Born in Denver, Built Globally
Our story starts in Denver, Colorado in 2023. Harris Kenny had been running Intro CRM, a marketing agency providing outbound and CRM services.
Intro CRM was a Smartlead expert, tiered HubSpot Solutions Partner, and one of the first Clay experts. We saw the need to get your data in your CRM.
As OutboundSync grew, we shut down the agency and spun out as a software company. Now, we help the most elite go to market teams route replies, attribute revenue, maintain block lists, and more.

Meet Harris Kenny

Harris Kenny is Founder and President of OutboundSync. He supports the team, develops the product, and drives OutboundSync's go to market motion—especially through its growth agency partners.
He has over 15 years of experience growing B2B companies. His favorite deal he ever closed was with a Fortune 150 steel company and required a pair of jeans. (Ask him about the story some time.)
Harris is especially proud of scaling a US-made 3D printer manufacturer from $1.7m to $20m in annual revenue. His sales experience led him to start Intro CRM, the agency that became OutboundSync.
