2015Seamless Contacts: AI-powered sales automation software for B2B professionals, since 2014.
Seamless.AI operates a software platform that combines B2B contact and company data with outreach execution, organized into Data Engine, Engagement Hub, and Automation Network offering families.
The Data Engine supplies verified business email and mobile contact records together with buying-intent, job-change, and account-research signals. The Engagement Hub runs multi-step outbound activity across email, telephone, and social channels, while the Automation Network covers AI-assisted writing, programmatic API access, bulk credit pooling, and automated list building.
Seamless.AI presents one platform spanning contact data, outreach execution, and automation, which reduces the number of separate tools a revenue team must operate. Its published data surface includes a large verified-contact index, credit-back protection for invalid email addresses, and compliance certifications including SOC 2 Type II and ISO 27001.
The company also exposes programmatic API access across all subscription tiers rather than reserving it for higher plans. That combination of an integrated workflow surface and broad data access is the position it markets against standalone data providers on one side and standalone engagement tools on the other.
Seamless.AI competes in established categories on both sides of its product line. Contact-data providers such as ZoomInfo, Apollo, and Lusha are well-established alternatives for its data engine, while sales-engagement platforms such as Outreach and Salesloft already occupied the multi-channel sequencing space that its Connect product entered in 2026.
The company also operates under third-party platform constraints. Access to some prospect data depends on continued permissions from external platforms rather than on its own infrastructure, and its browser-extension workflow has been affected by restrictions those platforms have introduced.
