Backed by $7M in funding, the new toy balances AI tech with hands-on play—turning kids’ wild ideas into printable, colorable stickers
A Playful Take on AI: Meet Stickerbox
Stickerbox, developed by Brooklyn-based startup Hapiko, is a voice-activated AI sticker printer for kids—and it’s winning over skeptical parents and curious young minds alike.
- At $99.99, the toy includes the printer, three rolls of sticker paper (180 stickers), a power cable, and colored pencils.
- Instead of screens and apps, kids press a button, say their idea, and receive a printed sticker version of their imagination—ready to color and stick anywhere.
What seemed like a novelty gadget turns out to be a thoughtful blend of creativity, technology, and hands-on play.
Surprisingly Engaging and Balanced
Despite initial doubts about an AI toy replacing imagination, real-world testing showed Stickerbox can enhance it rather than diminish it.
- It transforms voice prompts into simple, black-and-white line art, ideal for coloring.
- Promotes creative exploration without screen time, balancing the quick fun of AI with the calm focus of coloring.
- The thermal printer needs no ink, and the paper is BPS- and BPA-free, making it safe for kids.
Stickerbox taps into a child’s innate curiosity and mirrors the delight of a coloring book that listens.
A Toy That Grows With Kids
Stickerbox’s AI is surprisingly good at interpreting open-ended prompts—especially valuable since children often describe things in nonlinear, imaginative ways.
- From “a tiger eating ice cream” to “a lizard riding a skateboard,” the AI adapts with playful accuracy.
- Complex, meandering prompts are parsed with ease—no need for kids to be “prompt engineers.”
This makes it ideal for a broad age range, growing alongside kids’ prompting and creative skills.
Built for Safety—and Surprise
Hapiko built custom AI guardrails into Stickerbox to keep it age-appropriate and safe:
- It filters out violent, sexual, or profane prompts.
- Inappropriate requests return whimsical or unrelated results, deterring misuse without scolding.
Kids quickly learn the most rewarding results come from imaginative prompts, not shock value.
“We want to be the trusted brand for parents,” said co-founder Arun Gupta, “where you don’t have to look over your kid’s shoulder.”
The Minds Behind the Box
Hapiko was co-founded by Arun Gupta (former CEO of Grailed) and Bob Whitney, who led engineering at The New York Times Games division and Anthropic.
- Whitney’s inspiration came from his own child: when his son asked for a tiger coloring page, he turned to ChatGPT and printed it.
- The pure joy his son showed sparked the idea: “He just had this look on his face—pure magic.”
They realized that no one was designing AI specifically for kids, and set out to build something that celebrates imagination while staying safe and accessible.
Regular Updates and a Growing Ecosystem
Stickerbox is Wi-Fi-connected, enabling frequent firmware updates and the addition of new features.
- Upcoming companion app will allow kids to save their creations, view sticker history, and could host premium features in the future.
- The device is also designed to evolve, with new filters and prompts regularly improving creativity guidance.
- Refills are affordable—$5.99 for 3 rolls, and six rolls are included in a current promotion.
While Hapiko earns revenue from device sales, its business model is focused on accessibility and repeat play, not excessive upsells.
