About Narwhal Labs

Narwhal Labs is a Bristol-based AI scaleup that provides enterprise-grade autonomous communications infrastructure. Founded in 2022 by Luke Sartain, the company aims to make advanced AI accessible to organizations of all sizes, particularly targeting the mid-market and regulated sectors like financial services, insurance, healthcare, and government. Sartain previously founded and grew Narwhal Media Group, a digital marketing technology business, which informs the data-driven and automation focus of Narwhal Labs.

In April 2026, Narwhal Labs announced it had raised £20 million in a funding round backed by over 70 UK investors, including Jonathan Swann, a former director of CFC Underwriting. This funding coincided with the launch of its flagship product, DeepBlue OS. DeepBlue OS is an autonomous communications platform designed to manage the entire lifecycle of customer interactions without human intervention. The platform operates 24/7 across multiple channels, including voice, SMS, email, and WhatsApp.

The system functions through a multi-agent architecture. An inbound agent acts as an AI receptionist to handle calls and schedule appointments; a response agent engages with new inquiries within minutes; and an outbound agent manages follow-ups and re-engagement campaigns. DeepBlue OS is designed for full automation, differing from other tools that primarily augment human teams. Key features include handling enquiries, qualifying contacts, booking appointments, and executing follow-up workflows. The platform supports over 50 languages and integrates with existing CRM and case management systems. For developers and agencies, Narwhal Labs offers a marketplace where they can build and publish AI agents, earning royalties based on usage.

Narwhal Labs operates on a usage-based, pay-as-you-go pricing model with no setup fees or long-term contracts, making it accessible to businesses without large technology budgets. The company emphasizes security and compliance, holding ISO 27001 and SOC 2 certifications and adhering to regulations such as GDPR, TCPA, and OFCOM.
