73% of CFOs in the UK are optimistic about the impact of artificial intelligence on their businesses, according to Deloitte's latest survey. This figure marks a jump from 59% at the end of 2025 and 39% in previous years.
73% of CFOs from the largest companies in the UK express optimism about the impact of artificial intelligence on business performance, according to the latest Deloitte UK CFO Survey. This figure represents a significant leap from the 59% recorded at the end of 2025 and the 39% from previous years, marking a turning point in the financial sector's technological adoption.
For B2B startup founders selling automation or AI solutions for finance, this shift in mindset opens a critical window of opportunity: CFOs no longer see AI as an experiment, but as a strategic lever for efficiency and growth.
The Triple Pressure Accelerating AI Adoption in Finance
The acceleration is not coincidental. Financial departments face triple pressure: to reduce operational costs (AI can cut them by 20-40% according to industry data), to speed up decision-making in volatile environments, and to free up team time for strategic initiatives instead of repetitive manual tasks.
The UK data reflects a global trend. According to the State of AI in Finance 2026 report by CFO Connect, 56% of financial leaders worldwide are already using AI tools in their daily work, doubling from 31% in 2024. In Spain, adoption is even more aggressive: 76% of companies apply AI in financial planning, although only 21% have achieved measurable value so far.
Where CFOs Are Implementing AI in 2026
Use cases are concentrated in areas of high operational impact. In accounts payable, 54% of CFOs are already using AI to automate processes; in accounts receivable, 47% have implemented AI solutions; in ERP systems, 44% integrate AI into their core platforms; and in financial data analysis, 34% use advanced tools.
In terms of strategic initiatives, CFOs prioritise AI for investment analysis (39%), strategic planning (38%), decision-making improvement (37%), and risk management (37%).
86% of CFOs have already implemented AI in most or part of their decision-making processes, according to the Kyriba 2025 survey. However, only 42% have integrated it into most of their operational processes, revealing a gap between strategic adoption and tactical execution.
The Gap Between Adoption and Measurable Value: The ROI Challenge
Here’s the data every founder must understand: although 63% of financial departments globally are already using AI, only 21% claim to have achieved measurable value from those implementations. Even more revealing: only 14% have fully integrated AI agents into their workflows.
This gap explains why CFOs remain cautious about spending despite growing optimism. It is not skepticism about the technology, but a demand for demonstrable ROI. 60% of CFOs plan to increase their investment in financial AI by at least 10% in 2026, but condition that spending on tangible results in efficiency, automation, and decision improvement.
For startups looking to capitalise on this wave, the key is to demonstrate ROI in 6-12 months, not in three years. CFOs are no longer buying promises of long-term transformation; they want to see measurable impact in the first year. Structuring the value proposition around concrete metrics such as reduction in manual hours, decrease in errors, or savings in operational costs (the industry benchmark is 20-40%) is essential.
Moreover, prioritising integration over innovation is crucial. 43% of CFOs are still stuck in manual tasks despite the advancement of AI, according to 2026 data. They do not need another disruptive tool that requires changing their entire tech stack, but solutions that integrate with their existing ERPs (SAP, Oracle, NetSuite).
