Formation accelerates FanDuel Racing and TVG

The challenge

FanDuel’s Racing portfolio – which includes both FanDuel Racing (FDR) and TVG — faced the growing complexity of maintaining two brands across four platforms each: iOS, Android, Web, and Desktop. This meant eight distinct applications requiring consistent performance, design, and user experience, all while racing to meet customer expectations and regulatory demands.

Teams worked with fragmented design libraries and inconsistent component implementations. Maintaining parity between design and front-end systems proved difficult, leading to duplicated effort, mismatched styling, and growing technical debt.

Each shared component had to be validated across all eight applications, slowing down releases and consuming engineering and QA capacity.

Additionally, Racing products presented unique interface challenges – dense data displays and tight vertical space. Balancing consistency with the high-speed, information-rich nature of Racing’s user interface required precision and flexibility.

The solution

To solve these challenges, Mindera worked closely with the Racing and TVG technology teams in partnership with FanDuel’s Core Product Experiences unit to fully integrate the Formation Design System (DS) – evolving it from a toolkit into a strategic product accelerator.

The integration plan focused on four key pillars:

• Parity and Process Alignment – Establishing a clear bridge between design and engineering ensured Formation’s components performed consistently in production. A structured definition of core vs. page-level components helped control scalability and performance.
• Real-World Adaptation – Rather than enforcing idealized patterns, Formation evolved based on real product use cases. Components were validated against Racing’s live needs — from typography adjustments to tighter layouts – ensuring usability and adoption.
• Multi-Brand, Multi-Platform Enablement – Formation’s multi-product theming system allowed FDR and TVG to share foundations while maintaining distinct brand identities. React, React Native, iOS, and Android libraries ensured parity across all eight applications.
• Adoption Through Collaboration – Instead of mandating usage, the Formation team embedded within product squads, offering support, feedback loops, and documentation improvements. This fostered trust, alignment, and organic adoption.

By positioning Formation as critical infrastructure, FanDuel transformed it from a “support team” into the foundation of scalable, high-quality delivery.

The outcome

The results have been transformative:

• Accelerated delivery: Reusable Formation assets cut duplication and engineering hours dramatically – the Pill component alone saved ~300 hours across three teams. Scaled across 20+ high-usage components, Formation now avoids 6,000–9,000 hours annually, unlocking capacity for new features and innovation (across all FanDuel verticals).
• Consistent fan experience: Shared design tokens and accessible defaults ensure a cohesive, trustworthy interface across Racing and TVG, and the rest of FanDuel offers (SportsBook, Casino, Fantasy, …) strengthening brand recognition.
• Reduced technical debt: Accessibility, performance, and compliance improvements cascade across platforms – fix once, benefit everywhere.
• Strategic enablement: Formation now acts as a product multiplier, empowering FanDuel to launch faster, scale smarter, and evolve confidently into new markets and partnerships.

Formation’s success with FDR and TVG proves that a design system isn’t just a toolkit — it’s an investment in speed, quality, and the future of FanDuel’s digital ecosystem.

Key benefits

• Saved around 300 hours across three teams alone
• Avoids engineering effort of about 6,000–9,000 hours annually
• Scaled across 20+ high-usage components

Commenting on the project, Vivian Lam, Head of Tech at FanDuel Racing, said: "Formation isn't just a design system – it's become the backbone of our product velocity. Mindera's partnership in scaling Formation across eight applications saved us thousands of engineering hours annually. We're now shipping features weeks faster while maintaining absolute consistency across FanDuel Racing and TVG brands."
