A Dumb Injury. A Brilliant Idea.
One busted shoulder (Brian's), a pile of soul-crushing medical bills, and a desperate need for cash—that’s how Frog Mustard was born. Did we turn to sensible side hustles? Absolutely not. We made bumper stickers—the loudest, most unhinged form of free speech.
Turns out, y’all love chaos just as much as we do. Now, we’re on a mission to slap premium, weatherproof weirdness on every car, laptop, and unsuspecting surface in the world.


Meet the Brains (and Beauty) Behind Frog Mustard
Alyssa: The chaotic genius behind the designs, branding, and world domination strategy. Seattle native, ADHD, and still has a grudge against that one person who said bumper stickers were outdated. Oh and Brian's fiancé.
Brian: The mastermind of magnets, king of cuts, and the glue that holds this sticker empire together. Grew up in Texas, loves a good road trip, and runs Frog Mustard full-time.
That's it. This is a two-man show, folks! So, be nice!
Science, But Make It Stick
We don’t just make stickers—we put them through absolute hell before they ever make it to your bumper. Over the past few years, we’ve tested, peeled, stuck, soaked, frozen, and sunburned more stickers than we can count—all in the name of finding the best damn materials on the market. If a sticker can’t survive rain, car washes, road trips, and questionable life choices, it doesn’t make the cut.
Every design is commercially printed using industry-leading materials, so your stickers and magnets stay vibrant, weatherproof, and road-ready. Every Frog Mustard product is designed for maximum longevity, impact, and stickability. Here’s what makes Frog Mustard the best in the game:
