Twitch will now represent Cloud9 and Team SoloMid in sponsorship sales negotiations, the streaming service announced on Friday.

Twitch is already the exclusive streaming partner for TSM and C9, and sponsors both organizations, but this partnerships moves Twitch into the teams' business practices. Twitch will now be responsible for selling "interested brands" on sponsoring TSM and C9.

"Twitch’s goal is to continually expand growth and revenue opportunities for our content creators, the true drivers of community creation,” Kevin Lin, COO of Twitch, stated in a press release.

“Our partnership with TSM and Cloud9 is long-standing and has helped pro players thrive in a growing live media ecosystem. This expanded partnership will also improve the overall health of the esports industry by providing more opportunities for players through long-term support in a more sustainable ecosystem.”

This is not the first time the streaming service has entered into direct business partnerships with esports teams outside of sponsoring them. In 2014, Twitch acquired GoodGame Agency, which owns Evil Geniuses and Alliance.

"We are excited to expand our relationship with Twitch to provide the best experience for viewers and players," Jack Etienne, Cloud9 CEO stated in the press release.

"Uniting Twitch’s media and our direct engagement will delight our clients and viewers in new and innovative ways. We’re eager to use these opportunities to create more value for our players and fans."
