He has a brother.
It's his real name.
There is very little personal information available about him.
On May 7, 2019, Guzu reached his 500 Twitch subscriber goal and celebrated by shaving all the hair off of his head. By May 17, 2019, he had reached 1,000 subscribers.
Guzu has recently acquired ~1,000 subscribers, which would earn him ~$2,500 USD per month if they are only tier 1 subscribers. This excludes any additional revenue from tips, Twitch cheer bit contributions, advertisements and sponsorships.
