Amplemarket is an all-in-one sales platform combining a B2B contact database, multichannel outreach sequences across email, phone and social, deliverability optimization, and Duo, an AI sales copilot that watches for buying signals such as a decision-maker visiting a company’s website, a closed-lost prospect resurfacing, or someone commenting on a competitor’s post. Duo builds a model of a company’s ideal customers from its website, CRM and past deals, drafts personalized multichannel sequences including AI-written emails and Duo Voice messages recorded in a rep’s own cloned voice, and learns from a rep’s feedback over time. Founded in 2018 and headquartered in San Francisco, the company states thousands of teams have migrated to it from tools including Apollo, Outreach, ZoomInfo and Salesloft, backed by customer case studies citing results such as a 56 percent cut in tooling costs after consolidating onto the platform.
Duo Voice sends AI voice messages in a cloned version of the sales rep’s own voice, which is a materially different, lower-risk use of voice cloning than impersonating someone else, but a team using it should still disclose that outreach messages are AI-generated where relevant, since a cold prospect cannot otherwise tell. As with any AI-scored intent and signal system, Amplemarket’s buying-signal detection is a probabilistic prioritization tool, not a guarantee that a flagged signal will convert, so reps should still apply their own judgment before acting on it.
Startup is $600 a month on an annual term, including 2 users, 27,000 contacts, multichannel sequences, AI intent signals and Duo Copilot.
