I haven't found one but I can share some of my knowledge, and I am pretty sure these companies accept bitcoin, whether on the internet or in real life. I have used bitcoin on Reddit, Microsoft, ExpressVPN, Save the Children. Some other companies that I know of that accept bitcoin also include some selected Subway Stores, Webjet and Virgin Galactic.

After much digging I have found a website: https://99bitcoins.com/who-accepts-bitcoins-payment-companies-stores-take-bitcoins/
