The Knowledge Base

Flatstudio is a full-cycle engineering design unit based in Lisbon, Portugal and Ukraine. We design, build, and evolve digital products for SaaS, Fintech, Sports Tech, iGaming, MedTech, Govtech, Web3, News & Media, Travel, Commerce, and Corporate companies worldwide. We combine product design, UX/UI, web app engineering and brand strategy in one team.

A traditional agency delivers visuals. An Engineering Design Unit delivers outcomes. We combine UX/UI design, product engineering, and strategic thinking — not as separate services, but as one team that stays accountable through the entire product cycle: from diagnosing the problem to shipping the solution.

Flatstudio works across a wide range of industries: SaaS, Fintech, Sports Tech, iGaming, MedTech, Govtech, Web3, News & Media, Travel, Commerce, and Corporate products. We build systems designed for high-load, regulated, and fast-scaling environments.

Flatstudio offers services across product and interface design, web app engineering with React and Webflow, brand identity, and marketing design assets. These services are delivered through five core solutions: Product Audit and Discovery, Fundraising and Concept for pre-seed founders, Post-MVP Evolution for growing startups, Rebuild Rebrand Reignite for legacy products, and Dedicated Product Team for ongoing collaboration. In short, Flatstudio is a full-cycle partner for product design, development, and long-term product evolution.

Flatstudio operates from Lisbon, Portugal, serving clients globally across Europe, the US, the UK, Asia, Africa, and beyond.

The first step is a discovery call where we learn about your product stage, goals, and challenges. You can reach us via the Contact page.

It depends on scope. A product audit takes 2 to 3 weeks. A full redesign typically runs 6 to 12 weeks. Dedicated team engagement is ongoing and scales with your product needs.

Iron-clad. Every single team member signs a strict NDA before onboarding. We work with Fintech and Medtech, so data security is our default setting, not an extra feature.

Absolutely. If you need exclusivity in your niche, we respect it. We are here to build your advantage, not leak it to the market.

Both. For startups, we are an agency (Sprint mode). For giants, we are a dedicated unit that integrates into your Slack and Jira (Embedded mode).

We don't just send Figma links. You get a component-based system, documented tokens (variables), and a video guide explaining every decision to your dev team.

Depends on the chaos level. Fixed price for clear targets (MVPs). Retainer for ongoing product evolution. We hate surprise bills as much as you do.

Figma and Webflow are our primary tools for product and web design, but our engineering team also works with React, Vue.js and 3D/WebGL where needed. We design with implementation in mind, so every screen, component and animation can be translated into production code without guesswork.

Yes. We frequently handle end‑to‑end transformations: brand strategy, visual identity, product interface redesign, design system rollout and implementation in Webflow or custom frontend stacks. For mature SaaS, Fintech, betting and GovTech products we focus on reducing design debt without breaking existing users, SEO or internal workflows.

We always start with clarity, not guesswork. First, we schedule a short discovery call to understand your product stage, goals, constraints, and what “success” means in real numbers. Based on that, we map you to the right solution — from Fundraising Concept to Product Audit or a full Rebuild — then set up NDA and shared workspace so our team plugs directly into yours.

We do both. Our team builds scalable Webflow sites and custom React/Vue.js applications with clean, modular architecture. That includes technical SEO basics, performance, secure backend integration and design hand‑off that engineers can implement without guessing. Many clients work with us for product design and keep us as their long‑term dev and Webflow partner.

Product & Interface Design focuses on the core experience of your product: mobile and web apps, enterprise dashboards, internal platforms, design systems and UX audits. Marketing Design covers landing pages, social systems and ad creatives that drive acquisition and campaigns. Product design optimises how existing users work inside the product; marketing design brings them in, explains your value, and turns attention into sign‑ups and revenue.

We work with B2B and B2C SaaS, Fintech, GovTech, Sports Tech and iGaming products. Most of our clients are startups and scale‑ups with complex logic, high‑load dashboards, internal tools or betting products that need a consistent design and engineering partner rather than a one‑off creative studio.

Flatstudio is an engineering design unit that covers the full stack of digital product work: product & interface design, brand identity & strategy, web app engineering (Webflow and custom React/Vue.js), and marketing design assets. All services are built as one modular system so design, code, and communications stay aligned as your product scales.

Both. Our clients range from early-stage founders raising their first round to enterprise teams scaling complex platforms with millions of users.

Clients consistently highlight three things: deep industry knowledge, logical and scalable design systems, and honest communication. We challenge weak decisions early rather than executing them blindly.

