Gradient Labs gives every bank customer an AI account manager

Gradient Labs, a London‑based startup founded by former Monzo AI leaders, is deploying AI agents that act as dedicated account managers for bank customers. Using OpenAI’s GPT‑5.4 mini and nano, the system delivers 500‑millisecond latency for natural voice conversations and achieves high trajectory accuracy in complex banking procedures. The platform blends large models for reasoning with smaller models for deterministic tasks, routing based on complexity and latency, and runs 15+ guardrails to maintain compliance. Early deployments report CSAT scores up to 98% and over 50% resolution rates on day one, driving a ten‑fold revenue increase for the company.
