About Rent4sure
Rent4sure provides specialist financial background checks for the lettings industry. Their platform supports thousands of property professionals across the UK, with uptime and performance critical to the success of their customers. As their business scaled rapidly, their legacy infrastructure — based on a rented virtual server — became a limiting factor.
The Challenge
Rent4sure’s existing hosting provider couldn’t keep pace with the company’s growth or technical needs. The virtual server setup lacked the resilience and scalability required for a business operating in a high-demand, high-availability environment.
Jack Webb-Heller, IT & Products Director, explains:
“Our business was growing and we needed the assurance that our back-end systems, used by thousands of clients across the UK, were not just able to cope with our growth but actually had the potential to scale with us.”
The team needed a technology partner who could guide infrastructure decisions, proactively identify risks, and ensure system reliability — all while supporting a lean, efficiency-focused operating model.
The Solution: A Long-Term Infrastructure Partner
Rent4sure engaged Tiger Computing in 2010 to design, manage and support a more robust hosting environment. Tiger began by setting up and migrating the platform to a series of virtual servers. As demand continued to grow, Tiger flagged that the virtual infrastructure was approaching its limits and recommended moving to dedicated hardware.
In 2014, Tiger designed and deployed a new dedicated server environment, complete with a virtualised disaster recovery fallback — ensuring continuity and scalability as the business matured.
“The team at Tiger is truly expert and continues to help guide us and help us navigate the multitude of potential options… They have enabled us to choose the best solutions for our business.”
Going Beyond Support: Strategic Input That Drives Change
Tiger’s proactive involvement went beyond infrastructure. Early on, they identified performance issues related to externally developed code. Rent4sure investigated and ultimately chose to bring development in-house — hiring Jack Webb-Heller to lead the rebuild of their core platform. That move led to the creation of a dynamic internal dev team that still runs the system today.
The Outcome: Confidence, Continuity, and a Trusted Partnership
Today, Rent4sure runs a lean, agile business — but downtime isn’t an option. Even a brief outage could cause delays for letting agents placing tenants in properties.
“If our system went down for even 10 minutes… it would stop our clients putting people into properties and so cause disruption all the way down the line.”
Tiger ensures that never happens. With expert Linux support, proactive updates scheduled around business hours, and a clear understanding of Rent4sure’s commercial needs, Tiger has become more than just a supplier — they’re a strategic partner.
“We count Tiger as one of our most trusted partners and absolutely recommend them.”
