Is there a way to find *all* possible domains related to a specific company based on details like: legal name, alias, parent company, regional branches, etc

Hey [user] - Thanks so much for sharing!! Taking a look now. I am getting an error when trying to access the playbook in Notion. I tried both my personal and work emails to access and it is saying You don't have permission to access this page.Could you open up access for me? Thanks!

Hey, Yes, this is doable in Clay. The typical approach is to use Claygent together with HG Insights to map out company hierarchies and associated domains. Claygent can research the company using inputs like legal name, aliases, parent company, and regional presence, then return related domains. HG Insights helps validate and enrich that data at scale. Here’s a playbook that walks through the exact setup: notion.so And here’s a ready to use template you can clone: app.clay.com Let me know if you have more questions.

Steps to Implement 1. Import accounts from your CRM with company name, location, and domain 2. Use Normalize Company Domain to standardize domain variations and focus on the primary domain for each entity. 3. Gather hierarchy data from 1. Hit Horizons (EMEA-specifc) 2. HG Insights 3. Claygent 1. Aggregate and deduplicate using a Claude reasoning prompts to combine results from all providers into a single corporate hierarchy (make sure to dedupe). 1. Output will consist of three subarrays for the input company, parent companies, and subsidiaries. 2. This will return the level of each company in the overall hierarchy (L1, L2, etc…) 1. Normalize entity information with a separate AI prompt to standardize addresses, tax structures, legal names, and corporate identifiers across all entities. 2. Extract the level, legal structure, HQ address, domain, and normalized name of the input company. 3. Use formulas to extract the same information for the immediate parent, global parent, and immediate children. 4. Determine if you want to map the relationship from the input company to the immediate parent company or the global parent company. 1. Perform a lookup into the company to extract the account ID. 1. Update the input company with the associated level and map over the account ID of the immediate/global parent to the system field “Parent Company” (SFDC only).
