Why "build or buy?" is the wrong question for AI-era software
For years, technology decisions have been framed as a binary choice: buy an off-the-shelf SaaS product, or invest in building something bespoke. It was a useful shorthand, but in 2026, that framing no longer holds.
AI is changing the equation - not just in what software can do, but in how quickly it can be built and how closely it can be tailored to the way your organisation actually works.
The investment is there. The returns are harder to find.
The numbers tell an interesting story. In our latest research, 93% of UK organisations are already investing in AI as part of their software infrastructure, and 95% plan to increase that spend. Yet 85% report significant challenges when it comes to implementation.
That gap - between intention and outcome - is where most businesses find themselves right now.
Investing in AI doesn't automatically translate into value. What it does do, increasingly, is expose the gaps that were already there.
AI as a diagnostic tool
One of the most striking findings from our research is that for 84% of respondents, the drive to adopt AI has surfaced problems they didn't fully anticipate. The most common? Data issues (29%), systems issues (28.6%), and cost pressures (27.3%), followed by people and skills challenges (22.2%).
This isn't a reason to slow down. It's a reason to be more deliberate. AI doesn't reduce the need for solid foundations, it makes those foundations more important than ever.
The organisations we see moving fastest aren't necessarily the ones with the biggest budgets, they're the ones who treat AI adoption as an opportunity to get the underlying architecture right: clean data, well-integrated systems, and software that's built around how the business actually operates.
Bespoke isn't what it used to be
There's a perception that custom software is slow and expensive, the preserve of large enterprises with deep pockets and long timelines. Generative and agentic AI is changing that.
Development cycles are compressing, the friction in translating a business requirement into working software is reducing, and, crucially, the experienced developers on our team can now spend less time on repetitive groundwork and more time on what actually matters: understanding the problem and designing the right solution.
The result is that tailored, AI-enabled software is becoming accessible to businesses of all sizes - not as a replacement for SaaS platforms, but as a way to build on top of them. To fill the gaps. To connect the systems. To create something that reflects your processes, your data, and your strategic goals.
From static tool to continuous capability
Perhaps the biggest shift we're seeing is in how businesses think about software itself. The old model was largely static, you built something, deployed it, and it stayed roughly the same until the next project.
What's emerging now is something different: software that adapts. That learns from the business. That gets better over time rather than gradually becoming outdated.
That's a significant opportunity. But it requires a different kind of thinking, and a different kind of partnership, to get right.
Where to start
If you're investing in AI and not yet seeing the returns you expected, the answer is rarely "invest more." It's usually about getting clearer on what problem you're actually trying to solve, and whether your current systems and data are in a position to support it.
To help organisations work through exactly that, we're offering a free AI readiness audit to assess your systems, identify opportunities and help turn AI investment into practical outcomes.
The question worth asking isn't "build or buy?" It's "what do we actually need, and what's the smartest way to get there?" That's a much more interesting question, and increasingly, it's one we can help you answer.
