Persistent Systems vs ScienceSoft: 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.
ScienceSoft
ScienceSoft was founded in 1989 and is headquartered in McKinney, Texas, with more than 750 technical professionals on staff. Its client list includes IBM, Ford, eBay, Walmart, and NASA, and it holds a 4.8 rating on Clutch along with recognition in the IAOP Global Outsourcing 100 list across multiple years. Its Texas base and nearly four-decade operating history predate the wave of Eastern European IT-outsourcing firms that opened around and after 2000, giving it one of the longer track records on this list.

Persistent Systems vs ScienceSoft: 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 |
| ScienceSoft | |
|---|---|
| + | A US headquarters in Texas that dates to the company's founding, unlike a sales address added years afterward. |
| + | Nearly four decades of operating history, longer than most competitors on this list. |
| + | Named clients including IBM, Ford, and Walmart back its enterprise credibility. |
| + | Strong third-party review ratings, a 4.8 on Clutch, and repeated IAOP Global Outsourcing 100 recognition. |
| - | At roughly 750 professionals, its total capacity is smaller than most of the mid-size firms on this list |
| - | Marketing materials lean heavily on named client logos, worth verifying the specific scope of each relationship directly rather than assuming full-program ownership |
