Reply.io is an AI-powered sales engagement platform built to automate and scale outbound outreach across email, LinkedIn, SMS, WhatsApp, and voice while preserving a personal touch. Teams can discover new prospects using Reply’s B2B database and Chrome extension, orchestrate multichannel sequences, manage replies in a unified inbox, and measure performance with detailed reporting. reply.io
Founded in 2014 by Oleg Campbell, Reply was created to eliminate repetitive, manual sales tasks like sending and following up on cold emails. The company has since evolved from a single-channel cold email tool into a full sales engagement platform with built-in AI capabilities, an email deliverability toolkit, and a growing ecosystem of CRM and workflow integrations. reply.io
In recent years, Reply has doubled down on AI with Jason, its AI SDR agent that can define ICPs, source prospects from a database of 1B+ contacts, personalize outreach, handle replies, and book meetings autonomously. This positions Reply between lightweight cold email tools and heavyweight enterprise engagement suites, offering sophisticated automation without the implementation overhead of classic enterprise platforms. reply.io
Headquartered in San Jose, California and operating as a fully distributed team across the U.S., Canada, and Ukraine, Reply serves primarily B2B organizations—especially SaaS companies, agencies, and growing sales teams. With 50–200 employees and thousands of customers worldwide, it is a well-established “OG” player in the sales engagement category that continues to modernize with AI, white-label options, and agency-focused functionality. linkedin.com
