ServiceGraph

ServiceGraph is a powerful, structured B2B firm directory designed specifically for AI agents, eliminating the need for manual web scraping. It provides a comprehensive catalog of over 100,000 US professional-services firms across various sectors, including law, marketing, consulting, accounting, IT, architecture, engineering, HR, PR, and design. This service is easily pluggable into any AI agent as a one-line skill install, supporting a wide range of popular agents such as Claude Code, Codex, Cursor, GitHub Copilot, Gemini, and many more.

The platform offers a free tier, requiring no credit card to get started, and provides access to its API console, documentation, and OpenAPI specification for seamless integration. ServiceGraph transforms complex natural language queries into precise, structured data requests, delivering highly relevant results. For instance, an agent can process a request like "Find me three boutique IP law firms in California that handle patent prosecution for hardware startups" and return a curated list of firms with their websites, contact information, and aggregated ratings.

ServiceGraph caters to several key use cases:

• Procurement Agents: Enables AI agents to efficiently find and shortlist vendors based on specific criteria such as industry, service, location, size, and third-party ratings, offering a superior alternative to generic search engines.
• CRM Enrichment: Allows users to pass a list of company domains and receive classified industry, services, and contact information in a structured format, enhancing existing CRM data.
• Sales Prospecting: Facilitates the rapid creation of targeted sales lists, for example, identifying "every IT consultancy in Texas with at least one US-based engineer team and a third-party rating."

The data provided for each firm is rich and highly structured, moving beyond simple search snippets:

• Identity & Classification: Includes industry categorization across 22 types, a multi-tag service taxonomy with 89 tags (each with an evidence level), service model (e.g., multi-person firm, agency), geography served (city, multi-state, national US, international), and company size signals (solo, 2-10, 10-50, 50+).
• Contact & Outreach: Offers primary phone numbers, email addresses, full physical addresses, website URLs, brand and legal names, and social media presence across platforms like LinkedIn, Twitter/X, Facebook, YouTube, GitHub, and TikTok.
• Reviews & Reputation: Features aggregated client ratings and total review counts from various third-party directories (Clutch, G2, Capterra, Yelp, BBB, GoodFirms, TheManifest, Trustpilot), along with employer ratings from Glassdoor and Indeed. It also indicates presence on Wikipedia, Crunchbase, and LinkedIn.
• Engagement & Pricing: Provides LinkedIn followers and employee counts, Facebook engagement metrics, founding year, and published pricing models or ranges (hourly, project, tiered, quote-on-request).

The catalog is built from continuously refreshed public web data, including firm websites, third-party directories, and public business registries. Classification of industry, services, size, and geography is performed using LLMs and re-checked on updates, ensuring data freshness and accuracy. ServiceGraph is currently focused on US professional-services firms, with other regions planned for future development. Its core advantage lies in offering structured filters and precise data, enabling AI agents to deliver actionable insights and curated lists, rather than just a stream of search results.
