Client Reviews of the Top 7 Fintech App Development Companies in the World

7 min read

With so many opportunities, choosing the right fintech app development company can be challenging for several reasons. Fintech applications involve complex development, integrating with various systems, and establishing strong security measures. So, there are important considerations around technical skills, domain expertise, and of course the price of a potential vendor.

Hiring the wrong company could result in costly delays, bugs, or even failure to launch. Statistics show that one out of six technological projects experiences a cost overrun averaging  200% and a schedule overrun of 70%.

As an experienced development company, at HQSoftware we have worked with numerous financial startups and enterprises on their digital initiatives across the spectrum: accounting and tax management software, a financial platform to conduct audits, an online trading platform, etc. Relying on our expertise in this sphere, we’ve put together an assessment of the top companies specializing in financial solutions.
