TheirStack

Spot companies hiring for the roles you sell into, find who's using the tools you integrate with, and pull any company's full tech stack, all inside Deep Research.

BYOK, runs on your own keyGet your key

How it works

Connect your TheirStack key once in settings, then open SalesGPT and flip on Deep Research. From there just ask in plain language about who's hiring, what tech companies run, or a specific account's stack, and Deep Research reaches for TheirStack automatically whenever a request needs job-posting or technographic signal. You never touch a setting mid-chat.

What you can ask it to do

Find companies hiring for the roles you sell into

→“Which SaaS companies in the US have posted a VP of Sales job in the last 30 days?”

→“Show me fintechs actively hiring RevOps or sales ops people right now.”

Target accounts by the technology they already run

→“Find mid-market companies using Salesforce and Outreach that I can pitch.”

→“Which ecommerce brands are running Shopify Plus and Klaviyo?”

Look up any company's tech stack before a call

→“What technologies does Ramp use on their website?”

→“Pull the full tech stack for notion.so before my demo tomorrow.”

Search live job postings for buying signals

→“Show me job ads mentioning 'data warehouse migration' posted in the last two weeks.”

→“Find recent postings for 'implementation manager' at Series B startups.”

Connect your key

Grab your API key from your TheirStack dashboard.

Open Settings, Provider Keys in Fuse, find TheirStack, and paste it in.

That is it. Deep Research starts using TheirStack on your next request. Fuse encrypts the key and never exposes it to the agent.

Cost

TheirStack runs on your own key, so it spends your TheirStack credits, not Fuse credits.
