Jem and the Holograms turns 41 this year —
and we're throwing the most outrageous celebration this fandom has ever seen.
JemCon is the only fan convention in the world dedicated to Jem and the Holograms, and we've been bringing this community together for 21 years across 14 states and 3 countries. This September, we're expecting 200+ attendees for a full weekend of voice actor appearances, a drag show, rock fashion runway competition, cosplay pageant, charity auction, panels, vendors, and more.
We're looking for brand partners who want to get in front of a passionate, highly engaged audience of adult collectors, creatives, and pop-culture fans who take what they love seriously.
We have four sponsorship tiers — there's something for every budget and every brand.
Frequently Asked Questions
-
No, donations to JemCon 2026 are not tax-deductible. We're a fan-run convention, not a registered nonprofit organization. Your donation goes directly toward making this the most glamorous, glitter-filled weekend the Jem fandom has ever seen—think of it as investing in pure nostalgia and community magic rather than a tax write-off.
-
Your donation helps us bring the truly outrageous to life! Funds support travel and accommodations for talent and guests, venue costs, AV equipment for panels and performances, extra events like drag shows and dance parties, swag bags and exclusive merch for attendees, and all the glitter, sequins, and stage production that makes JemCon feel like a real rock concert experience.
We're keeping this intimate (vs. massive commercial cons), so every dollar directly impacts the weekend's magic.
-
Hell yes! We're always looking for passionate Jem fans to join our various committees. We've got teams working on everything from the fashion show and cosplay contest to the pool party, vendor coordination, yearbook creation, and more. Check out our Volunteer page if you want to help make the magic happen. No experience necessary—just bring your love for the franchise and your "truly outrageous" energy!
-
Absolutely! If you're a vendor, artist, or creator who wants to contribute items for swag bags, the charity auction, or contest prizes instead of cash, we'd love to talk. We're especially interested in Jem-themed artwork, vintage dolls or merchandise, handmade items, or services like graphic design or photography. Email us at jemconforever@gmail.com with what you'd like to contribute.
-
Yes! We'd be honored to recognize donations made in someone's name. Whether it's honoring a fellow Jem fan, remembering someone who loved the show, or celebrating a friend who shares your obsession with Synergy and holographic earrings, let us know when you donate and we'll include an acknowledgment in our convention program/yearbook.
