ServiceGraph: The Ultimate Structured Directory of US Professional-Services Firms

In the era of automated workflows and intelligent assistants, access to high-quality, structured data is the difference between a successful operation and a manual bottleneck. ServiceGraph emerges as the definitive solution for those looking to stop scraping and start utilizing a refined, professional-services directory. As a structured catalog featuring over 100,000 US professional-services firms, ServiceGraph is specifically designed to be pluggable into any AI agent, providing a seamless bridge between complex queries and accurate business data.

Whether you are looking for legal experts, marketing agencies, or IT consultants, ServiceGraph offers a rich repository of information that goes far beyond simple search snippets. It provides a deep, multi-layered look at the service landscape in the United States, allowing procurement agents, sales teams, and developers to access information with unprecedented precision.

What's ServiceGraph?

ServiceGraph is a comprehensive, structured catalog of more than 100,000 US professional-services firms. This robust directory spans a wide range of industries, including law, marketing, consulting, accounting, IT, architecture, engineering, human resources (HR), public relations (PR), and design. Unlike traditional business directories that often provide unstructured or outdated information, ServiceGraph is built to be consumed by AI agents and automated systems.

At its core, ServiceGraph functions as an MCP server (Model Context Protocol) and an API-driven directory. It allows users to query specific firmographic data using structured filters rather than relying on unreliable keyword matching. From boutique law firms in California to mid-sized SEO agencies in New York, ServiceGraph delivers clean, classified data that is ready for immediate use in professional workflows.

Features of ServiceGraph

ServiceGraph stands out due to its commitment to providing real structured data rather than surface-level search snippets. Below are the core features that make this directory an essential tool for modern business intelligence:

1. Advanced Identity & Classification

ServiceGraph categorizes firms across 22 distinct industries. This is bolstered by a sophisticated multi-tag service taxonomy containing 89 specific tags. Each tag comes with an "evidence level" (low, medium, or high), ensuring that users understand the strength of a firm's expertise in a particular niche. Furthermore, ServiceGraph identifies the service model, distinguishing between multi-person firms, solo consultants, agencies, and nonprofits.

2. Precise Geographic and Size Data

Understanding the scale and reach of a firm is vital. ServiceGraph provides data on the geography served, categorized by city, multi-state, national US, or international reach. Additionally, it offers company size signals, such as solo, 2–10, 10–50, or 50+ employees, helping users find vendors that match their specific requirements.

3. Comprehensive Contact and Outreach Details

Every firm entry in the ServiceGraph directory includes essential outreach data. This includes:

• Primary phone numbers (filtered via US-NANP standards).
• Verified email addresses.
• Full physical addresses (street, city, state, and ZIP code).
• Website URLs and brand/legal names.
• Extensive social presence data, including LinkedIn, Twitter/X, Facebook, YouTube, GitHub, and TikTok.

4. Reputation and Review Aggregation

ServiceGraph acts as a central hub for reputation management. It aggregates client ratings and review counts from prominent third-party directories such as Clutch, G2, Capterra, Yelp, BBB, GoodFirms, TheManifest, and Trustpilot. It also tracks employer ratings from Glassdoor and Indeed, and monitors presence signals on Wikipedia, Crunchbase, and LinkedIn.

5. Engagement and Pricing Insights

Users can gauge a firm's market presence through LinkedIn follower counts and employee reporting. ServiceGraph also tracks Facebook engagement and vintage signals like the year the company was founded. Where available, the catalog includes pricing models, such as hourly rates, project-based fees, or tiered pricing.

ServiceGraph Use Cases

ServiceGraph is a versatile tool designed for several high-impact business scenarios:

Procurement Agents

Stop wasting hours on Google searches. ServiceGraph allows procurement professionals to shortlist vendors based on specific industry, service, location, and rating criteria. The structured filters ensure that you only see firms that meet your exact standards.

CRM Enrichment

If you already have a list of company domains, ServiceGraph can enrich your CRM. By passing a list of domains, the API returns classified industry information, service tags, and contact details in a single structured response. This "Bring-Your-Own-List" (BYO) functionality is a game-changer for data hygiene.

Sales Prospecting

Sales teams can build highly targeted prospect lists in seconds. For example, you can query for every IT consultancy in Texas that has a US-based engineering team and a high rating on Clutch. This level of granularity ensures that your sales outreach is directed at the most qualified leads.

FAQ

Do I need an API key to try ServiceGraph? No. Catalog discovery—including counts, breakdowns, and filter validation—is fully anonymous. Sign-in via email is only required when you need to access specific firm cards or contact bundles.

What does the free tier cover? The ServiceGraph free tier includes 200 unique firm-views per month on the /v1/search endpoint and 50 views on the /v1/get endpoint. No credit card is required to start.

How is the firm data sourced and updated? The catalog is built using public web data from firm websites, business registries, and third-party directories. Classification is performed using LLMs and is refreshed continuously. Stale data is removed to ensure the directory remains current.

Can I bring my own list of domains? Yes. You can hash any apex domain you have locally and call the /v1/get/:id endpoint directly. This allows you to enrich your existing data without performing a new search.

Is the data limited to the United States? Yes, for Version 1. ServiceGraph is currently scoped exclusively to US professional-services firms to maintain a focused and high-quality dataset. Other regions may be added in the future.

How is ServiceGraph different from a Google search? Google provides keyword-matched search snippets. ServiceGraph provides structured filters across 22 categories and 89 service tags. You get a clean, queryable list with verified ratings and size signals, rather than a list of search results that require manual re-ranking.

What happens if a firm is not in the catalog? If a firm is missing, the API returns a 404 (which is not charged against your quota). Coverage is currently at 100k+ firms and continues to grow. You can request specific firms to be indexed by contacting the ServiceGraph support team.
