In our industry, our competition and adjacent tools are internal facing and not extremely well known.
They're not posted in job titles/ positions, and are internally focused, creating a lack of availability of data to use.
There are a ton of solutions out there that do this +more, so depending on the level complexity of insights you're looking for, it could be good, or leave you looking for more.
For my use case and my current industry, unfortunately it feel a little short.
That being said, if I were in marketing, adtech, etc with more information externally available, it'd be perfectly simple enough to get the job done.
At some point, someone will make a business out of getting real interaction/ surveying all the companies to update and catalog their tech stack beyond public facing info/ scraping. If HG Data goes that route.......
