Replatforming for growth: supporting Preventx to scale and diversify

Preventx is the UK’s leading provider of sexual health testing services, with operations spanning the UK and the Netherlands. Trusted by the NHS and private providers alike, Preventx operates its own laboratory and digital platforms to deliver at-home testing services at scale. With rapid growth and new investment, the business needed to modernise its technology foundations to support diversification and expansion into new markets.

Preventx’s existing systems were largely home-grown and monolithic. While bespoke development had enabled them to meet specific customer needs and grow quickly, the platform had become increasingly complex.

Key challenges included:

• Difficulty making changes without knock-on impacts elsewhere.
• Lack of clear change management processes, leading to competing priorities and inefficiencies.
• Limited ability to assess the commercial viability of new opportunities before committing resources.
• Increasing operational risk as the business looked to scale into new geographies and products.

Preventx needed a new platform and stronger governance to enable sustainable growth.

Answer Digital partnered with Preventx to:

• Architect and design a new platform — laying flexible foundations that could support UK operations immediately and open the door to international expansion.
• Introduce change management processes — enabling initiatives to be prioritised, assessed, and aligned with commercial goals.
• Embed best practice in delivery — providing architectural guardrails, roadmaps, and documentation to reduce wasted effort and increase development velocity.
• Bridge the gap between exec vision and technology delivery — acting as a trusted partner to align ambitious growth plans with practical, safe, and scalable technology execution.

Our team provided senior expertise in business analysis, architecture, and delivery leadership, working side-by-side with Preventx’s in-house developers and leadership team.

While Preventx’s US expansion plans did not progress commercially, the platform foundations we designed are now being embedded across the UK business, providing lasting value. Key outcomes include:

• New platform foundations that modernise legacy systems and support future scaling.
• Stronger governance and change processes, helping Preventx focus on viable opportunities and avoid costly missteps.
• Efficiency gains — for example, manual financial reports once taking hours each week are now automated, freeing leadership to focus on strategy.
• Improved collaboration between technology and commercial teams, with Answer consultants helping rebuild trust and strengthen relationships with customers.
• Private equity confidence — by providing visibility and assurance on technology and performance, we helped Preventx’s investors gain confidence in the company’s roadmap and spend.

Preventx’s story is a common one: a fast-growing, PE-backed business constrained by ageing systems and stretched teams. By bringing clarity, governance, and scalable technology foundations, Answer Digital helped bridge the gap between ambition and delivery.

For Preventx, this has meant moving from firefighting and saying “yes” to everything, to making informed decisions, avoiding risk, and building for sustainable growth. For their investors, it has meant increased visibility and confidence in the business’ future
