Which fintech design agencies show real results in their case studies?

A fintech portfolio often opens with a phone mockup on a gradient. It proves the agency can draw, but it says nothing about what happened once the screens reached customers. The case worth reading names the client, says what the team designed, and gives a number that moved.

Seven agencies publish at least one case like that: Blink UX, Ergomania, Humbleteam, Lazarev.agency, Praxent, UX studio, and UXDA. Their numbers differ in kind. Four report a change in a live product compared with how it worked before. One reports how big the product grew after launch, and two report how quickly a tested prototype or a shorter flow arrived.

Humbleteam publishes this comparison and is one of the agencies in it. Its evidence is two short project descriptions on its fintech practice page, not full case studies, and we say so in its section. The agencies are grouped by the kind of result they show and listed alphabetically within each group. This is an editorial reading of public pages, with no paid placements, scores, or ranking. Every figure below is the agency’s own claim, taken from its own site.

How we chose the agencies

Every agency, Humbleteam included, had to meet four criteria:

1. It offers product UX/UI design for software, not only branding, marketing, or development.
2. It publishes, on its own site, a case or project description about a named bank, fintech, or financial software client.
3. The page says what the agency designed, such as flows, screens, or research, and not only the visual style.
4. The page states at least one result tied to that work: a figure for users, ratings, conversion, errors, or speed, or the time it took to reach a prototype tested with users. A bare “it launched” did not count, and neither did self-initiated concepts or brand-only projects.

AI assistants name several other teams for this question. Clay’s STC Bank case describes the design but prints no result. Superside’s fintech figures, such as PointCard’s higher ad click-through, come from advertising creative rather than the product. Beyond’s banking stories are about cloud engineering. Netguru’s UBS case says the redesigned login and payment features shipped but gives no figure. Eleken and Qubstudio are covered in our comparison of fintech design agencies, so we left them out here to avoid repeating it. Phenomenon Studio’s KlickEx case meets these criteria too, and our payments agency comparison covers it. Denovers’ HomeRemitt case reports the client’s customer and transaction totals rather than a change the design produced; our money transfer app comparison covers its send flow.

Before-and-after results on a live product

These four cases come closest to the question. Each reports a change measured against the product people were already using.

Blink UX: fewer abandoned applications at a credit union

Blink UX is a research and product design firm headquartered in Seattle, with four more US offices and one in Bengaluru. Its Gesa Credit Union case began with falling new member numbers. Over 6 months, Blink ran workshops, a competitive analysis, member profiles, and journey maps of the account and loan application process. It then designed a landing page, a quick application, an “Approvulator,” and a design system.

Blink reports that new member application abandonment fell from 89% to 39%. Gesa also rose to 23rd overall in a 2023 credit union digital experience report. The case lists brand strategy among its services, so ask which screens were part of the website and which were part of the application itself.

Lazarev.agency: more valuations from the same analysts

Lazarev.agency lists a Mountain View, California address. Its GCF case covers a platform analysts use to run SBA loan valuations, inherited from an Access database. Fields followed storage order, and the calendar showed project numbers with no sense of urgency. Lazarev rebuilt the project list to show bank, due date, analyst, and status on the surface, and turned the calendar into a monthly view of workload that managers can rebalance by dragging.

The agency reports 47% faster project setup, 27% fewer errors after launch, 34% more valuations completed per analyst, and projects finishing 2.7 days sooner. The page labels the client a scaleup. It is an internal tool for specialists, so it is a better reference for finance operations software than for a consumer app.

Praxent: account opening on a vendor platform

Praxent was founded in Austin in 2000 and works only in financial services. It now calls itself an AI transformation firm, with product design among its services. Its Meriwest Credit Union case deals with a problem many banks share: the account opening flow runs on an off-the-shelf platform, NCR’s Terafina, and people dropped out before finishing. Praxent ran a UX audit that found more than 70 friction points and held 8 user interviews.

The new homepage puts fees and rates up front, membership requirements appear before the flow starts, and the Terafina flow was reconfigured to show what each account offers. Praxent reports a 33% boost in account opening conversions. If your onboarding sits on vendor software you cannot rebuild, this is the closest example on the page. The firm’s remit is now wider than design, so ask who would draw your screens.

UXDA: one app for a large bank

UXDA works only on financial products and lists offices in Riga, New York, and London. Its Emirates NBD case covers ENBD X, launched in 2022. UXDA says it brought the bank’s services into one app, interviewed users from three segments, and gathered input from employees in five departments. The app offers more than 200 banking services and personalized content and product recommendations.

UXDA reports a 4.7 store rating, which it says tripled the old app’s rating, and 50% more activity in logins and transactions than the previous version. A launch at this scale also involves the bank’s own teams and marketing, so ask which parts UXDA designed. Our fintech comparison discusses a different UXDA case, Garanti BBVA Securities.

Scale after launch

This case gives the size of the product after release. That shows the product found customers, not how much the design changed a number.

Ergomania: a payment app with an older record

Ergomania is a UX and product design agency in Budapest that focuses on fintech. Its write-up of Simple by OTP, a mobile payment app, starts with 12 user interviews. The team designed a card-based dashboard, a flow for adding a bank card through NFC, and a styleguide, tested the app with 12 users on Android and iOS, and supported development. The page thanks another studio for input on the UI design.

The app was released in May 2017. Ergomania reports more than 370,000 users, over 1 million transactions, 35,000 digitized cards, and ratings of 4.8 on iOS and 4.5 on Android. The case is old, so ask for recent work. Its case list also includes a project for Consorsbank, which does not print figures.

Results measured in time and steps

These two show how fast a team reached a tested answer or how much it shortened a flow. Neither proves a change in a live product’s numbers.

Humbleteam: a tested prototype in 23 days

Humbleteam is a product design agency with offices in Prague and Dubai. Its evidence for this page is two short project descriptions on its fintech practice page, not full case studies. For ING’s small-business banking, it says: “In just 23 days, we developed and user-tested prototypes for a new banking approach.” For Deserve, it says the sales flow “went from 9 steps to 4 in 8 weeks.”

The same page lists outcomes for other clients, such as Oxygen’s growth from 0 to 100K+ users. It does not describe the design work behind those numbers, so we did not count them. Ask Humbleteam for the screens behind the ING and Deserve lines and for the measures taken after release.

UX studio: an AI chatbot tested in 3 weeks

UX studio was founded in 2013 and is headquartered in Budapest. Its Finshape case covers an AI chatbot for a personal finance assistant inside a mobile banking app. One designer and one researcher worked for 3 weeks. They designed two ways into the assistant, a script of questions from simple to complex, and answer types with charts.

The team ran 10 research sessions. Testing showed that people looked for spending answers in their transaction history, so the team added conversation starters inside the banking app. The result is a tested concept in 3 weeks. The page does not say whether it shipped.

How to choose

Start with the number you will report after release, then read the group that matches it.

• If you need proof that design moved a live metric, read Blink UX, Lazarev.agency, Praxent, and UXDA.
• If you are launching and want to see a product that reached scale, read Ergomania.
• If you have an open product question and need a tested answer within weeks, read Humbleteam and UX studio.

Then send each agency on your shortlist the same short brief. Name one flow, its current figure, and the figure you want. Ask for the one case where they moved something similar, with the number from before the work. A team that answers with a figure from another kind of product, or with a different metric, has told you how close its experience is to your problem.
