What do technology leaders say?
Hear from our partners
We’ve been working with The Software House for four years. They do such an excellent job at keeping projects on the track that I can now focus on the business areas of our products.
We regard the TSH team as co-founders in our business. In 12 months alone, we grew from 6 to 49 people, while our revenues and profits grew multiple times.

Frequently asked questions
What type of financial institutions and fintech software companies have you worked with?
For now, we can only mention projects with:
- A traditional bank that moved technology onto the AWS cloud with us. We used React, Serverless, and Node.js. Our design team later helped to rebrand their product’s UX/UI.
- A fintech with a B2B lending platform we supported with business logic work and development in React and Node.js plus Python.
- Another fintech called Energy Web (case study). They asked us to build a solar battery grid management app based on AWS, Ethereum, and Node.js.
- And yet another one called Arantio, where the founders flipped an intranet app into a payment processing platform for companies granting employee benefits
That experience plus 10 years of know-how can work for you.
We’re open to doing web development, business analysis, and cloud engineering work for traditional banks and fintech scale-ups. Representing a fintech software development company? Sure, let’s team up.
And if you need consulting services to failproof your strategy, guess what — your friend here can help too.
What services for the financial industry can you integrate?
We had success with connecting 8+ fintech-specific services that offer:
- EU, US, UK, and international payments in EUR with the set-up needed to earn the SEPA certificate
- International transfers in dozens of currencies
- 4 different payment gates that allow fintechs to accept debit plus credit cards, PayPal-like instant payments, and Google and Apple Wallet transfers
Simply put, expect your product to get packed with features all fintechs desire. Or as Microsoft would say it — “Introduce innovative business solutions today!”
How many developers from your software development company can I have in my team?
Let’s face it. You could use a technology partner that lifts you throughout years, and that’s why we’re ready to offer you a product team of 2 to dozens of experts.
One client that stayed with us for 6 years grew the team to 20 professionals.
You’ll also have the freedom to scale up or down depending on workload, and to delegate a project in full by adding one of our very convincing PMs to the group.
