Who it is for
Sales teams who want prospecting and follow-up handled in the same place they ask questions.
Seamless
Sales prospecting and outreach inside ChatGPT
Overview
What Seamless does
The app puts lead sourcing, outreach, and campaign management into a single ChatGPT conversation. The claim in the listing is consolidation: work that would normally sit in separate prospecting and sending tools is described as one continuous exchange.
The record gives little detail beyond that. It names no data sources, no contact record counts, no outreach channels, and no reporting features, so what is on offer is a scope rather than a feature list.
Category placement is Productivity, and the developer is a contacts data company. What the listing supports is the sequence it says it covers: find prospects, reach them, and run the campaign that follows.
What stands out
The listing claims an end-to-end pipeline in one conversation while leaving the mechanics unspecified.

Where Seamless is listed
Seamless is listed in the ChatGPT apps directory only. Seamless Contacts Inc. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
