Outbound integration specialists for HubSpot and Salesforce
We built OutboundSync because outbound data shouldn't live in five different tools. It belongs in your CRM. Agencies and GTM teams use us to route replies, attribute revenue, and keep block lists in sync.

Our story
Born in Denver, built globally
We started in Denver in 2023. Harris Kenny had been running Intro CRM, an outbound and CRM agency—Smartlead expert, HubSpot Solutions Partner, and early Clay partner. We saw the need to get outbound data into the CRM.
OutboundSync grew; we shut down the agency and spun out as a software company. Today we help elite go-to-market teams route replies, attribute revenue, and maintain block lists from their CRM.
Featured on Startups for the Rest of Us
TinySeed Tales S5 followed Harris’s journey. August–September 2025.
Our founder
Meet Harris Kenny
Harris Kenny is Founder and President of OutboundSync. He leads the team, product, and go-to-market—especially through agency partners.
He has 15+ years growing B2B companies. He’s proud of scaling a US 3D printer manufacturer from $1.7M to $20M revenue; that sales experience led to Intro CRM, the agency that became OutboundSync. (His favorite deal involved a Fortune 150 steel company and a pair of jeans—ask him.)
