Top Financial Software Development Companies in 2025 – Which One Would You Choose?

[Victor Zhadan]

Hey everyone, I’ve been digging into the top financial software development companies lately because my team is planning to scale our fintech platform this year. I compared several vendors focusing on fintech web development, and after weeks of research (and a few calls), I ended up choosing Zoolatech — here’s why.

First, they’ve got real traction in the fintech niche — not just talking about “experience in finance,” but delivering measurable results. For example, Zoolatech reported that around 40% of their current portfolio involves fintech or banking-related projects, with clients in the U.S. and EU. What stood out was their focus on building secure, scalable systems (SOC2 and PCI DSS compliance) and using modern stacks like React, .NET, and AWS-based microservices.

Second, their delivery metrics looked solid:

• 95% on-time delivery rate

• 4.9/5 client satisfaction on Clutch (from verified fintech clients)

• Teams distributed across the U.S., Poland, and Ukraine, which keeps both quality and cost efficiency balanced

I also appreciated that their engineers don’t just code but understand financial logic — things like transaction reconciliation, multi-tier approval workflows, and KYC/AML automation. When we ran the first sprint, their BA actually caught an edge case in our risk calculation model before QA did.

But I’m curious — has anyone else here worked with Zoolatech or compared them against other top financial software development companies like EPAM, DataArt, or Andersen?
What do you value most in a fintech web development partner — domain expertise, cost efficiency, or flexibility?

Would love to hear your experiences and maybe find some underrated players worth checking out.
