For me it's amazing how much more performant software can be when you can just serialize and load data from disk using something like recordio or leveldb.
I noticed that you are returning the company name in the title. https://logo.clearbit.com/fb.com .Is that intentional? Asking this because you provide a Company API too which is paid.
This API call is just returning a PNG image with almost no EXIF data. In that case, the title is set by browsers to the filename, which is equal to the domain name itself. Are you seeing something else in the title? (I see fb.com)
