We make interactive experiences that engage and inspire.


Hidden Garden

Our first software, Hidden Garden, is an educational mobile game that turns real-world plant discovery into a playful adventure. The app is designed to help combat plant blindness.We believe learning about nature should be both fun and accessible, so we collaborate with botanical gardens to bring their collections to life through interactive quests and beautiful illustrations.

The Experience

  • The player receives a quest in the virtual book and is asked to find a plant in the garden.

  • The botanical illustration and playful clues are used to help identify the plant in the quest.

  • Using the map and via subtle geolocation hints such as "You’re getting closer...", the player is guided to the location of the specimen.

  • The player may snap a photo of any plant but it is only the one mentioned in the book that lets' the quest continue.

  • Once the plant has been found a reward is given - a glowing seed!


Tailored for every garden

  • Each botanical garden we collaborate with has a tailored edition of Hidden Garden.

  • The featured species are selected from the garden's unique flora.

  • Clues and drawings are tailored for layout and education goals.

  • The interactive map of the garden works as a helpful tool for the visitor.

Early Partner Invitation

We’re currently opening a limited number of collaborations for early partner gardens who wish to co-shape the next development phase of Hidden Garden.Join as an early adopter and help shape the future of Hidden Garden.
We’ll co-develop your own edition and you decide its value after launch.


Process

  • Define the scope
    Together we outline your edition - the species to feature, educational objectives, and any new game features to be developed.

  • Development & content creation
    We handle the heavy lifting: software implementation, art, writing, and integration. You’re welcome to review content continuously as it’s created.

  • Testing & delivery
    Once the tailored version is complete, you’ll receive a preview for internal testing and feedback before launch.

  • Launch & communication
    Your edition of Hidden Garden goes live.
    Minteract provides branded materials such as posters, roll-up designs, and digital graphics to help you promote the experience locally.
    The Garden leads its on-site communication, while Minteract can coordinate digital promotion and shared storytelling through social media and newsletters.

  • Transparent work report
    A document is provided detailing the total hours delivered and how they were spent (software development, content creation, implementation).

  • Value review
    Within one month after delivery, you review the experience and decide what you feel it’s worth. Based on your assessment, we issue the invoice. The payment schedule can be adapted to your budget cycle (for example, your next fiscal year).

  • Seasonal content (optional)
    Before each new season, you can choose to add new content helping attract return visits and keeping your edition fresh.

  • Maintenance & renewal
    Maintenance is included for one year (hosting, software updates, bug fixing).
    After that, you can choose to renew. The renewal fee is shared equally among all gardens using Hidden Garden.
    Example: if total annual maintenance costs for Minteract are €2,000 and 5 gardens are active, each pays €400. The amount is recalculated at each renewal. The renewal fee is capped at maximum €800/garden.


Why we do this

This model allows us to collaborate closely with pioneering institutions while ensuring transparency and fairness.It also helps us understand how Hidden Garden creates value in different contexts in this early phase of the project, from public facing to university level education.

If you’re interested in becoming one of our early partners, we’d love to hear from you.Contact: [email protected]


Visitor Donations
– 100% to the Garden

The app can include gentle, optional donation prompts for visitors who wish to give back. These are shown to the player when completing quests or after completing a session.Even small contributions can add up to something meaningful.We see this as more than a product, it's a way to help your garden grow.


How it works

It's a Platform
One app, many experiences. The visitors only requires one app to engage with many different experiences. We have developed tools to handle the complexity.
Smart Location Detection
The app automatically detects which garden the visitor is in and loads the corresponding edition of the game.
Lightweight & Efficient
All content is dynamically loaded from the cloud, keeping the app fast and lightweight with minimal storage requirements.
Accurate Species Recognition
We integrate PlantNet, a leading plant identification model, to help recognize species from visitor photos.
Continuous Quest Optimization
We track anonymously how visitors engage with each quest and fine-tune the difficulty, ensuring the experience stays fun, rewarding, and just the right level of challenging.
