All-in-one fintech software development

Kick-start your fintech project with a team that feels like yours

The Software House has 220+ developers, DevOps, QA’s, and designers rated ★4.8/5 also by executives at financial institutions. We build, advise, and question to deliver market-fit solutions.

Proven track record with the Fintech industry

Together, we’ll make your product competitive

The winning 36% of fintech companies become a force in the market thanks to a software partner (2020 Goodwin). Think of the billions in revenue behind Stripe or Klarna — the rising financial companies that bet on developing quality digital solutions that stay scalable.

In 9 years, we’ve built or upgraded over 160 products that needed a competitive edge. Now, our fintech software developers would like to help you succeed.

A team that understands your field

The financial industry challenges we deal with

The Software House’s talent has been architecting, creating, and maintaining systems for companies at Seed A, B or C, and those expanding into new markets. We understand the business and technology problems fintechs face on the road to millions of users.

The answer:

Don’t have a clear development plan?

You will

Best way to deal with a problem? Ask the people who’ve been through it a lot of times.

You have a vision and we have ways of removing roadblocks you might not see. 9 years of work for 24 countries taught us to build products based on three rock-solid principles: flexibility for developers; scalability for years; usability for millions. The best practices we established will help your team move forward.

Using pre-built cloud components with our original programming, we’ve created CMSes, a lending platform, employee management systems, a streaming service, and other projects for bank and financial organizations. You’ll always know what’s the best decision to make.

The answer:

Want to use the cloud effectively?

Consult certified AWS engineers

Multiple surveys of the IT industry in the past years have kept cloud adoption among the top 5 challenges for executives. There’s too much at stake to do big-scale cloud work without guidance.

Connect your team with our group of 36 cloud engineers who led dozens of migrations to exchange practical knowledge and develop resilient cloud-native solutions.

You will see that the future application is budget-optimized, has unshaken service accessibility, and can be scaled without failures from country to country.

The answer:

Data privacy and security matter?

Expect no backdoors

Fintechs follow some of the strictest government regulations. We already work under them with a U.S. health tech company and a Dutch bank to secure systems and users with full GDPR compliance.

Our team will adapt to your company’s policy because we offer what’s usually required: security-certified technology; centralized authorization and identity management; “at rest” and “in-transit” data encryption.

To share responsibility for the project’s cybersecurity is always a part of the deal for us.

The answer:

Unsure how many people you need?

Scale the team on the go

Developing financial services is unpredictable. Why not start with a one-pizza team?

Our clients appreciate the option of adding another financial software developer on the go. And if you need advice on how to handle financial software development, ask our CTO, Architects, or DevOps for a consultation or an R&D project.

Even for 1-year projects, the number of developers our clients need often goes from 4 to 20.

The answer:

Need a culture fit?

We have high standards just like you

60% of The Software Houses’ projects come from referrals because there are no second-hand clients here.

You have your way of doing things, which we’ll always recognize and respect. Building products across 20+ industries taught us to represent responsibility in management, fairness in cooperation, and initiative in action.

Who says so? The executives who ranked The Software House as 2020’s Top Software Development Company in Poland. Could be the only fintech software development company you’ll need.

Years in cloud engineering

C-level security practices

Choose to work with an organization that knows security starts with people. Each contract we offer is in compliance with GDPR and NDAs.

We can collaborate in VPN environments, develop on bastion host architecture, or participate in and offer client-issued security tests. The tools we have in our tech radar must come with security certification.

Rapid-development and integrations

Upgrade the product faster with pre-made services that save months of development.

Among them: banking and lending platforms; international payment gateways; and reporting services. Your new durable team will connect them with the tools your company uses like Salesforce or Twilio.

Growth-oriented development

Fintech case studies

The market’s pace of change is challenging. The Board has unbending expectations. And then you have your users who can switch their platform if there are too many bumps.

You need a forward-thinking partner who knows how to develop at a scale from a national to a multi-country level. These companies needed that too — see how much they achieved.
