MobiDev vs Existek: pros and cons
| MobiDev | |
|---|---|
| + | Clutch's #1 Machine Learning development company ranking in 2021 is a third-party, verifiable recognition rather than self-reported. |
| + | Dedicated AI consulting/engineering practice since 2018, not a general software shop retrofitting AI onto its offering. |
| + | Dual R&D centers in Poland and Ukraine provide geographic delivery redundancy. |
| + | 15+ years of company history (since 2009) predates the current AI hiring boom, indicating organic rather than opportunistic AI growth. |
| - | Employee-count sources conflict meaningfully (150 on Clutch vs. 400+ on company materials) — confirm current AI-team headcount directly before contracting. |
| - | US headquarters is primarily a commercial front office; delivery is centered in Poland/Ukraine, which is standard for the model but worth knowing upfront. |
| 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. |
