Flatstudio has been trusted by 100+ clients across Fintech, SaaS, Sports Tech, iGaming, Govtech, and MedTech industries globally.
Can you share real results from your projects?
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.
Do clients leave reviews on third-party platforms?
Yes. Our reviews are available on Clutch and other independent platforms where clients verify their experience directly.
What do clients value most about working with Flatstudio?
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.
Do you work with startups or only established companies?
Both. Our clients range from early-stage founders raising their first round to enterprise teams scaling complex platforms with millions of users.
How do you measure success in your projects?
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.
What types of products do these testimonials cover?
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.
Do you only work with public case studies, or also under NDA?
Both. Some projects, especially in FinTech, MedTech, Sports Tech and GovTech, remain fully confidential due to strict NDAs and security requirements. In those cases we anonymize brands but still share architectural frameworks, UX patterns and outcomes such as deployment speed, data‑heavy UI performance or compliance results.
How long do your client partnerships last on average?
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.
What kind of results do your clients usually see?
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.
