Clearbit MCP Integration

Weldable's Clearbit MCP integration gives your AI agents access to real-time company and contact enrichment powered by over 250 public and proprietary data sources. Since HubSpot's acquisition of Clearbit in late 2023 and its evolution into Breeze Intelligence, the enrichment API remains one of the most reliable sources of firmographic and technographic data available. Weldable connects your agents to that data through natural language, so they can enrich records, qualify leads, and build audience segments without manual lookups.

Your agent can look up companies by domain, enrich contacts by email, and pull over 100 data points including company size, revenue, industry, tech stack, and social profiles. All of this happens in plain English, with Weldable handling API authentication and response parsing automatically.

Use cases

Real-time lead qualification

When a new signup hits your database, your agent immediately queries Clearbit with the user's email domain. It pulls back company revenue, employee count, industry, and funding status, then scores the lead against your ideal customer profile. High-scoring leads get routed to sales with full context. Low-scoring leads enter a self-serve nurture track. This happens in seconds, not hours.

CRM data hygiene at scale

Your agent scans your CRM for contacts and companies with missing or outdated fields. It batches these records, queries Clearbit for current data, and updates each record with fresh firmographic and demographic information. Run this weekly to keep your database accurate without anyone manually researching companies or updating spreadsheets.

Account-based marketing targeting

Your agent uses Clearbit's company lookup to identify accounts that match a specific profile: say, Series B SaaS companies with 50 to 200 employees in North America. It pulls matching companies, cross-references against your existing CRM to exclude current customers, and produces a target account list ready for your marketing team to act on.

Signup form enrichment

Instead of asking new users to fill in long forms with company details, your agent enriches the record as soon as the email address is submitted. Company name, size, industry, and location get populated automatically. This reduces form friction while giving your sales team the data they need from the very first interaction.

Competitive landscape mapping

Your agent queries Clearbit for companies using a specific technology or operating in a particular market segment. It compiles a list with key firmographic details, then writes the results to a Google Sheet for your strategy team to review. Run this quarterly to track how your competitive landscape shifts over time.

How it works

Connect your Clearbit account through Weldable's authentication flow. Your agent sends enrichment requests using email addresses or company domains, and Clearbit returns structured data in real time. Weldable handles the API key management and response formatting, so your agent works with clean, usable data from the first request.

Once connected, your agent can chain Clearbit enrichment with any other connected service. Look up a company in Clearbit, create a contact in HubSpot, and send an introductory email through Gmail, all in a single workflow triggered by natural language.

Tips

Enrich by domain for company data, by email for contacts. Clearbit's company API takes a domain name and returns firmographic data. The person API takes an email and returns individual details. Using the right endpoint for your use case improves match rates and avoids unnecessary API calls.

Cache enrichment results to reduce API usage. Clearbit charges per lookup on most plans. Have your agent check whether a record was already enriched recently before making a new API call. Store the enrichment date as a custom field so your workflows can skip records that are still fresh.

Combine with CRM writes for immediate value. Enrichment data sitting in an API response is not useful until it lands in your CRM. Always chain Clearbit lookups with a CRM update action so the data flows directly into the record your team works from.

Use tech stack data for segmentation. Clearbit returns the technologies a company uses. This is particularly useful for targeting: filter for companies running tools that complement or compete with your product to build highly relevant outreach lists.

Handle null responses gracefully. Not every domain or email returns a full data set. Your agent should check for missing fields and either skip the update or flag the record for manual review rather than overwriting good data with empty values.
