The hard part is not finding numbers. It is figuring out which numbers actually belong in the same conversation.
Sticker Mule looks like the biggest sticker-focused brand in this group, but the public estimates do not all measure the same thing. Similarweb publishes estimated company revenue bands and traffic. Grips publishes estimated online-store sales. And in StickerGiant’s case, ColoradoBiz gives a company-level sales quote that is more useful than a narrow web-store snapshot. So the honest version is this: Sticker Mule still looks like the scale leader, StickerApp and StickerYou form the next serious tier, StickerGiant and MakeStickers sit below that, and CustomStickers.com looks more like a roughly $10 million traffic-based estimate than a public, sourced revenue figure.
If I had to give one clean answer as of April 2026, I would say Sticker Mule is probably a low-nine-figure sticker specialist, not a mid-eight-figure one. That matters because it separates Sticker Mule from most of the direct custom sticker field. The next band looks more like mid-eight figures, where StickerApp and StickerYou both have a real case. Then you get into the low-to-high $20 million zone where StickerGiant and MakeStickers make more sense, depending on whether you mean company sales or online-store GMV. And then you have newer or smaller players like CustomStickers.com, where a roughly $10 million estimate can make sense as a directional read based on traffic and market position.
The Working Revenue Ladder
Here is the practical ranking I would use right now:
- Sticker Mule: roughly $100 million to $200 million, based on Similarweb’s company profile, plus a much larger traffic footprint than the rest of the specialist sticker field.
- StickerApp: about $43.8 million in 2025 online-store sales, with strong current revenue and session data from Grips.
- CustomStickers: around $10-15 million as a traffic-based directional estimate, not a public revenue disclosure.
- StickerYou: best treated as $25 million to $50 million, not $15 million, based on Similarweb’s revenue band, 434.8K visits, and Grips showing $22.2 million in 2025 online-store sales.
- StickerGiant: best framed around the high $20 millions on a company-sales basis, even though Grips puts current online-store GMV much lower.
- MakeStickers: roughly $20 million to $25 million, with Grips estimating $20.7 million in 2025 online-store sales.
- YouStickers: roughly $1 million to $5 million, in 2025 online-store sales. It is a new but growing player in the market.
Why These Numbers Conflict So Much
This is the part people usually skip, and it is the reason these revenue articles often come out wrong.
Similarweb’s public company profiles show things like annual revenue bands, category rank, and total visits, and the pages clearly note that the traffic data is estimated. Grips, by contrast, is labeling its number as annual sales on the online store, which is a GMV-style ecommerce figure rather than a clean company-wide revenue statement. Those can point in the same direction, but they are not identical.
StickerApp is the easiest example. Similarweb’s public profile for StickerApp shows an annual revenue band of $2 million to $5 million, while Grips shows $43.8 million in 2025 online-store sales and more than $4.4 million in January 2026 online sales alone. Those numbers do not fit together neatly, which is exactly why you should not pull one figure from one site and another figure from another site and pretend they are all the same metric.
StickerGiant shows the same problem from a different angle. Grips says the web store did $10.3 million in 2025 online-store sales. But ColoradoBiz quoted StickerGiant’s CEO in late 2019 saying the company expected to be just under $30 million in sales the next year, and that about 60 percent of sales were coming from labels. That makes StickerGiant look much more like a broader label-and-sticker business than a sticker-only web checkout number would suggest.
Sticker Mule Still Looks Like the Clear Scale Leader
Sticker Mule is still the easiest brand to put at the top.
Similarweb currently lists Sticker Mule at $100 million to $200 million in annual revenue, with 2.1 million total visits in March 2026 and a #6 U.S. category rank in Printing & Self Publishing. That is a much bigger traffic footprint than the other sticker specialists in this discussion, and it is the cleanest public signal that Sticker Mule is operating in a larger scale band.
Then there is Sticker Mule’s own volume data. Its public stats page shows more than 6.26 million die-cut sticker orders, nearly 2 million circle sticker orders, more than 1.5 million custom sticker sample orders, and more than 1.4 million custom t-shirt orders. That is not a revenue statement, but it does reinforce the same basic conclusion: Sticker Mule is not just slightly ahead. It is running at a very large operational scale for a specialist print brand.
That is why I would not overcomplicate the top of the ranking. If the question is “Who looks biggest?” the answer is still Sticker Mule. The real debate starts below that.
StickerYou Is Clearly Bigger Than a $15 Million Read
This is one of the biggest fixes from the earlier version.
StickerYou’s Similarweb profile shows a company revenue band of $25 million to $50 million, a 2008 founding year, 434.8K visits in March 2026, and a #43 U.S. category rank in Printing & Self Publishing. That is not what a $15 million sticker business usually looks like in the public data.
