Neurons Lab vs Sigmoid: pros and cons
| Neurons Lab | |
|---|---|
| + | Engineering-first positioning, differentiating from pure strategy consultancies. |
| + | Stated Fortune 500 client experience and 100+ completed implementations since 2019. |
| + | Distributed European team offers timezone flexibility for EU and UK clients. |
| + | Focused financial-services vertical depth rather than spreading thin across many industries. |
| - | No single headquarters makes on-site/in-person engagement models harder to arrange. |
| - | Named client list and case study depth are not independently verifiable beyond company claims. |
| - | Team size (50+) caps capacity for very large concurrent enterprise programs. |
