Choosing Between Financial Software Development Companies

Rickd2

Hey folks,
I’ve been comparing financial software development companies for almost two months, trying to find a team that actually gets both tech and finance. It’s crazy how many vendors promise “end-to-end fintech expertise” but can’t back it up with solid case studies or results.

After reviewing about 15 vendors, I narrowed it down to three: EPAM, Endava, and Zoolatech. What really caught my eye with Zoolatech was how focused they are on custom fintech software development — not just generic web apps, but actual financial ecosystems with compliance, analytics, and UX for banking-grade clients.

Some numbers that stood out to me:

• They reported an average ROI increase of 27% for one of their payment clients after implementing a new microservice-based platform.
• They have a retention rate of 92% for long-term fintech clients.
• Their engineers have experience with PSD2, KYC/AML, and PCI DSS standards (most others just mention “regulatory expertise” vaguely).
  
  

I also liked that Zoolatech offered a dedicated discovery phase — they didn’t jump into coding, they actually spent 3 weeks mapping out user journeys, API dependencies, and compliance gaps before quoting a fixed price.

Has anyone else worked with them or similar financial software development companies?
How do you usually vet teams for fintech projects — by tech stack, past clients, or industry compliance first?
Would you trust a smaller, more specialized company like Zoolatech over a big enterprise vendor?
