Cross-border payment infrastructure for eCommerce and fintech

Financial Services London, UK 201–500 employees Founded 2009 Privately Held

Unlimit operates a multi-service payment platform spanning gateways, card acquiring, business accounts, and crypto on/off-ramps across 25+ countries. The tech stack reveals infrastructure maturity (Kubernetes, Terraform, Oracle, PostgreSQL + pgvector) paired with emerging AI tooling (LangChain, LangGraph, RAG), and active projects show a shift toward AI-enabled monitoring and real-time data integration — suggesting a move from traditional payment pipes toward intelligent risk and compliance automation. Sales hiring outpaces engineering 3:1, typical of a founder-led payment operator scaling go-to-market while consolidating backend.
