What is Stample?
Stample is a flexible annual digital passport platform for creating passport-style experiences, scavenger hunts, sponsor challenges, food trails, corporate activities, tourism routes, and reward-based campaigns. Participants complete stops, scan codes, enter validation codes, upload photos, check in at locations, earn points, unlock badges, redeem offers, and complete challenges through a mobile app experience. You own your data, including the participant and engagement data collected through your campaign.
Scavenger Hunts
Create open-ended or ordered challenges with QR codes, clues, photos, or location checks.
Reward Programs
Unlock coupons, badges, offers, prizes, and sponsor rewards based on participation.
Engagement Reporting
See completions, redemptions, leaderboard activity, participant data, and campaign results.

How Stample Works
Create Your Experience
Build a passport, scavenger hunt, sponsor challenge, food trail, or reward campaign.
Add Stops & Rewards
Add locations, vendors, sponsors, checkpoints, questions, badges, coupons, and prize rules.
Participants Complete Stops
Participants download the app first, then scan QR codes, enter codes, take photos, check in by location, or complete challenges.
Track Results
Review completions, failures, redemptions, leaderboard activity, participant data, and reward activity.
Interactive Maps
Bring Every Stop to Life on the Map
Stample experiences can be paired with rich, interactive maps that help participants find stops, sponsors, vendors, landmarks, exhibits, restaurants, booths, or checkpoints. Grandstand maps can use native map pins, custom icons, branded pin styles, graphical overlays, and custom map artwork layered on top of native maps for an interactive map scavenger hunt app, restaurant week passport app, or tourism trail map app.
Custom Map Pins
Use branded pins, sponsor icons, category markers, or stop-specific visuals to make locations easier to find.
Native Map Support
Place Stample stops on native maps so participants can navigate real-world locations with familiar map behavior.
Graphic Map Overlays
Layer fairground maps, park maps, campus maps, downtown maps, or event artwork over native maps for a more visual experience.
Connected Stop Details
Link map locations directly to Stample stops, vendor pages, sponsor pages, schedules, lists, or reward details.

Participation Data
See which stops were completed, which offers were redeemed, and how participants moved through the experience.
Campaign Reporting

Choose the Stample Package That Fits Your Campaign
Start with a simple digital passport or build a full reward-based engagement program. Stample package pricing is annual, so your organization can use your selected package across multiple eligible events, campaigns, or seasonal activations during the year. You can try Stample for free or pay right away to begin your launch. Base package prices get your Stample experience published in the Stample mobile app on iOS and Android. Starting at $1,000, you can upgrade any package to a stand-alone app in the App Store.
