Use TheirStack in Fuse to:
Search job ads
Find companies hiring for a role or using a technology
List a company’s tech stack with firmographic filters
No setup needed. Fuse runs TheirStack on its own account and bills each successful step to your credit balance.
Describe what you need to Fuse Deep Research in plain language. The agent decides when to call TheirStack, in what order, and how to combine the results.
Optional: to use your own TheirStack key instead, open Settings → Provider Keys in the Fuse app (workspace owners and admins), add the key and save. Fuse checks it straight away, and your key is only used for your own runs.
