Visuals by Impulse creates custom Twitch graphics including overlays, logos, emotes, alerts, and more. They have tons of free and premium options for streamrs.
VBI Rewards is their affiliate program. If you sign up for the program, you'll receive a personalized referral link. Share it on your channel and with friends, and everytime someone clicks your link and buys a product, you'll receive "pixels", which are points that you can redeem at a later time. You can use Pixels on premade stream overlays and graphics, or custom stream designs. No cash, though.

Visuals by Impulse also offers a sponsorship program, but it's invite only. If you want to become sponsored, you need to sign up for their affiliate program first. They monitor who is referring the most sales, and they'll reach out to influencers who are advocating VBI on their streams and social media.
