retreat

Beta Acid tackled remote work's "quiet awkwardness" with a vibrant team retreat in São Paulo, Brazil. Twenty-six teammates from eight countries connected through shared cultural experiences rather than tasks.

This week of genuine, in-person moments transformed colleagues into friends, significantly boosting communication, collaboration, and trust.
