Crunchbase enrichment seems like the biggest waste of $$$ ever if youre not doing anything time sensitive with funding signals. All that data is in Linkedin pages/news
You can try using bloomberry.com to find companies that use Grafana. They specialize in enterprise tech detection unlike builtwith. Other options include: TheirStack (which uses job postings data) and scraping Indeed/Linkedin Jobs for companies that mention these technologies
What competitor of urs are you interested in ? If its something thats frontend based, Builtwith probably does the job well. If its backend focused, then bloomberry.com is a good alternative. HG Insights too although I hear thats fairly expensive
