Nexocode vs STX Next: pros and cons

Nexocode
+ Small, senior team (~25 people) means direct access to experienced engineers rather than junior staff augmentation
+ AI Design Sprint offering gives clients a structured, low-risk way to scope a project before committing
+ Kraków HQ taps into Poland's deep software engineering talent pool
+ Flat structure can mean faster internal decision-making on scoped projects
- ~25-person team size limits capacity for large, multi-workstream enterprise programs
- Founding year has conflicting public sources (2015 vs. 2017) — 2015 is used here based on customer testimonial evidence
- Named clients (Katana, Leavetown.com) are smaller-profile than several competitors' enterprise logos
STX Next
+ Largest Python-focused software company in Europe (per company website), giving deep bench strength for Python-native ML engineering
+ Certified across AWS Advanced Tier, Snowflake, Databricks, Azure, and Amazon Bedrock simultaneously — an unusually broad multi-cloud partner portfolio
+ Open-sourced its own autonomous AI dev agent (DeepNext), demonstrating in-house AI R&D beyond client work
+ 330 employees and a fully remote model across the US, UK, DACH, and Poland gives wide delivery flexibility
- AI and ML is one part of a much broader Python software-development practice, not the company's sole specialization
- 330-person scale means less boutique-style founder involvement than smaller specialists on this list
- Broad industry spread from banking to oil & gas trades vertical depth for breadth
