Why co-op with Klaviyo?

  • Set up for Success: Before diving into individual teams and projects, all co-ops will complete Base Camp - Klaviyo’s week-long onboarding experience at our Boston HQ.  Base Camp provides focused time to learn about the ins and outs of Klaviyo, our product, and to get to know other co-ops. This robust first week ensures all co-ops join their teams fully prepared to dive into project work and make an immediate impact. 
  • Co-ops make an Impact: Our co-ops contribute to mission-critical projects for Klaviyo. No matter what team you join, you’ll be making a direct impact on our product and/or customers.
  • Our Boston Office is fun!: Co-ops stay fueled with free snacks and drinks, take breaks with each other over a game of ping pong or a round of golf in our simulator, and relax in our speakeasy (yes you read that right!).
