Digitising a Sustainable Lifestyle Platform for a Stockholm-Based Health and Wellbeing Company

At a glance
SustainChange, a Stockholm-based company focused on sustainable lifestyle practices and proactive occupational health, had an established evidence-based model for individual and organisational change. The model worked. Scaling it required a digital product. Tarento ran a six-week LEAD sprint followed by a continuous discovery process to define, prototype, and validate a full-platform solution for both B2C and B2B markets. The output fed directly into development, resulting in iOS and Android apps, a corporate portal for team-level engagement, and an administration portal for user and licence management.
About the project: from a manual model to a scalable digital platform
SustainChange helps individuals and teams build lasting habits in areas including work environment, mental wellbeing, absence management, and workplace conflict. The company's approach is grounded in years of research and practice. It produces measurable improvements in wellbeing, cognitive ability, and productivity. The challenge was not the model itself. It was that the model existed as a manual process, delivered through direct engagement rather than through a product.
The company needed a digital platform capable of serving both individual users in the B2C market and companies managing team-level adoption in the B2B market. These are distinct contexts with different access requirements, different interaction models, and different needs for administration and oversight. A single platform had to accommodate both without compromising either.
The challenge: designing a digital product for a process that had never been a product
The brief carried three constraints that shaped the entire design and discovery process:
- The underlying model had to be faithfully translated into a digital experience, preserving what made it effective while making it intuitive enough for users who had never encountered it before.
- The platform had to be designed for acquisition as well as retention. New users and organisations needed a clear path in, not just a useful experience once they arrived.
- The solution had to serve B2C users interacting as individuals and B2B users engaging through their organisations, with distinct portals and management structures for each.

Why Tarento: structured product discovery for complex, first-generation digital products
Products like SustainChange's, where an expert process is being translated into a digital experience for the first time, carry inherent risk. The domain knowledge sits with the client. The design and technology decisions sit with the delivery partner. Without a structured discovery process to bridge them, the risk is building something that is technically functional but experientially wrong.
Tarento's LEAD framework was the right fit for this reason. It brings Lean and Design Thinking together within an Agile delivery structure, reducing the risk of building in the wrong direction before validation has been done. For a first-generation product with both B2C and B2B requirements, that structure was not optional.

What Tarento delivered
Six-week LEAD sprint and continuous discovery:
- Stakeholder and end-user interviews to surface the full range of needs, constraints, and behavioural patterns across both markets
- Six LEAD workshops combining structured ideation with rapid prototyping and team alignment
- User testing and validation to confirm that the proposed experience matched how target users actually think and navigate
- MoSCoW analysis and feature audits to establish a clear, prioritised scope
Actionable design and architecture artefacts for development teams:
- Mobile application design and strategy for iOS and Android
- Visual design prototype for the web platform
- Techno-functional roadmap defining the full product build sequence
- Functional requirements and user story maps structured for immediate development handover
- Technical architecture direction covering the system design for the complete platform
The discovery and design phase was structured so that development teams could take up the work without ambiguity. Artefacts were built for enablement, not for documentation.
Technology and platform scope
The platform was designed across three distinct environments. The mobile application addressed individual users on iOS and Android. The corporate portal served companies and teams managing sustainable practice adoption across their workforce. The administration portal handled user management, organisational structure, and licence administration.
Each environment required its own interaction model and access logic, all built on a shared platform architecture defined during the LEAD sprint.
Impact: a product in market with positive reception from the target user base
The LEAD sprint and discovery process gave the development teams what they needed to move into implementation without prolonged back-and-forth on requirements or scope. Releases followed at pace.
The iOS and Android applications received positive feedback from the target user base following launch. The corporate portal enabled team-level adoption at company scale, extending the platform's reach beyond individual users into the B2B market the company had been targeting. The administration portal gave SustainChange the operational control needed to manage users, organisations, and licences as the customer base grew.
The digital platform took a manual, expert-led process and made it accessible, scalable, and self-service, without losing the rigour that had made the original model effective.
Why this case study matters
Translating a research-backed behavioural model into a consumer and enterprise digital product is one of the harder product design challenges. The domain expertise is not transferable to a delivery team through a requirements document. It has to be surfaced through structured discovery, tested with real users, and resolved into design decisions before a line of production code is written.
Tarento's LEAD framework exists precisely for this type of engagement, where the problem is well understood by the client but has never been expressed as a digital product. The same approach applies to health tech, edtech, professional services, and any domain where expert knowledge needs to be made accessible at scale through software.
