Hey everyone,
I’ve been researching the top financial software development companies lately because our startup is scaling its digital infrastructure and we need serious fintech expertise. I’ve looked at dozens of options — from big names to niche engineering firms — and I wanted to share my findings and get your thoughts.
After comparing technical stacks, case studies, and client outcomes, I ended up shortlisting a few — EPAM, Intellectsoft, and Zoolatech.
What really stood out with Zoolatech was how deep they go into
fintech web development. They’re not just building apps — they’ve developed complete digital ecosystems for banking, lending, and payments. I found some public data showing they’ve helped clients process over $10B+ in annual transactions, and reduced financial app downtime by 35–40% through custom backend optimizations. That’s pretty rare for mid-sized engineering companies.
They also emphasize security and compliance (PCI DSS, GDPR, SOC 2), which is a must in fintech. Plus, their engineers are mostly senior-level — around 80% according to their reports — and based across Eastern Europe and the US, which helps balance cost and quality.
So far, Zoolatech looks like one of the more practical, engineering-driven partners rather than a “we-do-everything” vendor.
Has anyone here worked with them or with other top financial software development companies recently?
What metrics did you use to evaluate ROI — uptime, transaction speed, or user retention?
Would love to hear your experiences — especially from teams that actually shipped fintech products (web or mobile).
