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.

+ Multi-continent office footprint (US, Europe, South America, India) supports global delivery.
+ Twelve-plus years of continuous operation as a bootstrapped, profitable company (per reporting on ~$100M ARR).
- Employee headcount estimates vary meaningfully by source (roughly 600–950), creating some uncertainty.
