Validate your product before you build it
High-fidelity prototypes that let you see, test and adjust the experience before a single line of code is written.
Design before code
Building without prototyping is expensive. Changing a screen in Figma costs minutes; changing it after it's been coded costs weeks. The prototype isn't decorative: it's the cheapest way to be wrong and course-correct.
At Tesler we design high-fidelity prototypes in Figma: navigable, with real states, microinteractions and data that mimic the finished product. Your team, your customers or your investors can use it as if it already existed.
The deliverable is useful to validate with users, align the team, pitch to investors and kick off development with zero ambiguity. Whether your tech team is internal or external, they receive a file ready to implement: components, variants, styles and specifications.
What we design
From idea to technical handoff, every deliverable is built to reduce risk and drive decisions backed by evidence.
-
Research & flows
User research, task mapping and user flows. The foundation everything else rests on.
-
Wireframes
Structure and information architecture before visual design. We validate logic before aesthetics.
-
High-fidelity prototypes
Finished screens, real interactions, error and loading states. Navigable like the final product.
-
User testing
Sessions with real users: observation, task-success metrics and actionable findings.
-
Product design system
Components, variants and tokens so the product scales without losing consistency.
-
Technical handoff
File ready for the dev team: specs, assets and behaviour documentation.
Projects we prototype
Mobile app
Full flows, microinteractions and real states.
SaaS web
Panels, dashboards and management flows for digital product.
Interactive landing
Navigable prototype to validate message and structure before the final site.
E-commerce checkout
Purchase flow tested with users before going to production.
Design system
Reusable components, tokens and documentation in Figma.
User testing
Guided sessions, metrics and actionable findings.
Dev handoff
File ready for your tech team to implement without questions.
Why prototype
The prototype is the smallest investment you can make to avoid the most expensive mistakes.
Less risk
Test the idea in hours, not months. If something doesn't work, you know before spending the dev budget.
Better conversion
Adjustments made on real usage evidence produce products that convert and retain better.
Aligned team
Everyone, from marketing to dev, sees the same thing. No more "I thought it worked like this".
Faster development
With the prototype ready, your dev team implements without stopping every other day to resolve design questions.
From hypothesis to navigable file
Research
We understand user, tasks and context of use. We define hypotheses to validate.
Wireframes
Structure and flows in low fidelity. We iterate fast on logic before visual design.
High fidelity
Visual design, components, states and microinteractions. Fully navigable prototype.
Testing & handoff
User testing, final adjustments and delivery ready for the dev team.
Frequently asked questions
What's the difference between a prototype and a mockup?
A mockup is a static image, like a photo of the product. A prototype is navigable: you can click, fill in forms, see errors and walk through flows as if it were real. It's the only honest way to validate before building.
Do you build the product after?
We focus on design. Development is handled by your internal team or the technical partner you choose. The prototype ships with all the documentation any developer needs to implement it without missing information.
I have an idea but I'm not sure it makes sense. Can I ask for just the prototype to validate?
That's exactly the ideal use case. We build the prototype, test it with potential users and hand you evidence to decide whether to move forward, pivot or drop it. The cost is a fraction of what it saves if the idea needs adjustments.
How long does a prototype take?
A prototyped landing ships in 1 to 2 weeks. A full app or SaaS flow takes 3 to 6 weeks depending on scope. Includes everything from research to documented handoff.
What exactly do you deliver?
Editable Figma file, navigable prototype with shareable link, component and state documentation, dev specifications and, if included, a user-testing report with findings and recommendations.
