There's actually a funny story here, and one day we'll tell it in more detail.

TDLR: it's a coincidence / slightly obvious given our names. We discovered the similarity on the day we launched our logo, and it almost made us change our logo and/or company name XD

We have since met the getstream.io folks and had a good laugh about it together.
