What Firmable does in ChatGPT
The Firmable plugin brings Firmable's B2B sales data into ChatGPT. You describe the kind of company you want to sell to in plain English, and it builds a matching list of prospects, with verified emails and mobile numbers for the people who make buying decisions.
It also watches for signs that a company may be ready to buy: changes in roles and leadership, funding rounds, hiring surges and new technology. Searches can be narrowed by sector, headcount, location, the software a company uses and whether it is hiring. The listing says Firmable holds more than 15 million company profiles and 135 million contacts.
Firmable PTY LTD publishes the plugin. The Firmable service syncs both ways with Salesforce, HubSpot, Pipedrive and Microsoft Dynamics 365 to keep CRM records up to date as companies change. The listing also says Firmable is ISO 27001 certified and built around privacy-compliant data.