SaaS products require scalable dashboards, clear information hierarchy, and enterprise-grade design systems. iGaming demands real-time data visualization, emotional engagement design, and geo-compliance. We have dedicated case studies and proven patterns for both. For SaaS, we design subscription dashboards, admin consoles and internal automation tools. For iGaming, we focus on odds display, betslip flows, live data feeds and geo‑compliant onboarding.

Yes. For Outlier we delivered a 20% conversion rate from free to paid users, reaching 1,000+ paid subscribers at $20/mo in six weeks with zero advertising. For RG we built a platform that secured 70+ media partnerships at launch with an average session duration of 4 minutes 31 seconds.

Yes. We have hands-on experience with compliance-heavy products — including geo-adapted UX, data privacy patterns, and audit-ready interface systems. Regulated industries are part of our core expertise. This includes fintech dashboards with KYC/AML flows, responsible gambling tools in iGaming, and MedTech interfaces that must pass strict audits.

We work with both. Early-stage founders usually start with Product Concept or Post‑MVP Evolution, while established companies partner with us for full platform rebuilds, dedicated product teams and design system architecture.

A Fintech dashboard requires different logic than an iGaming platform. Regulatory constraints, data density, user trust signals, and interaction patterns differ completely. Generic design agencies learn your industry from scratch. We already know it.

Flatstudio has been trusted by 100+ clients across Fintech, SaaS, Sports Tech, iGaming, Govtech, and MedTech industries globally.

Yes. For Outlier we delivered a 20% conversion rate from free to paid users, reaching 1,000+ paid subscribers at $20/mo in six weeks with zero advertising. For RG we built a platform that secured 70+ media partnerships at launch with an average session duration of 4 minutes 31 seconds.

Yes. Our reviews are available on Clutch and other independent platforms where clients verify their experience directly.

Both. Our clients range from early-stage founders raising their first round to enterprise teams scaling complex platforms with millions of users.

Success is measured through hard numbers and qualitative feedback: paid conversion rates, MAU and sessions, average session time, deployment speed, partnership growth, design delivery reliability and user satisfaction. Each testimonial highlights specific outcomes — from 1M+ MAU and 3M+ sessions to 4x faster deployments and WCAG‑compliant interfaces for sensitive use cases.

Testimonials span a wide range of products: SaaS dashboards, sports prediction platforms, betting interfaces, media and research platforms, industrial and corporate sites, MedTech tools, AI‑driven apps and high‑security transport systems. Despite different industries, the common thread is complex, high‑stakes digital products where UX and design systems directly impact metrics.

Both. We work on public-facing projects as well as fully confidential ones under NDA. This is especially common in areas like FinTech, MedTech, Sports Tech, and GovTech, where privacy and security requirements are stricter. Even when a project cannot be shown publicly, we can often still share selected thinking, UX patterns, or anonymised learnings without revealing the client or sensitive details.

Many collaborations last for years rather than months. Scores24 and Stavka TV have worked with Flatstudio for 6–9+ years, continuously evolving sports prediction and betting platforms from early versions to high‑traffic products with millions of monthly users and sessions.

Clients typically see measurable improvements in conversion rates, session duration, activation and retention. For example, Outlier reached a 20% conversion rate from free to paid users and 1,000+ paid subscribers at $20/mo within six weeks, while RG secured 70+ media partnerships and 4+ minute session times in a research-heavy niche.

We specialize in high-complexity digital industries: SaaS, Fintech, Sports Tech, iGaming, MedTech, Govtech, Web3, News & Media, Travel, Commerce, and Corporate products. Each industry has unique logic, compliance requirements, and user behavior — we don't apply a generic approach. We focus on high‑load, regulated and data‑intensive digital products where generic design patterns usually fail.

In this industry, stagnation is death. We offer "Lifetime Evolution". We don't just fix bugs; we actively update your UX for new betting markets (Micro-betting), integrate new providers, and adapt flows for new regulations to ensure you always lead the market.

Not if done correctly. We practice "Safe UX Refactoring." We audit your current API structure and data constraints first. We redesign the visual layer (UI/CSS) and user flows to improve usability without requiring you to change your backend logic or database architecture. It’s a facelift for the engine you already have.

We specialize in "boring" high-load sectors. We don't guess—we start with a Logic Audit. We invest time to understand your terminology, user roles, and data dependencies before drawing a single pixel. We treat design as engineering: if it doesn't match the business process, it's not approved.

