Currently, the other provider we have is PredictLeads which focuses on historical job descriptions to find mentions of tools.
However, there's likely a few more now in the market but we've not added them yet or in the process, although I've not gotten an update since they're not released. A few I know could return that information but they don't exclusively track that data as they focus on overall enrichment are tools like Ocean.io, Clearbit, Pitchbook, and a couple others.
If you have any others in mind you'd like to see added, we can check them out.
