Persistent Systems vs N-iX: overview

Persistent Systems

Persistent Systems was founded in 1990 and is headquartered in Pune, India, with roughly 23,900 employees, a fraction of the size of Infosys or TCS, but with a more concentrated focus on software product engineering rather than broad-spectrum IT services. It works extensively with independent software vendors and technology companies building the actual product a US buyer sells, work that sits closer to the product itself than the back-office IT operations most of its peers focus on. That focus makes it a more natural fit for a software company specifically, compared to the sprawling generalist practice of a much larger Indian peer.

N-iX

N-iX was founded in Lviv, Ukraine in 2002 and has since opened offices across eight countries, including the United Kingdom, growing to more than 2,000 employees. That geographic spread is a deliberate answer to a real concern a US buyer might raise about single-country delivery risk in the region, N-iX can shift capacity across its multi-country footprint rather than depending entirely on Ukraine alone. It doesn't carry a US legal entity, so contracting still routes through Europe, but the multi-country model offers more delivery-continuity assurance than a single-office competitor.

Persistent Systems vs N-iX: pros and cons

Persistent Systems
+ Focused specifically on software product engineering, a better fit for an actual tech company than a generalist IT-services vendor.
+ Meaningfully smaller than TCS or Infosys, so it can offer closer account attention at real enterprise scale.
+ Strong track record partnering with independent software vendors specifically, a different client base than the enterprise back-office accounts most peers chase.
+ Publicly traded with financial disclosure, giving procurement a verifiable track record.
- Smaller total capacity than the largest Indian majors, so it's a weaker fit for an extremely large, multi-thousand-person program
- Most delivery remains India-based, with limited domestic US presence compared to a firm like Infosys or Cognizant
N-iX
+ Eight-country office footprint gives it real delivery-continuity options that a single-location competitor can't offer.
+ UK office adds a European legal presence beyond its Ukraine origin.
+ Established, 20-plus-year track record with mid-size and large enterprise clients.
+ Broad technical range across fintech, healthcare, and supply chain delivery.
- No US legal entity, so contracting and invoicing still route through a European jurisdiction
- At roughly 2,000 people, it can't match the raw staffing scale of the largest generalist firms on this list
