The Company Directory provides a window into a massive global database of businesses, powered by TheCompaniesAPI (TCA). It serves as your primary tool for manual TAM building and targeted account research.

​
Core Capabilities

Global Search

Search millions of companies by domain, name, industry, employee count, or revenue bracket.

Watchlists

Add interesting companies to a personal Watchlist without cluttering your main active Account pipeline.

Instant Promotion

Promote a directory listing directly to a first-class SignalArk Account with one click.

Industry Classification

Use AI to automatically classify uncategorized companies into your specific taxonomy.

​
Bulk Promotion & Preview

When you find a segment of companies that fit your ICP (e.g., “SaaS companies in London with 50-200 employees”), you can use the Bulk Promote feature. Before any credits are consumed, the UI provides a detailed Preview showing exactly how many companies will be imported, how many already exist in your workspace, and the total credit cost for the required enrichment.

​
YC Company Import

The directory includes special tags and filters for Y Combinator alumni, allowing you to easily build targeted lists of highly-funded, fast-growing startups based on their batch year and sector.
