Baby Showers
Celebrate the new arrival with custom balloon décor designed around your theme — from soft boho neutrals to bold gender-reveal moments. We deliver, install, and clean up so you can stay focused on the celebration.
Explore Baby Showers →Birthdays
From first birthdays to milestone celebrations, we create show-stopping balloon arches, garlands, and giant number displays tailored to the guest of honor.
Explore Birthdays →Corporate
Make a professional impression at company and business events with balloon installations matched to your brand colors — perfect for grand openings, product launches, conferences, and office celebrations.
Explore Corporate →Holiday Party
Corporate holiday party balloon decor built for a room full of colleagues and a camera roll that ends up on LinkedIn — brand-matched balloon arches, entrance columns, and a photo wall people actually queue for. We load in around your venue’s schedule and strike the same night if the ballroom turns over.
Explore Holiday Party →Weddings
A wedding balloon garland is the most requested piece we build in the Bay Area — draped along a sweetheart table, framing a ceremony arch, or running the length of a reception bar. We design, install and remove it around your timeline, matched to your florals and color story.

Celebrate the graduate with balloon décor in their school colors — arches, garlands, class-year number displays, and photo backdrops ready for the big celebration.
Explore Graduations →Grand Openings
Draw a crowd to your launch with bold balloon columns, entrance arches, and ribbon-cutting displays designed to grab attention and match your brand.
