Five-day design sprint
Map, sketch, decide, prototype, and test with 5 users, so the core idea is proven within one week.
For founders and product teams turning an idea into a web or mobile product: a tested prototype first, then one design system your developers can build, from $1,250.

Teams we have built for:








The Problem
Products designed one screen at a time look finished in Figma and fall apart in development, when nobody can say what happens between the screens.
01 · Screen by screen
Screens were designed one at a time, with no shared system.
Every screen comes from one component library shared by web and mobile.
02 · Missing states
Developers ask what happens when a payment fails.
Flows cover errors, empty accounts, and edge cases before visual design begins.
03 · Two products
The mobile app looks like a different product.
Shared design tokens keep colors, type, and spacing identical across platforms.
04 · Moving dates
Every design gap becomes a meeting and a delay.
A developer reviews each screen, so gaps surface during design instead of mid-sprint.
You have a product idea, a feature list, and a folder of competitor screenshots. A freelancer turned them into polished screens, one at a time. Then development started, and the questions arrived: what happens when a payment fails, what does a brand-new account see, where do settings live? The mobile app got designed later by someone else and looks like a different product. Every gap became a meeting, and the launch date moved twice.
We start with a 5-day design sprint that turns the idea into a tested prototype before anyone designs final screens. Then we map every flow, design the interface as one system for web and mobile, and keep a developer in each review to cost what we draw. You launch a product that was designed as a whole, not assembled screen by screen.
Five days to a tested idea
A design sprint ends with 5 real users trying a clickable prototype of your core flow.
One system for web and mobile
Shared components and tokens keep your web app and mobile app looking like the same product.
Developers cost every idea
A developer sits in design reviews, so expensive features get flagged before anyone falls in love with them.
Our Digital Product Design Process
You approve the sprint goal, the flows, and the visual direction before each phase starts, and a developer checks every screen before handoff.
We talk through your idea, users, business model, and anything already designed or built. You get a sprint plan, the questions it will answer, and a fixed price, or a note that a cheaper first step fits better.
What's Included
Each engagement takes your product from a sprint-tested idea to a documented design system, with the flows, screens, and specs your developers need to build it.
Compare Options
A freelancer can be cheaper for a handful of screens, and a large agency brings bigger teams for enterprise programs. Here's how a digital product design company like ours compares.

|---|---|---|---|
| Discovery | Five-day sprint with user tests | Usually skipped | Multi-week strategy phase |
| Platforms | Web and mobile in one system | Often one platform | Web and mobile |
| Developer input | Developer in every review | Rarely involved | Separate engineering team |
| Usability testing | Included in every plan | Extra cost | Included, often larger studies |
| Design system | Figma components and tokens | Ad hoc styles | Full system, longer timeline |
| First prototype | Tested within 5 days | Depends on availability | Often several weeks |
| Build option | Same team can build it | Design only | Separate build contract |
| Cost | Fixed price from $1,250 | Lower hourly rates | Higher monthly retainers |

What Our Clients Say
Feedback from teams we have designed and built websites and apps for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
A product design partner should make your build cheaper and your launch calmer. These habits keep design decisions tied to users, budgets, and code.
We put a rough prototype in front of users before designing final screens. Polishing an idea nobody wants means paying for the same design work twice.
Every component we draw maps to something your developers can build with standard libraries. Custom interactions come with their cost, so you choose them on purpose.
iOS screens follow Apple's Human Interface Guidelines and Android screens follow Material Design. Users get patterns they already know on both platforms.
If a no-code tool or a template covers your first version, we'll tell you before we quote. A smaller first release often teaches you more than a big one.
Pages, components, and variables are named so a new designer can find their way on day one. You aren't tied to us for every future change.
Figma files, prototypes, test recordings, and the design system belong to you at handoff. Take them to any developer or keep building with us.

Good fit
Founders with a new product idea
You have a product idea and a budget for version one, and you want it tested with users before a single screen gets polished.
Product teams adding a mobile app
Your web app works, and now you need iOS and Android apps that feel like the same product, not a separate project.
Startups after a stalled launch
Your first version launched and stalled, and you need a digital product design consultancy to rethink the product, not just repaint it.
Companies comparing design firms
You're comparing each digital product design firm on your list and want digital product design and development handled by one team.
Agencies selling app projects
Your agency sells apps to clients but needs a product design agency that works under your brand on discovery and interface design.
Not a fit
Physical product design
You're designing a physical product, such as furniture or a consumer device. An industrial design firm is the right partner, because we design software only.
Redesigning a few screens
You have a live product and only need specific screens or flows improved. Our UI/UX Design Services page covers focused redesigns of existing products.
Designs already finished
Your designs are finished and tested, and you only need them turned into code. Our Figma to Code Services page covers that build step.
Budget under $1,250
Your budget is under $1,250 for all design work. A paid UI kit and a few sessions with a freelance designer will get a first version on screen.

Projects at DeveloperLook start at $1,250 for a 5-day design sprint with a tested prototype. Designing one platform with up to 30 screens starts at $3,600, and web plus iOS and Android designs start at $6,900. The price depends on platforms, screens, and user roles, and the quote is fixed after a free product call.
A design sprint takes 1 week. Designing one platform takes another 4 to 6 weeks, and web plus mobile takes 8 to 12 weeks in total. The biggest factor is feedback speed, so we ask for one decision maker on your side who can approve flows and screens within 2 business days.
It's the work of turning a software idea into a product people can use, covering research, user flows, interface design, prototyping, and testing. The product here is digital: a web app, SaaS platform, or mobile app. Industrial design of physical goods is a separate field, handled by different firms.
UX design decides how a digital product works: which steps a user takes, what each screen asks for, and what happens when something goes wrong. Visual design makes it look right, but UX determines whether people finish what they came to do. In our projects, UX work comes first and covers every user role.
Because design mistakes are cheapest to fix before code exists. A confusing flow costs a Figma edit during design and a sprint of rework after launch. Good product design also gives developers a complete picture, which cuts the back-and-forth that often delays a first release.
Choose one that tests ideas with users, shows how its designs became shipped products, and can explain what each feature costs to build. Ask to see a design system from a past project. A design partner that can't discuss engineering trade-offs will hand you screens that are expensive to build.
Look for a clear process, real user testing, and designers who work closely with developers. Check that past projects cover web and mobile if you need both, and that files are organized enough for another team to pick up. Fixed pricing per phase is a good sign, because it shows the team has scoped similar work before.
Evaluate it against user outcomes first: can people complete key tasks, and how quickly? Then check consistency across screens, accessibility basics such as contrast and focus states, and whether developers can build it without guessing. We use usability tests and a design review checklist, so the verdict doesn't come down to taste.
A design sprint compresses weeks of debate into 5 days: map the problem, sketch solutions, decide, prototype, and test with 5 users. The format comes from Google Ventures and the book Sprint by Jake Knapp. You end the week knowing whether the core idea works, before development money is spent.
User-centered design improves engagement by fitting the product into routines users already have. It builds around what they do and need, rather than asking them to change. That means shorter onboarding, clearer next steps, and features people come back to. Testing each version with real users keeps the team honest about what works.
