Existek vs ScienceSoft: pros and cons

Existek
+ 4.9 near-perfect Clutch rating with top-developer recognition in both Ukraine and Romania.
+ $25,000+ minimum project size is more accessible than large enterprise-only vendors like EPAM.
+ 12+ years of operating history (since 2012) with dual-country delivery presence.
+ Serves niche industries (oil & gas, business intelligence) less commonly covered by boutique AI specialists.
- Publicly available technical detail on Existek's specific AI/ML methodology is thinner than boutique specialists like Neurons Lab or Provectus.
- AI development is one of several service lines (custom software, staff augmentation) rather than the firm's exclusive focus.
ScienceSoft
+ 35+ years of operating history (since 1989) is among the longest track records of any firm in this list.
+ 4,200+ successful projects for 1,400+ clients provides an extensive delivery pattern library across industries.
+ 2018 Global IT Leader recognition from Clutch, part of the Clutch 1000, is an independently sourced distinction.
+ 750+ engineers and consultants with dedicated MLOps and generative AI consulting roles, not just generalist developers relabeled.
- AI is a comparatively newer addition to a company whose core 35-year identity is broader IT consulting.
- 750-person total headcount spans many practice areas, so AI-specific bench depth is smaller than the total suggests.
