  • Audrey AI

    Led · Seed · Apr 2026

    Audrey AI develops an agentic AI platform purpose-built to automate key financial audit workflows, including intelligent data requests, evidence gathering, transaction testing, and automated review. The platform is designed to orchestrate tasks end-to-end and adapt to each audit firm's methodology, improving effectiveness over time. Founded in 2025 by Ryan Loughran and David Burke and based in Dublin, Audrey AI has piloted its solution with top-10 and top-20 audit firms. Pilots reportedly yielded more than 85% time savings in client data collection, validation, and tests of detail, as well as measurable improvements in audit quality. The company plans to use its newly raised pre-seed funding to grow its engineering and audit specialist teams and to scale deployments across Ireland, the UK, and additional international markets.

  • Vox Talk AI

    Led · Seed · Apr 2026

    Founded in April 2025 and based in Dublin, Vox Talk AI develops AI operators that work alongside human staff in monitoring centres, automatically taking over when alarms are raised. Its AI operators handle voice calls, log incidents, enter data, send emails and manage WhatsApp communications across hundreds of simultaneous alarms and in more than 30 languages. The platform already integrates directly with Sentinel and serves customers including Fenix Monitoring, Action 24 and G4S. Vox Talk AI reports its platform handles thousands of calls each month and that clients save over 50 hours of operator time weekly, with AI operators completing more tasks than humans and improving response times for high-severity alarms. The company plans to add computer vision capabilities for CCTV and video monitoring and to scale commercial adoption across Europe, the UK and the United States.

  • Kayna

    Led · Seed · Mar 2026

    Kayna, founded in 2021 by CEO Paul Prendergast and CTO Peter Bermingham, has built an infrastructure layer that allows vertical SaaS platforms serving small businesses—such as restaurants, franchise networks, construction firms, and field-service operators—to embed insurance offerings directly into their workflows. The company simplifies distribution for insurers and unlocks ancillary revenue for software vendors by integrating underwriting, policy issuance, and claims into existing software stacks. During its pre-seed phase (2023–2025) Kayna partnered with global broker Willis Towers Watson and launched live embedded insurance programs in the UK and US across cyber, equine, and security verticals, including a February 2026 launch with Belfry for the physical-security industry. It also rolled out an AI toolkit that automates insurance-policy analysis. Headquartered in Cork’s Penrose Wharf, Kayna has committed to creating 13 new roles and has already made senior hires in Ireland and the United States. The company’s near-term focus is expanding commercial operations in the UK and US markets, funded by its new seed capital. No revenue or user figures were disclosed in the article.
