The SaaS industry is still on a roll in 2025, and the UK is very much part of the momentum. Globally, SaaS revenue is expected to reach around £310 billion (roughly $390.5 billion) by the end of the year, with steady growth projected for years to come.
While the US leads in market size, the UK remains one of Europe’s strongest SaaS hubs, thanks to a mature tech sector, a thriving startup scene, and ongoing digital transformation across industries, from finance to healthcare to manufacturing.
SaaS isn’t new, but it’s now the default. Cloud-first strategies, remote work, and flexible subscription models have changed how businesses buy and use software. Instead of bulky installs or long-term licenses, companies want tools they can access from anywhere, scale easily, and pay for monthly.
Key growth drivers:
Not all SaaS categories are growing at the same pace. Some verticals are leading the charge by solving real, high-value problems across industries. Here’s a deeper look at where the action is:
Examples: Salesforce, HubSpot, Zoho
What it does: CRM software helps companies manage their entire customer lifecycle, from lead capture to post-sale support. It tracks customer data, automates workflows, and gives sales teams the tools to close deals faster.
Why it’s booming: Sales teams can’t afford to guess. CRMs centralise customer interactions and make them actionable. As competition heats up across industries, businesses are leaning heavily on CRM tools to drive conversions and personalise experiences.
Examples: Google Workspace, Slack, Zoom, Notion
What it does: These tools help distributed teams communicate, share files, manage projects, and stay organised.
Why it’s booming: Remote and hybrid work are here to stay. Companies need seamless, real-time collaboration, especially across time zones. Productivity SaaS is no longer a “nice-to-have”; it’s foundational.
Examples: Mailchimp, Marketo, Klaviyo, ActiveCampaign
What it does: These platforms help businesses to automatically send targeted messages to leads and customers via email, SMS, and social media.
Why it’s booming: Consumers expect personalised, timely outreach. These tools use customer data to drive smarter campaigns and better engagement without needing a massive marketing team.
Examples: QuickBooks, Xero, Stripe, FreshBooks
What it does: These tools handle everything from invoicing and payroll to expense management and payment processing.
Why it’s booming: Financial accuracy is critical, and manual processes are error-prone. SaaS solutions simplify compliance, automate tasks, and provide real-time visibility into a company’s financial health.
Examples: Shopify, BigCommerce, Wix, Squarespace
What it does: These platforms enable businesses to build, run, and scale online stores with minimal technical effort.
Why it’s booming: Online shopping continues to grow globally. These platforms give small businesses the same tech stack as enterprise retailers, with drag-and-drop ease and deep integrations.
SaaS is growing fast, and this has real implications, no matter what kind of business you run.
If you're operating a SaaS company, the market is still expanding, but it's more competitive than ever. To succeed, you’ll need a clear value proposition, strong customer retention, and smart pricing.
If you’re in a more traditional business, this growth means more tools are available to help you streamline operations, improve workflows, and scale.
For investors, the upside is still there, but the days of chasing hype are over. The best opportunities are with companies showing real traction, solid retention, and a clear path to profitability.
And if you’re building something new, SaaS is still one of the best business models out there. Getting a product live is easier than ever, but standing out and reaching the right customers is where the real challenge lies.
