Neurons Lab vs Existek: pros and cons
| Neurons Lab | |
|---|---|
| + | Founders are practicing ML engineers (CTO is a published deep learning author), so scoping conversations are technically grounded. |
| + | Small team size means senior staff stay on the engagement instead of rotating off after the pitch. |
| + | Track record spans over 100 AI implementations across regulated and non-regulated sectors since 2019. |
| + | Advisory-first model reduces the risk of over-building before validating an AI use case. |
| - | 51–200 headcount caps how many concurrent enterprise engagements the firm can run. |
| - | No public case study library with quantified before/after metrics — most proof points are narrative. |
| - | Not a fit for teams that need large-scale staff augmentation rather than a scoped advisory engagement. |
| 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. |
