What Sumble does in ChatGPT
The Sumble plugin helps sales teams research companies from ChatGPT. You can see which technologies a company uses and which roles it is hiring for, which often hints at what the company may need next and when it might be ready to buy.
It also finds professional contacts at those companies. You can ask to reveal an email or phone number, save accounts or people to lists, and generate a short brief on an account before reaching out, so research and list building happen together.
Results can be downloaded as CSV files for use in other tools, such as a CRM or a sequencing app. The plugin can also point you to Sumble's own product documentation when you have a question about how a feature works.
