Getting started
How Backchannels works
A guide to finding, filtering, and unlocking verified B2B buyers - covering filters, credits, saved searches, and the contacts table.
Overview
Quick start
- 01
Apply filters
Use the left sidebar to narrow contacts by location, company size, function, title, company, products purchased, or CRM status. Click Apply Filters when ready.
- 02
Browse results
The contacts table shows all matching contacts. Most fields are blurred until unlocked - you can preview name and basic company info before spending credits.
- 03
Select contacts
All matching contacts are pre-selected by default (up to 10,000). Use Quick Select in the toolbar to limit your selection, or click individual rows to toggle.
- 04
Unlock and export
Click Unlock Selected to reveal full details. Then export to HubSpot or Salesforce.
Filters
Search filters
The sidebar has 7 independent filters. Each is optional - combine them freely. Results update only after you click Apply Filters. The count shown beside each option reflects how many contacts carry that value.
Filter by country or continent. Selecting a continent (e.g. Europe) automatically includes all countries within it.
e.g. United States, Europe, Brazil
Select one or more employee-count brackets - useful for targeting SMBs, mid-market, or enterprise simultaneously.
e.g. 11–50, 51–200, 201–500
The department or business function. Great for finding Engineering, Marketing, Finance, or Operations personas at scale.
e.g. Engineering, Marketing, Sales
Specific job titles. Supports partial matching - 'Director' surfaces 'Director of Marketing', 'Sales Director', etc.
e.g. VP of Engineering, Head of Growth
Filter by specific company names when you know exactly which accounts to target.
e.g. Salesforce, HubSpot, Stripe
Find contacts who have reviewed or evaluated specific products. Signals active buying intent.
e.g. Salesforce CRM, Notion, Slack
Filter by whether a contact is already in your connected CRM. Helps you find net-new contacts only.
e.g. Not in CRM, HubSpot
Each filter card has its own Clear button. The sidebar header also shows Clear All whenever any filter is active. The sidebar can be fully collapsed to give you more table space.
Contacts
Unlocking contacts
What unlocking reveals
By default all contacts are locked - fields are blurred. Unlocking 1 contact costs 1 credit and reveals:
- Full name
- Email address
- Phone number
- LinkedIn profile URL
- Company details
- Products purchased
Selecting contacts
All matching contacts are pre-selected. Refine with:
- Quick select - Type a number in the toolbar - "50" selects the first 50.
- Individual toggle - Click any row or its checkbox to include or exclude it.
- Shift-click - Hold Shift and click to select a range of rows.
- Select All / Clear - Toolbar buttons for selecting everything or starting fresh.
After unlocking - export and sync
HubSpot auto-sync
If connected, contacts export to HubSpot automatically at the moment of unlock.
Salesforce auto-sync
Same for Salesforce. Duplicate prevention is applied on export.
My Contacts tab
All unlocked contacts are saved to your account and accessible from the Contacts tab.
Billing
Credits
1 credit = 1 contact unlocked
Credits are shared across your entire organization and deducted at the moment of unlock - not when browsing.
- If you don't have enough credits, a purchase dialog opens automatically.
- The sidebar shows your balance vs. contacts to unlock in a live summary.
- Purchase amounts round up to the next bulk tier for values above 10,000.

Workflow
Saved searches
Saved searches store a named snapshot of your current filters so you can reload them in one click. Perfect for recurring workflows - "EMEA SaaS Finance Leaders", "SMB Marketing Directors US", etc.
Interface
Contacts table
Available Contacts
All contacts matching your current filters. Most fields are blurred until unlocked.
Unlocked Contacts
Contacts your account has already unlocked. Toggle with "Show Unlocked" in the toolbar. Newly unlocked contacts are highlighted in green.
Best practices
Pro tips
Use continents for broad geo targeting
Selecting 'Europe' automatically includes all European country codes. Combine with a company size filter for a quick region + segment combo.
Save your ICP as a search
Build your ideal customer profile with filters, then save it. Reload it weekly to find new contacts added since your last run.
Check counts before applying filters
Every filter option shows a contact count. Use these to estimate list size before clicking Apply.
Quick-select before unlocking
All contacts are pre-selected by default. Use Quick Select to limit to 50 or 100 before unlocking to test list quality first.
Use CRM Status = Not in CRM
Surface only contacts you don't already have. Keeps prospecting focused on net-new buyers and avoids importing duplicates.
