# Integrations

> Connect CustomerOS to your existing tools

CustomerOS syncs data with your CRM, outreach tools, and ad platforms. All integrations use secure OAuth authentication and sync automatically.

## What Gets Synced

**CRMs** - Connect your CRM to sync customer and pipeline data

* [Salesforce](/integrations/crms/salesforce) - Bi-directional: Push qualified leads, sync opportunities, auto-update lead status
* [HubSpot](/integrations/crms/hubspot) - Inbound only: Import companies and deals into CustomerOS

**Outreach Tools** - Send qualified leads to prospecting platforms

* [Apollo](/integrations/outreach/apollo) - Outbound: Push CustomerOS qualified leads to Apollo for targeted outreach

**Meeting Schedulers** - Track buyer journeys leading up to meeting bookings

* [Calendly](/integrations/meetings/calendly) - Connect Calendly to track meeting bookings with buyer-journey analytics
* [HubSpot Meetings](/integrations/meetings/hubspot) - Connect HubSpot meeting links to track meetings and enrich with CustomerOS insights
* [Cal.com](/integrations/meetings/calcom) - Connect Cal.com to track bookings with full attribution (works with self-hosted instances)

**Meeting Intelligence** - Extract marketing insights from customer conversations automatically

* [Fathom](/integrations/meeting-transcripts/fathom) - Extract content ideas, messaging insights, and positioning opportunities from Fathom recordings
* [Grain](/integrations/meeting-transcripts/grain) - Extract buying committee language and persona-specific insights from Grain recordings

**Advertising Platforms** - Import campaign costs for attribution and ROI analysis

* [LinkedIn Ads](/integrations/ads/linkedin-ads) - Inbound only: Import B2B campaign costs, attribute leads via utm parameters

## Key Capabilities

**Centralized Intelligence** - All inbound data (HubSpot, Salesforce Accounts, ad campaigns) enriches CustomerOS leads with unified view

**Multi-Touch Attribution** - Track complete customer journey across Google Ads, LinkedIn Ads, website visits, and conversions using utm parameters and imported cost data

**Bi-Directional CRM Sync** - Salesforce opportunities and account status sync both ways; HubSpot data imports into CustomerOS

**Smart Domain Matching** - Automatically matches companies by domain across all platforms to prevent duplicates

**Automated Outbound** - Push qualified leads to sales tools (Apollo) and CRMs (Salesforce) based on ICP fit and stage

All integrations sync automatically after initial setup (every 2 hours to 15 minutes depending on platform).
