Aveni is redefining how financial institutions use AI.

We have been recognised as Fintech of the Year for two consecutive years and awarded Best Specialist Technology Service at the Professional Adviser Awards 2025. Backed by leading investors including Puma Private Equity, and commercially supported by Lloyds Banking Group and Nationwide Building Society, we previously completed one of Scotland's largest Series A rounds. Since then, we've continued to grow rapidly as adoption of AI in financial services accelerates, and we're now scaling our engineering organisation to meet that demand.
