Authentication & Permissions
A tested starting point for authentication & permissions reduced repeated setup work.
We helped a B2B founder turn a broad product concept into a focused SaaS experience by defining user roles, core journeys, MVP priorities, navigation, interactive prototypes, and a reusable design system before development started.
Trusted by teams building ambitious products
A founder-led company with strong domain knowledge and a large list of product ideas but no clear MVP structure.
Coretus worked across product planning, UX, engineering, integrations, testing, deployment, and ongoing improvements.
Create a practical digital experience that solves the day-to-day business problem without adding unnecessary complexity.
A complete product-design foundation covering personas, feature priorities, information system design, key workflows, responsive screens, prototypes, and reusable components.
The founder knew the customer problem well, but the early feature list had grown quickly. Different user types needed different workflows, and it was unclear what had to be in the first release.
Starting development immediately would have increased cost and created avoidable rework. The team needed to make product decisions visible before writing code.
The first release included too many competing ideas.
Features are prioritized around the core value proposition.
Flows and navigation were still abstract.
The team can see exactly how users complete key tasks.
Engineering would need to make product decisions during implementation.
Reusable components and documented flows reduce ambiguity.
The first release focuses on the workflows most important for proving customer value.
Roles, navigation, dashboards, forms, and key states are designed as one connected experience.
Stakeholders can review and test the product experience before full development.
Tested foundations helped the team spend less time on setup and more time on the parts that made this product useful.
A tested starting point for authentication & permissions reduced repeated setup work.
Reusable work for product & integration layer let the team focus more time on the client’s specific needs.
This made it easier to add monitoring & reliability without rebuilding common foundations.
A tested starting point for notifications & feedback reduced repeated setup work.
A straightforward before-and-after view of what changed for the team and their customers.
The team knows what belongs in the first release and what can wait.
Product decisions become visible through flows and prototypes.
Engineering receives clearer workflows, components, states, and priorities.
The prototype gave us something much more useful than a feature list. We could actually see the product, challenge decisions, and simplify it before development .
