K:BOS 2026 | Boston

The biggest wins weren't things people learned in a session. They were things they built afterward.

K:BOS 2026 is happening September 9–10 at the Hynes Convention Center in Boston, and if you're trying to decide whether it's worth the trip, the people to ask are the ones who were actually there last year.

We asked four Klaviyo customers what they walked away with from K:BOS 2025, and none of them led with the keynotes. They led with a flow that boosted repeat orders 5x, a new vendor picked up on the expo floor, and direct feedback sessions with the Klaviyo product team.