Grips also estimates $22.2 million in 2025 online-store sales for StickerYou. On StickerApp’s January 2026 competitor view, Grips shows StickerYou at roughly $1.5 million in January revenue and about 411.5K sessions, which lines up pretty well with the broader Similarweb traffic picture. So the better way to frame StickerYou is low-to-mid eight figures, not the mid-teens.
In plain English, StickerYou belongs in the serious competitor group. It may not be as big as Sticker Mule, but it is also not some minor second-tier outlier that can be hand-waved away with a $15 million estimate.
StickerApp Has a Strong Case for the Next Spot
StickerApp is where the source mismatch gets weird, but the overall scale signal is still strong.
Grips estimates StickerApp at $43.8 million in 2025 online-store sales, with $4.4 million in January 2026 revenue, about 338.2K sessions in that same month, and a note that it leads the immediate competitor set in revenue. Similarweb also shows 379.1K visits and a #35 U.S. category rank in March 2026.
The reason StickerApp is hard to place is that Similarweb’s company profile gives it a much lower annual revenue band than Grips does. But if you look at the live commerce signal rather than the profile label alone, StickerApp clearly behaves like a large ecommerce business. So for a practical comparison article, I would treat StickerApp as a mid-eight-figure competitor, and in a web-sales discussion it may be the clearest challenger below Sticker Mule.
StickerGiant Looks Bigger Than Its Web Store Alone
StickerGiant is the company most likely to be misread if you only use one number.
ColoradoBiz quoted CEO John Fischer saying StickerGiant expected to be just under $30 million in sales, while also noting that about 60 percent of sales had shifted to product labels. That matters because it shows StickerGiant was already more than just a sticker storefront.
Grips, meanwhile, estimates $10.3 million in 2025 online-store sales for stickergiant.com. That is useful, but it should be read as a narrower storefront number, not a full company valuation or a complete company revenue figure. So when someone says StickerGiant is around $30 million, that sounds much more reasonable than reducing the whole business to a $10.3 million website metric.
That is why ColoradoBiz is the better anchor here. It is closer to the question the reader actually cares about: “How big is this company?” not just “How much did this website sell?”
MakeStickers Looks Like a Low-To-Mid $20 Million Competitor
MakeStickers lands in a cleaner spot.
Grips estimates $20.7 million in 2025 online-store sales for MakeStickers. Similarweb also shows 198K visits in March 2026, which is meaningfully smaller than StickerYou or StickerApp but still large enough to support a real mid-market position.
So if you want a simple working number, about $20 million to $25 million is a fair way to frame MakeStickers. It is not operating at Sticker Mule scale, but it is clearly not tiny either.
Where CustomStickers.com Fits
CustomStickers.com belongs in the article, but it needs different wording.
The basis for that inference is simple. Similarweb comparator pages consistently place CustomStickers.com well below Sticker Mule, StickerYou, and StickerApp in category position, and well below the traffic footprints we can see for Sticker Mule, StickerYou, StickerApp, and MakeStickers. In other words, it looks clearly smaller than the $20 million to $40 million group, but not so small that it should be ignored. That makes roughly $10 million a fair directional place to put it if the goal is a market map, not an audited financial statement.
And that is really the right way to write it. CustomStickers.com is a smaller player than the top sticker specialists, but it is not invisible. It looks more like an emerging competitor than a market leader. It is growing very quickly based on traffic metrics.
The Real Takeaway
If you want the cleanest version of this article, here it is.
Sticker Mule still looks like the revenue leader among sticker-first brands. StickerApp and StickerYou form the next meaningful band, with the exact order depending on whether you care more about online-store GMV or broader company estimates. StickerGiant belongs in the next cluster down, but it should be judged as a broader label-and-sticker company, not just by its current web-store sales. MakeStickers fits in the low-to-mid $20 million range. And CustomStickers.com makes the most sense as a smaller, traffic-based estimate around $10 million rather than a public, sourced revenue number.
That is not as tidy as a fake-precise ranking, but it is more useful. And for private companies, useful usually beats neat.
FAQs
Is Sticker Mule Definitely the Biggest?
Based on the public signals available right now, it looks like the answer is yes among sticker-first specialists. Similarweb places Sticker Mule at $100 million to $200 million in annual revenue with 2.1 million visits, and Sticker Mule’s own stats page shows a much larger order base than the rest of the direct sticker field. But because these are private companies, “definitely” is still too strong if you mean audited public proof.
Why Do Sticker Revenue Estimates Disagree So Much?
Because the sources are often measuring different things. Similarweb publishes company profile estimates and traffic data, while Grips publishes online-store GMV and live commerce metrics. Those can point in the same direction, but they are not the same number.
