What to Look For in Fintech App Development Companies 

Choosing the right FinTech app development company to build your FinTech app or solution is a crucial decision that could affect the success of your project. Therefore, when considering your options, it is advisable to assess them based on the following criteria. 

We selected the top Fintech software development companies on this list based on these same decision-making factors. They include: 

1. Client-centric collaboration 

The best Fintech app development companies ensure that they keep their clients front and center throughout the project lifecycle. Their software development efforts are always focused on the client’s needs, feedback, and business goals. Basically, look for a FinTech software development company that’s professional and focused on building your FinTech app according to your specifications. 

But, how do you know a client-centric FinTech app development company? 

You can always recognize one through their past customer reviews. Look out for the genuine connections and try to discern if indeed their past clients felt understood in the development phase. 

2. Tech expertise 

The company’s tech expertise is its core ability to actually build the kind of FinTech app you want to develop. This means you have to assess the company’s expertise in major technologies (like big data, artificial intelligence (AI), mobile, and web development), programming languages, frameworks, and tools essential for building the best financial applications. 

This is perhaps the most important thing to look out for because your FinTech app will be holding sensitive customer information. Therefore, you need a company that can create an app capable of delivering flawless performance under strict regulatory scrutiny. 

3. Relevant portfolio

You should also check out how many finance app projects a FinTech app development company has built before choosing them. Taking a close and hard look at their case studies helps you measure the company’s experience in building apps similar in scope, complexity, and regulatory requirements to your intended project. And of course, seeing similar successful projects reduces the risks of project failure or misalignment with regulatory and security standards. 

4. Business development expertise 

Business-oriented decision-making is also a key attribute possessed by top FinTech development companies. This implies that the partner values business success over simply delivering features. 

So, how can you identify FinTech development companies with enough business development expertise? 

Firstly, they often have a business analyst on their dedicated development team. Such professionals allow them to provide better business solutions. Sometimes, this may even mean that they will challenge your vision and refine it to better align with your overarching business goals. 

5. Time to impact

A FinTech app development company’s time-to-impact is how long it takes to influence your product vision after the initial contact. You want to avoid a company that drowns you in excess paperwork and formalities because building an impactful solution can be very time sensitive due to the dynamic nature of the FinTech industry. 

On the other hand, development companies with a streamlined onboarding and development approach tend to impact your product more quickly. So, when making your decision, examine how the company manages its resources, the number of tech advisors and tech leaders on the dedicated development team, and, most importantly, how agile its approach is. 

6. DevOps culture 

A company’s DevOps culture describes its approach to close collaboration and shared responsibility between development and operations for the products it creates and maintains. This is a vital decision-making factor because FinTech app development can be very dynamic. User needs evolve, and business goals change accordingly with market demands. Therefore, it is very important to partner with a dedicated development team capable of cooperating closely with your internal teams without knowledge hubs. 

It is essential to collaborate with a company that follows the DevOps culture and is willing to share information transparently.

Conclusion

Finding the right fintech software development company can be a game changer for your fintech startup or enterprise. It puts your technological development responsibilities in the hands of an experienced and dedicated team who knows what it takes to thrive in finance. More importantly, it gives your brand a competitive edge. 

If you’re constantly caught between business development and building a strong tech product, it may be time to trust a capable company with those product development responsibilities.
