Using Paid Enterprise AI Tools as Intent Signals for ICP Filtering in B2B Sales

hey everyone. has anyone tried sourcing companies that use a paid/enterprise version of chatgpt or claude (not just personal use) as an intent signal? trying to see if this is something we can layer into ICP filtering for a client. curious if HG insights or any other enrichment source actually tracks this specifically, or if anyone's found a workaround that's actually accurate. Thanks in advance for the feedback!
