Tensorway vs BotsCrew: overview

Tensorway

Tensorway is the AI-focused unit of an established software development company headquartered in Alicante, Spain, with roughly 25 years in the market, giving it an EU legal entity and EU data residency by default rather than as a retrofitted option. Its six-phase delivery methodology names compliance — GDPR, HIPAA, and ISO 27001 — as an explicit phase rather than an afterthought, and its lightweight, API-first architecture is designed to connect into a client's existing systems without a platform overhaul. As a Spanish company operating fully within EU jurisdiction, it avoids the cross-border data-transfer questions that non-EU vendors on this list have to answer.

BotsCrew

BotsCrew is a conversational AI development company founded in 2016, with reported headquarters in London, UK (also San Francisco) and delivery teams in Lviv, Ukraine and Adelaide, Australia, totaling roughly 73 employees. Led by CEO Nazar Hembara and Managing Director Max Gladysh, it has extended its original chatbot-development practice into autonomous, multi-step agentic systems. Its London office gives it a UK legal entity for European clients, while its Lviv delivery team sits outside the EU proper.

Tensorway vs BotsCrew: pros and cons

Tensorway
+ Fully EU-domiciled legal entity avoids cross-border data-transfer complexity for European clients
+ Compliance embedded as a named phase in the delivery methodology, not an add-on policy
+ Lightweight, API-first architecture connects into existing systems without a platform overhaul
+ Six-phase methodology reaches a working MVP in roughly a month
+ Backed by a parent company with two-plus decades of European software delivery history
- Team size (50–249, shared across the parent company's broader practice) is smaller than several global systems integrators on this list
- Published case studies are a short list, so depth outside those verticals is less proven
- Minimum engagement and project-count figures are sourced from the company's own site and independently unverifiable
BotsCrew
+ London office gives it a UK legal entity accessible to European clients
+ A decade of dedicated conversational AI development history since 2016
+ Founder-led (Nazar Hembara, Max Gladysh) continuity
+ Dialogue-design expertise transfers directly into more natural agentic conversation quality
- UK-headquartered, so post-Brexit it sits outside strict EU jurisdiction for its own corporate entity
- Lviv, Ukraine delivery team sits outside the EU proper — worth confirming per-project data handling
- ~73-person team caps capacity for large or highly parallel enterprise programs
