Gradient Labs vs Cogniteq: pros and cons

Gradient Labs
+ Founding team's direct experience at Monzo (a regulated UK bank) feeds real compliance fluency into Otto
+ Named, benchmarked production agent with disclosed resolution-rate and QA-pass-rate figures
+ Venture-backed ($13M+ Series A) with runway to keep investing in the product
+ UK domicile with a narrow, deep focus on regulated financial services specifically
- Very narrow focus (financial-services customer operations) — not a fit for other verticals or broader custom agent builds
- Small team (~46 employees) limits capacity and account-management bandwidth
- As a product company rather than a services firm, engagement is closer to platform licensing than bespoke development
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
