Create an API endpoint to measure company similarity against a list

We need to develop a new API endpoint that allows users to compare a given company (e.g., a new user’s company based on their email domain) against an existing list of companies (e.g., a list of clients). This will help users prioritize outreach by identifying companies that are highly similar to their existing clients.

🔹 Why?

• Helps qualify new leads by measuring how close they are to known clients.

• Enables automated prioritization in sales workflows.

• Allows users to upload a custom list and compare new companies dynamically.

🔹 How it works?

1. New API endpoint:

• Accepts a list of company domains (e.g., an uploaded client list).

• Accepts a single company domain (e.g., from a new sign-up).

2. Compute similarity score based on:

• Industry match

• Revenue and employee count proximity

• Technology stack overlap

• Geographic similarity

3. Return a similarity score (0-100%) and closest matches from the uploaded list:

{ "input_company": "newcompany.com", "similarity_score": 85, "closest_matches": [ { "domain": "existingclient1.com", "similarity": 92 }, { "domain": "existingclient2.com", "similarity": 88 } ] }

4. Integrate with lead scoring:

• Sales teams can prioritize follow-ups based on similarity.

• Can be used in automation workflows for high-intent leads.
