Client Testimonials
REVIEWS
We wanted to enhance our shipping solutions by migrating our desktop-based platform and its users to a new web application. Good KPIs met our expectations, generating plans for future collaboration with Eastern Peak.
interview on Clutch
We had a development challenge, as well as a business one. We needed quality people quickly, so we decided to approach Eastern Peak. The results were excellent and we were able to exploit the full potential of the IoT.
interview on Clutch
Eastern Peak assumed responsibility for their results and never tried to deflect it. They stood behind their promises and were very pragmatic. We have received input on app development as well as on our general business model, which helped a lot.
interview on Clutch
We needed to find people who were experienced specifically with startup schedules. Most of the people I’ve worked with had experience of five or six startups, and they’re in their mid-20s. These guys have a good reputation, and I just got very lucky to work with them.
interview on Clutch
They gave me the knowledge, expertise, and experience I needed to launch everything from the beginning and to support it further. They’re like a partner in terms of thinking and creating new concepts, new features, and new ideas.

FAQs on Personal Finance Software Development
1. What types of personal finance apps do you build?
We build budgeting and PFM apps, savings and goal-based tools, investing and robo-advisory features, and debt and credit management, either as a single product or as part of a wider money-management platform.
2. How do you build a personal finance app?
Every app is different, so we begin with a discovery phase to define the scope, users, and compliance needs, then agree a roadmap. From there we build iteratively, releasing a working version early and expanding it in stages, with security and regulation handled throughout. You stay involved and sign off at each milestone.
3. How do you handle security and data privacy?
Security and privacy are designed in from the start: encryption, MFA, audit logging, and adherence to PCI DSS, PSD2, GDPR, and KYC/AML requirements relevant to your market. We never sell user data.
4. How long does it take to build a personal finance app?
It depends on the scope. A lean first version reaches release faster than a full-featured product. We define the scope, timeline, and budget together during discovery, before any code is written.
5. Do we own the code and IP?
Yes. You get full ownership of the source code and IP, with complete repository access, no vendor lock-in, and no mandatory monthly platform fee.
