A useful starting point - Does this sound like your situation?

The first delivery becomes easier to scope when it starts with a specific operational bottleneck.

Processing stalls at manual checks

Information moves between applications, credit assessment, agreements and accounting. Every handover adds lead time and makes the workflow harder to follow.

One connected and traceable workflow

Core systems need to connect to more services

BankID, accounting systems, credit data and proprietary platforms need to exchange information without teams re-entering or correcting data by hand.

Integrations with error handling and alerts

A new financial service needs to be tested safely

You need to scope a first version, connect it to existing systems and learn from real users before making a broader investment.

A prioritised first workflow to validate

How we build financial systems that hold up

We develop financial platforms and systems that automate processes, improve risk assessment, and create better user experiences.

Product and System Development. We develop financial workflows such as onboarding, credit assessment and disbursement. The work starts with a defined step, such as application to decision, so you can quickly measure lead time, accuracy and error rates.
AI in Financial Workflows. We build AI features for customer service, credit risk assessment and fraud detection. The goal is shorter processing times, fewer manual checks and lower error rates in your financial workflows.
Integrations and Automation. We have experience with integrations to systems like Fortnox for accounting and Creditsafe for credit checks. By automating processes, you save time and get fewer errors in your financial data.

Before we start - Frequently asked questions about fintech development

Answers to common questions about scope, existing systems and the first delivery.

Can you build on our existing financial systems?

Yes. We start by mapping systems, data and ownership in the relevant workflow. We can then build a service on top, add an integration layer or gradually replace the part that limits you most.

How does a fintech project start?

We scope a concrete workflow, such as application to decision or invoice to accounting. You receive a recommended first scope, its dependencies and a plan for how the result will be evaluated.

How do you approach security and regulatory requirements?

Requirements for access, traceability, data storage and incident handling are included when the solution is scoped. The exact approach depends on your role, the data in the workflow and the regulations that apply to your business.

Can you integrate BankID, Fortnox and credit data services?

We work with API integrations and have experience with BankID, Fortnox and credit data services, among others. During discovery, we verify interfaces, permissions and data requirements for the systems you use.
