. Three modes cover different jobs: semantic search for finding companies by description, lookalike search for expanding from a known set, and Deep Search for researching the live web against criteria no index anticipated. AI research tables let a user add arbitrary enriched columns across a result set, with email and phone lookups available at the higher tiers. Public Data Rooms hold indexed datasets that can be browsed free and exported on a paid plan, and API access plus a Chrome extension are included on every tier including the free one.
Ideal use cases:
- •Teams or individuals who need every returned answer carries its source, so claims are checkable rather than asserted
- •Teams or individuals who need curated 10m-company index plus live-web deep search for criteria no index holds
- •Teams or individuals who need compound natural-language criteria with per-criterion match scoring
- •Teams or individuals who need semantic search, lookalike expansion and ai research tables with arbitrary columns
- •Anyone focused on company-data workflows
- •Anyone focused on lead-research workflows
Best for: FilingFirehose
FilingFirehose is a JSON API over SEC EDGAR built around one specific insight: filers routinely bury material events under 8-K Item 8.01 ('Other Events'), where item-code-based monitoring misses them. The company published an analysis of 4,251 filings finding that roughly 7% of Item 8.01 filings contain misclassified material events, and the product's core work is body-text classification of every 8-K so cyber incidents, officer departures and material agreements surface regardless of how the filer coded them. Coverage extends to S-3 and 424B5 shelf takedowns and Schedule 13D/13G filings, which together make it a dilution- and ownership-tracking tool as much as a news feed. Alongside the API sit consumer-priced one-time products: a $9 Mini-Report giving a three-section AI summary of a ticker delivered in about five minutes, and a $49 Full Report running five sections of AI analysis with twelve months of context, real-data citations on every claim and a full refund if the ticker has no data. That refund promise is a meaningful signal in a category where thin coverage is usually discovered after payment. The product ladder is unusually wide for an indie tool — eight products off one pipeline, aimed at retail traders, small funds, lawyers, security teams and developers — and there is a founder lifetime deal that collapses the whole stack into one payment.
Ideal use cases:
- •Teams or individuals who need body-text classification of every 8-k, independent of filer item coding
- •Teams or individuals who need s-3 / 424b5 shelf takedown and schedule 13d/13g coverage
- •Teams or individuals who need json api with full archive access and webhooks
- •Teams or individuals who need one-time ai forensic reports on any us ticker with source citations
- •Anyone focused on sec-filings workflows
- •Anyone focused on api workflows
