Aveni lands £12m in funding led by PXN Ventures to monitor consumer-facing AI agents in financial services

Aveni builds AI compliance and productivity tools for regulated financial services firms, including banks, wealth managers and financial advisers. Its platform monitors conduct risk across human and AI agent interactions with consumers, underpinned by proprietary language models trained on UK financial services data.

Aveni, an AI compliance and productivity platform for regulated financial services, has raised £12 million in funding led by PXN Ventures, with participation from existing investors Puma Growth Partners, Lloyds Banking Group, Nationwide and Scottish Enterprise. The investment will accelerate development of Aveni's Unified Assurance Platform and the launch of its new Agent Assure and Agent Approve solutions.

Founded in 2018 as a University of Edinburgh start-up, Aveni has spent over seven years building live deployments and proprietary models for UK financial services. Its two existing products - Aveni Assist, an AI productivity solution for advisers and operations teams, and Aveni Detect, its AI compliance monitoring tool - are deployed across the UK's leading banks, wealth managers and financial advisers. Underpinning both is FinLLM, Aveni's proprietary suite of specialist small language models built for and utilising UK financial services data.

Agentic AI adoption in financial services is accelerating, but deployment at scale is being held back by a critical gap in assurance. With just 2% of firms reporting adequate AI guardrails, the absence of robust, regulated oversight for AI agents that interact directly with consumers is described as the number one challenge for the industry. Regulators have made clear that the mode of engagement - human or machine - is secondary to consumer outcomes, which must be assessed consistently across all interactions.

Agent Assure directly addresses this gap. A natural extension of the Aveni Detect proposition, it enables firms to monitor and manage the conduct risk of AI agents alongside human interactions in a single unified view. Together with Aveni Assist, Aveni Detect and the new Agent Approve solution, it forms the Unified Assurance Platform: the financial services industry's first comprehensive framework for assuring both human and agent interactions with consumers at scale.

Aveni is a participant in the FCA's Supercharged Sandbox programme and has established the Agent Assurance Expert Council to support development of responsible AI governance frameworks. The company is working directly with regulators and industry bodies to shape the emerging standards for AI in financial services. Lexi Birch, co-founder and Chief Scientist at Aveni, holds a professorship in Natural Language Processing in the School of Informatics at the University of Edinburgh.

The continued confidence shown by our existing investors is a powerful endorsement of the direction we're taking. We have spent seven years building the models, the experience and the regulatory relationships that make us uniquely qualified to solve the hardest problem in AI adoption right now: how do you assure the conduct of an AI agent interacting with a real consumer? Agent Assure is our answer - and this investment accelerates our ability to deliver our full platform at scale.

Aveni is fast becoming financial advisers' go-to tool for helping them leverage AI in a safe and appropriate way. The team now has seven years of live deployments and proprietary models built within the UK financial services sector. Their infrastructure is answering one of the biggest questions in AI adoption: how to manage real client interactions and build trust, so advisers can focus on what they do best. We're proud to support Aveni through multiple PXN funds, including the Praetura Growth VCT, as they continue their growth journey and demonstrate the world-class fintech capabilities of the North of the UK.

The impact Aveni is making in deploying AI into UK financial services is already significant, and we continue to see a substantial growth opportunity ahead. With agentic AI adoption accelerating and regulators rightly focused on consistent consumer outcomes, robust assurance for AI agents is rapidly becoming a core requirement for the sector. As a standout example of Scotland's growing strength as a technology hub, Aveni is well placed to lead this next phase. We are delighted to invest again from our Scotland office to support Joseph, Jamie, Professor Lexi Birch and the wider team as they scale the Unified Assurance Platform and launch Agent Assure.
