Anticipating the Grand National, the UK’s premier betting event, Coral aimed to refine its digital betting platform to perfection. Recognizing the event’s potential to dramatically influence user engagement and platform performance, Coral sought a software development partner with deep iGaming expertise. Symphony Solutions emerged as the ideal collaborator, bringing their extensive knowledge to lead Coral’s application modernization efforts. Although the Grand National served as a critical catalyst for this initiative, the enhancements implemented were strategically planned for lasting impact, ensuring benefits that would extend far beyond the event itself. 



Coral, a renowned household name in the UK and one of the country’s largest bookmakers boasts a history dating back to the mid-1800s. With a visible presence on every high street in the nation, Coral established itself as a leader in the UK’s gaming and betting industry.  

As of March 2018, Coral became part of the Ladbrokes Coral Group after its GVC Holdings acquisition. This significant development transformed Coral into a key player within the world’s largest online betting and gaming company, operating under the umbrella of an FTSE 100 global organization. The acquisition magnified the importance of Coral’s digital platform, especially in the highly regulated UK betting market, where competition was fiercer than ever. 


Implementing Coral’s application modernization posed significant challenges for Symphony Solutions. The application modernization challenges included: 

  • Coordination and Communication: With multiple Scrum teams spread across different locations and time zones, ensuring seamless communication and coordination was crucial to keep the project on track. 
  • Dependency Management: The complex nature of the platform required meticulous application modernization approach. There was need for careful management of dependencies between teams. Also, prompt identification and resolution were essential to prevent delays and conflicts. 
  • Resource Allocation: The project demanded a strategic balance in resource distribution. It was important to ensure that both the development of new features and the resolution of technical debt were addressed effectively. 
  • Product Backlog Management: Managing a shared product backlog to reflect the project’s overall goals, while incorporating inputs from various teams and stakeholders, presented a challenge. This required continuous alignment and adaptability to evolving requirements.
