Aveni, a fintech startup spun out of the University of Edinburgh, has raised £12 million in a growth funding round led by PXN Ventures, with participation from existing investors Puma Growth Partners, Lloyds Banking Group, Nationwide and Scottish Enterprise. The cash will accelerate development of Aveni's Unified Assurance Platform and fund the launch of two new products, Agent Assure and Agent Approve — tools aimed at assuring AI agents that interact with consumers in regulated financial services.
Why it matters
Agentic AI adoption in financial services is rising, but firms and regulators are wrestling with how to assure conduct and consumer outcomes when decisions are made by models rather than people. Aveni highlights a stark industry gap: only about 2% of firms report adequate AI guardrails, according to the figures it cites. Regulators such as the Financial Conduct Authority have been clear that whether an interaction is human or machine is less important than consistent consumer outcomes, and that is driving demand for monitoring and governance tools that can span both channels.
Aveni positions itself as a response to that problem, offering a framework for firms to monitor and manage conduct risk across human and agent interactions.
Inside the product
Aveni has built a suite of solutions used in live deployments across UK banks, wealth managers and financial advisers. Its core products today are:
- Aveni Assist: an AI productivity tool for advisers and operations teams.
- Aveni Detect: an AI compliance monitoring system that flags risky interactions or behaviour.
- Agent Assure and Agent Approve: new solutions described as extensions to Detect, designed to monitor, manage and formally approve the conduct of AI agents interacting with consumers.
- FinLLM: Aveni's proprietary set of specialist small language models trained on UK financial services data, which underpin its product set.
Together these components form what Aveni calls the Unified Assurance Platform — a single view to assess conduct risk across humans and agents. The company also participates in the FCA’s Supercharged Sandbox programme and has set up an Agent Assurance Expert Council to inform development of responsible AI governance standards.
Who are the investors?
The round was led by PXN Ventures. Existing investors Puma Growth Partners, Lloyds Banking Group, Nationwide and Scottish Enterprise also participated.
PXN’s involvement includes support through multiple PXN funds, including the Praetura Growth VCT, signalling continued backing from the North of the UK investor community. Puma Growth Partners invested again from its Scotland office and framed the deal as part of Scotland’s growing technology ecosystem. Lloyds Banking Group, which participates through its fintech investment arm, also renewed support.
In the announcement, Alastair Moore, Investor at PXN Ventures, said:
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.
In the announcement, Ben Leslie, Investment Director at Puma Growth Partners, said:
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.
In the announcement, Kirsty Rutter, Fintech Investment Director at Lloyds Banking Group, said:
Agentic AI represents a significant opportunity for financial services to enhance customer experience through more personalised interactions. Aveni is helping firms adopt this technology in a safe and responsible way. We're pleased to continue supporting Aveni's ongoing development through investment and partnership.

Founder perspective
Aveni was founded in 2018 and has spent seven years building live deployments and models specific to UK financial services. Its leadership includes co-founder and Chief Executive Joseph Twigg and co-founder and Chief Scientist Professor Lexi Birch, who also holds a professorship in Natural Language Processing at the University of Edinburgh.
In the announcement, Joseph Twigg, Co-founder & CEO, said:
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.
The bigger picture
This funding round sits at the intersection of two trends: increasing use of agentic AI in customer-facing financial services, and a sharper regulatory focus on ensuring consistent consumer outcomes irrespective of whether a human or model is involved. Tools that provide auditability, monitoring and formal approval workflows for models are becoming part of compliance roadmaps for many firms.
The deal also underlines interest from UK fintech investors in solutions that bridge product engineering and regulatory compliance, and it highlights Scotland’s expanding role as a hub for financial services technology.
Aveni’s raise and roadmap will be watched by firms and regulators across the UK and Europe as the industry seeks practical approaches to assure AI in regulated settings.
