Give your team the first
end-to-end AI Sales Copilot
Amplemarket
Duo, Amplemarket’s AI Sales Copilot collaborates with each rep to help them sell like super reps.
It proactively tracks multiple buying signals, automates lead research, and generates personalized multichannel sequences with zero typing.
Duo handles the grunt work, from lead discovery to follow-ups, so your sales team can focus on what they do best: revenue generation.
Common Room gathers account and contact-level signals from multiple sources, merging everything from product usage and CRM data to social and community activity.
Robust buying signals with reliable contact data
Amplemarket
Duo, Amplemarket’s AI sales copilot, tracks multiple signals from diverse sources and delivers a frequently refreshed database with over 70 million updates every few weeks. Duo ensures accurate and comprehensive contact information, so no leads are missed.
Surfaces many signals but struggles with contact data. Applying filters like "primary email" drastically reduces usable contacts, excluding over 70% of leads. This requires users to integrate more data sources, increasing costs and complexity.
Multichannel sequences with intent-based hooks
Amplemarket
Duo automatically generates complete multichannel sequences with personalized hooks, such as company news, job changes, or LinkedIn activity. Duo enables outreach across email, LinkedIn, and creative channels like voice and video messages.
Roomie AI creates only first-touch emails, requiring manual edits and external tools (like Outreach or Salesloft) to run campaigns. Its single-channel focus limits outreach flexibility.
Automated LinkedIn prospecting and outreach
Amplemarket
Automates LinkedIn lead sourcing and outreach, including voice and video messages, for a creative and efficient approach to prospecting.
Offers LinkedIn plays via the Chrome extension. Unlike Duo, signal sourcing is manual, and execution requires additional tools; adding unnecessary effort.
Advanced deliverability solutions
Amplemarket
Ensures high deliverability with features like multi-domain/mailbox support, inbox placement tests, warmups, and mailbox rotation.
Lacks deliverability solutions, restricting users to data and signals without ensuring their outreach reaches the right inbox.
“Amplemarket has made the task of gaining trust with our prospects that much easier with its AI Copilot.”
Michael Connelly, Senior BDR at Stream.Security
