Tensorway vs Cogniteq: 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.

Cogniteq

Cogniteq is a full-cycle software development company founded in 2005 and headquartered in Vilnius, Lithuania, with roughly 75–200 employees and additional offices in Poland and the US. It delivers custom technology services and products across industries, with agentic AI as a newer addition to its existing software development practice. As a Lithuanian and Polish EU entity, it sits fully within EU jurisdiction for its European delivery.

Tensorway vs Cogniteq: 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
Cogniteq
+ Fully EU-domiciled (Lithuania and Poland), simplifying GDPR compliance
+ Two decades of full-cycle software development history since 2005
+ Baltic-region cost base typically undercuts Western European vendors
+ Boutique headcount keeps senior engineers hands-on rather than delegated
- Agentic AI is a newer service line layered onto a generalist software development practice
- 51–200 team size limits capacity for large or highly parallel enterprise programs
- Reported headcount varies by source (roughly 77 to 200), worth confirming directly
