& Solutions

Problem

Statement

E-shop customers are skeptical of vague “green” claims.

Brands often lack the verified proof behind those claims in the form of third-party certificates, etc.

Even when proof is provided, it is either too technical, too shallow, or doesn’t have visually engaging storytelling.

Design UI Features, Decisions & Impact

Claim Verification & Display

Sustainable brands need a fast, guided way to prepare and get their sustainability claims verified — and have them displayed transparently on webpages of their products. That means a clear way of associating claims with products and understanding the requirements for the proof documentation that needs to be uploaded to substantiate claims.

Add Claim

Browse and quickly find relevant claims through search & filters.

Define Submission

Select claim level and see clear requirements for proof.

Document Upload

Attach certificates/reports, add context for customers.

Link Products

Bulk-select products to connect with verified claims.

Track Status

Monitor submissions, validity, and approvals in one place

Link Products

Track Status

Monitor submissions, validity, and approvals in one place

Clients can submit a new claim in under 10 minutes — from selection to submission.

Time-saving features like submission duplication and product reassignment reduce repetitive work, especially for similar submissions or renewals of expiring ones.

The process eliminates to the maximum extent the need for support requests.

The Widget behaviour in desktop and mobile browsers displaying sustainability claims

Approved claims appear instantly in the product e-shop widget with description, document proof, and a blockchain record. One of key design decisions made: introduction of multiple widget sizes (S, M, L), giving brands flexibility between a compact, layout-friendly embed and a larger, context-rich preview. It is optimized for desktop & mobile views.

Customers understand sustainability claims instantly, without needing to read PDFs or search elsewhere. Having the proof at hands, claims can inform the customer at more conscious shopping decisions.

Various widget sizes and layouts ensure seamless integration with different e-shop designs.

Scalability and consistency: clients can reuse widgets across products and e-shops, and Gratitude branding conveys trust among e-shop customers.

Feature 2

Price & Supply Chain

Transparency

Brands often struggle to present their product journey and cost breakdown in a way that’s both trustworthy and easy to digest for customers.

With Gratitude clients can define Price Transparency (PT) and Supply Chain Transparency (SCT) for each product. These two modules are closely linked in both UX and logic — and are designed to make data input intuitive and updates efficient even for non-technical users.

PT - Define Cost Categories

Select or create categories that reflect product pricing.

PT - Specify Cost Breakdown

Assign percentages and reorder for clear widget display.

SCT - Set Supply Chain Steps

Use pre-selected defaults or add custom steps to map the journey.

SCT - Add Step Details

Upload documents, locations, and multiple items without clutter.

PT - Define Cost Categories

Select or create categories that reflect product pricing.

PT - Specify Cost Breakdown

Assign percentages and reorder for clear widget display.

SCT - Set Supply Chain Steps

Use pre-selected defaults or add custom steps to map the journey.

SCT - Add Step Details

Upload documents, locations, and multiple items without clutter.

Re-using the filled-out forms as templates - massive time saver.

Automatic data validation eliminates user errors.

The interface patterns for both features are similar. That sped up the development of the platform, and users save time by going through familiar workflows.

Price Transparency: Customers instantly see where their money goes with a pie chart graph and percentage breakdown with additional descriptions.

Traceable Journeys: Every step from raw materials to distribution is on display — complete with names, origins, suppliers, document & links. In case of large number of items or large chunks of information, these are collapsed and can be instantly viewed by expanding.

Visual breakdowns of price and supply chain make complex data digestible in seconds.

Presentation Configurator & QR-Code Stories

Product packaging have limited space — they can only fit short labels or certification logos, leaving most sustainability data unseen. For brands that invest heavily in transparency, this means their efforts are often hidden.

By adding a product-specific QR code that opens an interactive, mobile-friendly presentation, shoppers can quickly see the full picture: where the product came from, how it was made, and why it’s a better choice. In a store, that extra context can be one of deciding factors that drives a purchase.

Select Products

Choose which products will share the same story.

Define Story Structure

Start with pre-selected sections in logical order, reorder if needed.

Customize Content

Add text and media per section with live mobile preview.

Generate QR Code

Instantly create a product-specific QR-code linking to the story.

Generate QR Code

Effortless Storytelling: Non-designers can create engaging, mobile-ready product stories in under 10 minutes (layout is already pre-defined and most of the data pre-fetched).

Visual Brand Consistency: Pre-built templates ensure a unified brand voice across all product presentations, without losing flexibility for minor adjustments.

Reduced Marketing Workload: Instead of spending a lot of time on custom solutions, brands can use our tool and save the time for their business activities.

The QR-code product presentation in action (demonstration)

The customer scans QR-code and an intuitive Instagram-like story opens: splash intro, product/brand story, video explaining the product/brand, a list of claims with details on expand, product’s price and supply chain breakdown. At the end of the journey user can leave feedback by rating the experience and share the story.

The interface is adaptable to any modern smartphone layout: from largest iPhones to smallest 320px iPhone SE.

Customers scan and an have an instant access into the product story without downloads or logins.

The whole story can be watched within a minute or five, depending on content. The smooth transitions, familiarity of Instagram-like experience and value of information keep the user engaged.

Presentations have the room for new future features such as life-cycle assessment, product care tips, or related product highlights, as well as more visual customisation.

Measuring Success

Important Note

In October 2025 Gratitude Co. faced funding constraints, the primary project was put on pause.

Important Note

In October 2025 Gratitude Co. faced funding constraints, the primary project was put on pause.

Although formal analytics tools weren’t implemented during the MVP stage, the platform was designed with clear points for measuring adoption and impact:

17 sec — average time customers spent interacting with the widget (early engagement metric);
Widget engagement rate — % of product page visitors in e-shop who opened the widget;
QR scan rate — number of customers scanning product QR-codes in-store;
Feedback review — how many customers found the widget / presentation experiences valuable or not valuable, and how many does not give any feedback at all.
Proof document open rate — measuring trust-building behavior;
Feature adoption — 8 early clients integrated Claims, PT, and/or SCT; 2 also prepared QR presentations (though not yet rolled out on packaging).

These metrics would guide product iteration, highlight ROI for clients, and validate the platform’s role in influencing sustainable purchasing behavior.
