Why scaling a SaaS should start from the ground up

Posted by Dominic Deacon in Insights

At this year’s Climb25, IDS Group’s commercial director, Dominic Deacon, returned to the stage to deliver a follow-up session titled ‘Code, cloud, and clarity’, diving into what it really takes to scale a SaaS business in today’s environment.

If you’re a founder, operator, or investor in SaaS, here’s what Dom unpacked, and why now, more than ever, your tech partnerships could be the secret to unlocking growth.

Let’s be honest, growing a SaaS business today is harder than ever. Investor scrutiny is higher, budgets are tighter, AI is transforming user expectations and technical complexity, and whether you’re pre-Series A or post-Series C, enterprise customers demand scale, security, and reliability from day one.

That’s why more SaaS businesses are turning to strategic tech partners. 

But a true technology partner doesn’t just build to spec, they understand your product vision, challenge your assumptions, and help you scale with intention.

In his talk, Dom stated a simple truth, “you cannot scale a SaaS business on shaky technical foundations.” 

At IDS, we’ve seen too many fast-moving startups reach a growth ceiling because the underlying tech simply can’t keep up. Think:

  • Single-tenant systems posing as multi-tenant
  • Lack of observability and automated testing
  • Fragile infrastructure with no redundancy
  • Critical knowledge held by one engineer (who’s now left the company)
  • Technical debt so high it triples your delivery time

Sadly, these are common issues, and can end up costing a business time, money, and momentum.

So what does a scalable platform look like in 2025?

  • Modular, extensible architecture
  • Cloud-native deployments with cost controls
  • Security baked in for your specific vertical
  • Clean, well-documented, test-covered code
  • Observability and alerting across the stack
  • A roadmap informed by data, not gut feel

And most importantly, a partner who helps you balance tech debt vs delivery, cost vs performance, and growth vs stability, each day.

We’re product-minded, cloud-native builders who think commercially and move at startup speed. We help you balance trade-offs between cost, speed, scalability, and long-term value.

Through our partnerships with AWS and Ingram Micro, we also offer co-funded cloud migrations, cost optimisation support, and go-to-market help via the AWS Marketplace.

One SaaS client brought us in just before their Series B. Over six months, we helped modularise their platform, implement cost controls, automate deployments, and create a roadmap for international expansion. They closed their round, landed enterprise clients, and now operate in three regions on a platform built to scale.

So, if you’re building or backing a SaaS business, the big question is, will your tech be ready for what’s next?
