Bristol-based AI scaleup Narwhal Labs has raised £20m to coincide with the launch of DeepBlue OS, its autonomous platform designed to replace traditional customer communications with agentic AI.
Narwhal Labs builds enterprise-grade autonomous communications infrastructure for organisations spanning any size and sector. DeepBlue OS deploys AI agents across voice, SMS, email and WhatsApp, managing the full interaction lifecycle from first contact to qualified outcome without any human intervention.
The business operates on a utility model with zero setup costs, no long-term contracts and usage-based pricing. The newly-announced investment round was raised from over 70 UK investors, including Jonathan Swann, investor and former director of CFC Underwriting.
“Enterprise-grade AI should not be the exclusive preserve of organisations with eight-figure technology budgets and two-year implementation timelines,” says Luke Sartain, founder and CEO of Narwhal Labs.
“The level of backing we’ve seen reflects a growing recognition that this technology is no longer optional – it’s foundational to how organisations operate.”
DeepBlue OS operates autonomously 24 hours a day, handling enquiries, qualifying contacts, booking appointments, chasing documents, routing requests and executing follow-up workflows.
“What stood out about Narwhal Labs is that it’s providing an infrastructure that solves a clear commercial problem today, rather than creating experimental AI concepts,” adds Swann. “Every organisation loses revenue through missed or delayed responses, and this is scalable AI to solve that.”