We speak your language. You get a Component-Based System (compatible with React/Angular/Vue). We deliver design tokens (colors, spacing, typography variables), Dev Mode specs in Figma, and interactive prototypes for complex animations. No "visual guessing"—your devs get a blueprint.

Yes. We reject the "Waterfall" agency model. We embed into your Jira/Linear process. We can deliver "Just-in-Time" design updates—preparing the UI for the next sprint while supporting devs on the current one. We become your dedicated design unit.

It's purely mathematical. Churn in SaaS often happens because users feel "stupid" or overwhelmed (High Cognitive Load). By simplifying onboarding, adding "Empty States," and clarifying navigation, we reduce the Time-to-Value. If a user gets value in 5 minutes instead of 50, they stay.

We prefer long-term partnerships. After the main release, most SaaS clients switch to our Dedicated Team (Retainer) model. We stay on board to design new features, run A/B tests, and maintain the Design System so your product doesn't degrade over time.

In this industry, stagnation is death. We offer "Lifetime Evolution". We don't just fix bugs; we actively update your UX for new betting markets (Micro-betting), integrate new providers, and adapt flows for new regulations to ensure you always lead the market.

Yes. We specialize in "Fintech-grade" interfaces. We know how to organize thousands of data points (odds movements) into clean, readable tables without overwhelming the user.

Yes. We have experience integrating lobbies from Evolution, Pragmatic Play, and others, ensuring a seamless flow between the platform and the game frame.

Absolutely. We use Generative AI to create consistent banners, landing pages, and social assets for your launch campaigns.

Yes, absolutely. We build the master structure in Figma, but we can export it as an editable Google Slides or PowerPoint file so you can tweak numbers and text before every meeting.

No, it is a high-fidelity simulation in Figma. It is fully interactive—you can click through flows just like a real app—but it does not run on code. It is designed to prove the concept and raise capital without burning budget on engineering.

Since we already designed the logic and prototype, we can transition straight into MVP development. This saves you 2–3 weeks of "onboarding" time because our engineering team already knows the product inside out.

Yes. You don't need wireframes or specs. We just need your vision, target audience, and raw data. Our "Week 1: Concept analysis" is specifically designed to turn vague ideas into structured product logic.

Yes. We act as a "Proxy Product Manager". We don't just execute tasks; we help you audit your backlog and decide which features will give the highest ROI for user retention and which technical debt needs fixing first.

We are "plug-and-play." We create a Slack, Jira, and Figma only for your project after sign of NDA and Agreement. We don't need a month of onboarding — usually, we ship the first design improvements within the first days.

That’s why we use a Scope-Based Retainer. We don’t lock you into a rigid 6-month plan. If you need to pivot from "new features" to "fixing retention" or “marketing assets” next week, we just adjust the backlog and keep moving.

In this specific "Post-MVP" plan, our core focus is Product Design & Strategy. However, we bridge the gap: we provide detailed specs, CSS tokens, and supervise your developers (Design QA) to ensure the code matches the design 100%. Need full-stack dev? Check our "Web App Engineering" solution.

We use phased, scope-based billing. Each phase (strategy, brand, UX/UI, engineering, launch) has a clear scope, estimate and deliverables. You always see what you are paying for per phase and can adjust priorities between phases as your business needs change.

No. We can focus on the most critical modules first — for example, onboarding, trading flows or admin dashboards — and modernise the rest in later phases. This staged approach reduces risk and lets you see ROI earlier while still moving toward a full relaunch.

Most redesigns focus only on “looking modern”. Our rebuild starts from product strategy, analytics and revenue mechanics. We keep the logic that works, remove features that don’t, and connect UX, brand and engineering to concrete metrics like activation, retention and ARPU — not just aesthetics.

We offer a "Chemistry Guarantee". If you feel the specialist isn't a match within the first week, we replace them immediately at no extra cost. No hard feelings, just business efficiency.

Yes. Our teams are structured to ensure at least 4-6 hours of overlap with EST/PST and CET time zones. We attend your daily stand-ups and respond to Slack messages in real-time during your morning.

No. We operate on a monthly retainer. You can scale up the team or cancel the engagement with a standard 14-day notice. We believe you should stay because of value, not a contract.

You do. From the moment of payment, 100% of the design source files and code belong to your company. We sign IP transfer agreements with all our specialists.

Most squads combine Product Designers, UI/UX Designers and Front-end Developers — with Design Leads or Tech Leads where needed. We can also include Product Managers, AI Designer or Design Ops profiles if your roadmap requires more strategy and coordination, not just execution.

