Technical Setup & Integration

CRM & Tool Integrations

Amplemarket connects natively with Salesforce, HubSpot, and other major CRMs. GTM tool integrations are managed via the Integrations panel in the app settings. Webhook-based and API-based sync keeps lead statuses, contact records, and sequence activity in sync bidirectionally.

Duo AI Onboarding (Knowledge Base Bootstrap)

On first sign-in, Duo performs an automated crawl of:

Your company website
Public web sources about your company
Your connected CRM (deals, contacts, accounts)

This builds a shared brand context — including competitor battle cards, persona definitions, value propositions, and objection-handling scripts — that all reps on the team share.

Signal Sources & Intent Data

Duo monitors a broad set of intent signals in near real-time:

LinkedIn/social activity (posts, comments, likes, connections)
G2 and review site activity (competitor reviews)
Slack community mentions
Website visitor identification
Job change alerts (prospect role changes)
Hiring signals (company job postings)
News and funding events
