The Summer Sizzler is the Boston Interactive Media Association’s marquee summer bash, and the Camp BIMA edition leans all the way into the theme — a nostalgic summer-camp setup at the Washburn Pavilion at the Museum of Science, with an outdoor feel, playful activations, and a dress code that amounts to wearing your actual summer clothes.

BIMA is the Greater Boston Chamber’s network for the digital media and marketing world, so the crowd runs hundreds deep with people from agencies, brands, publishers, and ad-tech companies across New England. It’s equal parts reunion and business development: the industry’s annual chance to reconnect over food and drinks without a conference lanyard in sight. It reliably sells out, so plan ahead. If you work anywhere near Boston marketing or media, this is the summer night your whole feed will be at.
