Your Finance Partner for Clarity and Scale
Darren’s Story
I founded CFO IQ with one mission: to bring enterprise-standard finance to startups, scale-ups, and SMBs — powered by AI.
Over 25+ years, I’ve worked as a Finance Director, FP&A leader, and CFO across technology, gaming, transport, and global industries. I’ve scaled revenues from $200m → $600m, led international expansions, and delivered M&A integrations.
But I saw a gap: smaller, fast-moving companies rarely had access to the same tools, insights, and finance discipline as corporates. That’s what CFO IQ was built to change.

Philosophy
- Finance should enable growth, not slow it down.
- AI isn’t a replacement — it’s an accelerator.
- Founders need more than spreadsheets — they need decisions.
What Sets Me Apart
→ Track Record: Revenue growth, global expansions, M&A, and investor readiness across multiple industries.
→ AI Expertise: Member of the AI Finance Club, implementing automation, forecasting, and analytics at scale.
→ Practical Experience: From IGT International to Cambridge Electric Transport, I’ve advised boards and CEOs in real-world, high-stakes environments.
→ Outcome-Driven: Every engagement is about measurable impact — from reducing reporting cycles to securing funding.


Selected Achievements
- Amplified IGT International revenue from $200M → $600M pre-pandemic.
- Implemented AI-enabled reporting, reducing reporting time from 10 days → 2 days.
- Built SaaS subscription pricing models that accelerated global recurring revenue.
- Supported a seed-stage founder to secure a £1.2m raise with investor-ready packs.
