Shining Fingered dot moe is a company that's specialized in adult VR entertainment since 2069. Julianne Stingray has a subscription to Shining Fingered that costs her $800 a month. They are a sponsor of Streaming-chan.
The name of the company may be a reference to the anime "Mobile Fighter G Gundam", wherein "Shining Finger" is the ultimate attack of "Shining Gundam", the mecha piloted by the main protagonist. It may also be a reference to the visual novel "Steins;Gate", wherein one of the supporting characters, who happens to be a journalist, is nicknamed "Shining Finger" due to the speed at which she types on her phone.
