The company
PayVault operates in the fintech space, where expectations are high and the margin for error is small.
PayVault is a digital wallet startup that needed a secure, fast, and friendly way for users to store money, pay merchants, and send transfers. They came to us with a prototype and a tight regulatory bar to clear.
The problem they faced
Payments demand trust. PayVault needed bank-grade security and fraud protection without making the everyday experience slow or clunky.
Left unsolved, this capped growth and added friction for the team and their customers alike - which is what prompted them to look for a partner who could fix it properly.
Why they came to Ecomsy
After comparing several agencies, PayVault chose Ecomsy for our senior, end-to-end team - one group handling strategy, design, development, and QA - and our track record of shipping fintech products that actually perform in production.
The challenges we had to solve
- Meeting ambitious goals in fintech without blowing the budget or the timeline.
- Building something secure, reliable, and ready for real-world load from day one.
- Keeping the experience simple for end users while handling real complexity underneath.
- Making sure the PayVault team could own, run, and extend the product after launch.
The options we weighed
We mapped a few possible directions together: an off-the-shelf platform, a lightly customised template, or a purpose-built solution. Off-the-shelf was fast but too rigid for what PayVault needed; a template would have saved time upfront but cost far more later. We weighed cost, speed, control, and long-term flexibility side by side.
What we chose - and why
We chose a purpose-built approach on a modern Swift stack - the option that best balanced time-to-market with the control and scalability PayVault needed. It let us tailor every part of the experience while keeping the codebase clean and easy to extend.
Our approach
Discovery
We mapped PayVault's goals, users, and constraints to shape a focused, realistic plan, and agreed on what success would look like.
Design & prototyping
We designed the flows and interface, then validated the direction early with clickable prototypes before a line of production code was written.
Development
Our team built PayVault in milestones with clean, scalable, well-tested Swift code - so progress was visible the whole way through.
Launch & support
We shipped, monitored performance closely, and stayed on to refine, fix, and add features after go-live.
How we solved it
Working in milestones, we built and shipped the core of the product, then layered in the details:
- Native iOS and Android apps with biometric authentication
- A hardened backend with tokenised transactions and encryption at rest
- Real-time fraud checks and anomaly detection
- Instant peer-to-peer transfers and merchant QR payments
- A compliance-ready audit trail for every action
The results
“Ecomsy shipped a secure, fast wallet our users genuinely trust.” - CTO, PayVault
The impact
Today, PayVault delivers measurable results - 250k+ transactions/mo and counting - with a solid technical foundation and a partner to keep improving it. The problem that once held them back is now a strength they can build on.
