“We’ve invited some of our favorite artists to participate in this kickoff event,” Sima Sistani, Houseparty CEO and co-founder, told Variety of the virtual bash.
“In the House” is free for all users of Houseparty, which has reportedly seen 17.2 million new installs across iOS and Android in recent weeks.
