Duo
by Amplemarket · San Francisco, USA · Founded 2018
AI copilot on a full outbound data platform
Overview
Amplemarket's advantage is that Duo sits on a mature outbound platform rather than being a thin agent wrapper. The underlying product already handles contact data, email validation, deliverability, multichannel sequencing and social selling, and Duo adds agents on top: buying-intent alerts, account research, AI-written sequences, and reply classification and handling. In practice that makes it a lower-risk purchase than the pure-play agents — if the AI underdelivers you still own a working sales engagement platform, which is not true of tools that are only an agent. Duo is closer to a strong copilot than an autonomous SDR, and Amplemarket is honest about that positioning. Pricing is quoted and typically lands between roughly $750 and $2,500 a month depending on seats and data volume.
Our verdict
The lowest-risk way to buy into AI outbound, because you are buying a proven sales engagement platform with agents attached rather than an agent with no platform underneath. Duo is a copilot, not an autonomous SDR — judge it on that basis and it is excellent value against the $3,750 pure-plays.
Best for
Sales teams that want one platform for data, sequencing and AI rather than stitching three vendors together.
Avoid if
You specifically want a hands-off autonomous agent with no rep involvement.
Pros
- Mature platform underneath the AI, so the purchase degrades gracefully
- Own contact data plus deliverability tooling included
- Materially cheaper than the autonomous pure-plays
Cons
- Copilot, not autonomous — reps still drive the motion
- Pricing still quote-based rather than self-serve
- Data coverage weaker outside North America and Western Europe
