Who it is for
Sales and marketing teams researching named accounts before outreach or territory planning.
Overview
What Sumble does
Sumble is a research source covering how target accounts are organized: team structures, reporting lines, the technologies in use, and projects that appear to be under way.
Searches can be framed by technology, headcount, location, or job function, and the answers get at questions such as which group inside a company runs a particular tool and who is likely to sign off on a purchase. Open job postings are treated as evidence of active work.
Results can be collected into account and contact lists, and organizations can be filled out with detail on what they have adopted. The record positions it for territory mapping, call preparation, and list building.
What stands out
The angle is internal structure and technology adoption rather than contact details alone.

Where Sumble is listed
Sumble, Inc ships this on both marketplaces: Sumble is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain.
Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

Claude listing
In the Claude connectors directory
Sumble publishes 23 tools to Claude, deeper than 74% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Sales & Marketing publishes 18, so this one runs 5 tools above its bucket's median and ranks 39th of 94 by tool count.
It falls in the 21-50 tools band, which holds 20% of the Claude directory.
Sumble publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.