The minimum engagement is 6 months. Anything shorter doesn’t give enough time to learn your product, ship meaningful work and measure impact. Most clients stay with us 12–24 months as we become an extension of their internal team.

We define success metrics together at the start — for example, features shipped per sprint, reduced design/dev backlog, improved activation or fewer support tickets. Every month you get a clear summary of shipped work, impact on key metrics and what we’ll focus on next.

We do both. Our team builds scalable Webflow sites and custom React/Vue.js applications with clean, modular architecture. That includes technical SEO basics, performance, secure backend integration and design hand‑off that engineers can implement without guessing. Many clients work with us for product design and keep us as their long‑term dev and Webflow partner.

Yes. We apply your visual identity to any physical medium. Whether it’s a restaurant menu, a fleet of cars, or office signage, we prepare print-ready files that guarantee perfect execution.

With our "Rapid Sprint" model, we can deliver a clickable core prototype and visual style in 2-3 weeks, ready for investor pitching or development.

Yes. We specialize in Refactoring. We audit your current logic, keep what works, and update the UI/UX layer to modern standards without disrupting your backend data structure.

Absolutely. We think like engineers. We use Figma Variables, Tokens, and Auto-layout. Your developers will receive a structured system, not just "pictures," speeding up implementation by 30-50%.

Not always. Often a "Brand Refresh" is enough. We can modernize your visual language to look current (Web3/AI ready) without losing the brand equity you've built over years.

It's a bridge between a moodboard and a mockup. It shows how your brand feels (textures, colors, typography) in one wide image. It ensures we align on the visual direction before spending time on the logo.

We ensure our designs are original. While we are not lawyers, we conduct availability checks and transfer all Intellectual Property (IP) rights to you.

Absolutely. From booth designs and roll-ups to premium swag and team apparel. We ensure your brand stands out on the expo floor and attracts investors.

Yes. We apply your visual identity to any physical medium. Whether it’s a restaurant menu, a fleet of cars, or office signage, we prepare print-ready files that guarantee perfect execution.

Yes, but we start with a quick audit. We need to check if your current assets are high-quality enough for production. If the foundation is solid, we can build cool stuff on top of it.

Yes. We provide a 30-day warranty period where we fix any bugs for free. After that, we offer flexible support retainers for adding new features, updating dependencies, and monitoring performance.

It depends on the "health" of your code. We start with a Technical Audit. If the architecture is solid, we refactor. If it’s "spaghetti code" that blocks scaling, we will recommend a rewrite to save you budget in the long run.

We partner with Push, a specialized engineering agency we've worked with for 8 years. Unlike "white-labeling" where agencies hide their vendors, we are transparent. Push engineers join our Slack, attend our sprints, and work directly with our designers. Flatstudio manages the product vision, Push ensures the code quality.

For small projects (Webflow, Framer, Wordpress), Flatstudio handles everything. For complex Web Apps (React/SaaS), you sign directly with Push for development to ensure zero markup on developer rates. We manage the process, but you pay the engineers directly. Transparency wins.

Not necessarily. Since we are a full-cycle partner, we can start development parallel to the design phase (using wireframes), which speeds up the time-to-market by 20–30%.

For clear, small-scope projects (like Webflow sites or MVPs), we work on a Fixed Price. For complex, evolving products (SaaS, Platforms), we work on Time & Materials (sprints), giving you the flexibility to change priorities without contract renegotiations.

Yes. We build on Webflow Enterprise. It offers bank-grade security and generates clean semantic code that Google loves. We optimize Core Web Vitals to green zones (90+).

Yes. We can act as your dedicated external design team for a fixed monthly fee. This is the best option for marketing teams that need a steady stream of assets (ads, social, decks) without administrative delays.

Absolutely. We build "unbreakable" master templates in Canva, PowerPoint, or Keynote. We set up font styles and layouts so your team can easily update text and images while keeping the brand look consistent.

Speed is key. For standard assets based on our design system (like banners or social posts), delivery is typically 24-48 hours. Complex assets like motion graphics or whitepapers take 3-5 business days.

We specialize in visual design and art direction. We need your copy and raw content, or we can use AI to generate it. However, we can structure the narrative for Pitch Decks and Landing Pages based on your inputs.

Absolutely. We think like engineers. We use Figma Variables, Tokens, and Auto-layout. Your developers will receive a structured system, not just "pictures," speeding up implementation by 30-50%.

Yes. We reject the "Waterfall" agency model. We embed into your Jira/Linear process. We can deliver "Just-in-Time" design updates—preparing the UI for the next sprint while supporting devs on the current one. We become your dedicated design unit.
