Reverse lookup is one of the most valuable use cases for product-led growth and inbound-heavy teams. Most product companies:
  • Ask only for an email at signup
  • Want to keep onboarding friction low
  • Enrich the user after signup to understand who they are
Bitscale enables this by letting you reverse-enrich a user starting from just an email address.

​
When to Use Reverse Lookup

This workflow is commonly used by:
  • Product-led SaaS companies
  • Freemium tools
  • Trial-based platforms
  • Inbound motion teams
  • Growth and lifecycle teams
Typical goals:
  • Identify the user’s role and seniority
  • Understand their company and ICP fit
  • Personalize onboarding or sales follow-ups
  • Route leads to the right workflow or team

​
Supported Inputs

Bitscale supports reverse lookup from:
  • Work emails (most common in B2B)
  • Personal emails (Gmail, Outlook, etc.)
You can route emails automatically based on domain type.

​
Step 1: Start with an Email Column

Create or ingest a grid that contains an inbound email column. This can come from:
  • Signup events (via webhook)
  • CSV imports
  • Product analytics tools
  • CRM syncs
Before running enrichment, add simple conditions:
  • If email does not contain:
    • gmail
    • outlook
    • yahoo
    • other personal ESPs
      → Treat as work email
  • Else → Treat as personal email
This improves match accuracy and avoids wasted credits.

​
Step 3: Find LinkedIn Profile from Email

Bitscale provides two dedicated enrichments:
  • Find LinkedIn via Work Email
  • Find LinkedIn via Personal Email

​
Why LinkedIn is the key output

Once you have a LinkedIn URL:
  • Most people-level enrichments unlock
  • Accuracy increases significantly
  • Downstream workflows become reliable
Map the inbound email to the correct enrichment and run it.

​
Step 4: Enrich the Person Using LinkedIn

After retrieving the LinkedIn URL:
  1. Add it as a column
  2. Run Enrich Person
  3. Bitscale scrapes and structures:
    • Name
    • Current role
    • Company
    • Seniority
    • Skills
    • Experience
    • Summary
This gives you a full profile from a single email.

​
Step 5: Expand the Workflow (Optional)

Once the person is enriched, you can:
  • Find phone numbers
  • Enrich the company
  • Run Bit Agent to infer:
    • ICP fit
    • Use case
    • Industry relevance
  • Push data to:
    • CRM
    • Sales tools
    • Lifecycle automation
    • Slack alerts
All from a single email input.

​
Common Product Use Cases

  • Lead scoring at signup
  • Sales-assisted onboarding
  • Trial-to-paid routing
  • Account-based personalization
  • Founder / decision-maker detection
  • Enterprise signal detection from inbound signups

​
Best Practices

  • Always aim to resolve a LinkedIn URL first
  • Use conditional routing for personal vs work emails
  • Treat reverse lookup as the entry point, not the final step
  • Layer company enrichment and AI classification for best results
