Mosaic & Wellhub: Redefining Corporate Wellness Engagement

As a rapidly growing global specialty insurance platform, Mosaic Insurance operates an innovative, highly-digitised model that combines technical underwriting expertise with an agile, "people-first" culture. Today, the firm supports its global operations through a high-performing, interconnected team of 130 employees. However, traditional fitness subsidies fell short of supporting its diverse, hybrid workforce. Seeking an inclusive approach that went beyond one-size-fits-all corporate wellness, Mosaic partnered with Wellhub in January 2026.

Moving Beyond the "One-Dimensional" Benefit

Historically, Mosaic provided a traditional £40 monthly cash fitness contribution. While well-intentioned, the pre-tax stipend barely covered the cost of a basic gym membership in central London and offered minimal value globally. Mihir Raval, Global Head of HR Operations at Mosaic, recognised that a growing workforce demanded more flexibility. Mosaic’s HR team faced a clear set of challenges:

• Lack of Inclusivity: Traditional benefits only appealed to regular gym-goers, leaving out employees interested in mental health, holistic wellness, or boutique fitness.

• Geographic Limitations: Employees were often restricted to one specific gym branch near their homes or offices, offering no support for business travel or hybrid schedules.

"We recognised that employees have different lifestyles, schedules, and wellbeing preferences. We wanted to move beyond traditional, one-dimensional benefits and instead provide something that caters to a diverse workforce with varying needs."

A Flexible, Inclusive, and Practical Partnership

Mosaic chose Wellhub to transform its employee value proposition. Wellhub offered a centralised ecosystem providing access to premium boutique fitness studios, independent local gyms, mental health apps, and digital wellness services. From an operational perspective, the transition was seamless. The Wellhub team worked closely with Mosaic HR to coordinate timelines, align global internal communications, and execute a friction-free onboarding strategy.

Why Wellhub Stood Out:

• Hyper-Local & Global Variety: Access to thousands of fitness venues, ranging from nationwide full-service gyms, down to independent and niche boutiques.

• Holistic Wellness Ecosystem: Seamless inclusion of mental wellbeing support, nutritional apps, and recovery therapies alongside traditional fitness.

• Maximising Benefit Value: Instead of subsidising just one aspect of fitness, partnering with Wellhub provided a broader, multi-tiered wellness ecosystem for the same strategic focus, making the company’s investment much more impactful. 

The Impact: Unprecedented Engagement and Cultural Momentum

1. Hard Numbers: 82.7% organisation-wide subscription 

The launch defied standard corporate benefit benchmark figures. Typically, standard corporate gym and wellness programmes see an initial uptake of 20%  in month one, which sharply decreases to 5% by the end of the year one as engagement stagnates. Mosaic completely broke the mold. 

While registration rates across the workforce were exceptionally strong, the most compelling data point lies in how employees interacted with the platform. With an incredible 82.7% subscription rate, Mosaic’s team demonstrated that it found immense personal value in the premium, diverse offerings Wellhub makes available. 
This rapid uptake demonstrated a clear and previously unserved demand for a highly-personalised wellness benefit. Over their first six months, Mosaic’s employees achieved remarkable engagement across a highly distributed geographic footprint:

• 2,698 total wellness check-ins completed.

• 1,588 in-person gym and studio check-ins, capturing everything from local HIIT classes to recovery sessions.

• 1,107 digital app check-ins, showing strong utilisation of remote mental-health, nutrition, and wellness tools.

• Active utilisation across 17 different cities, proving the platform’s ability to seamlessly support a hybrid, global team regardless of where it works.

2. Eliminating Barriers to Entry

For individual employees, the financial and geographical barriers to holistic wellness disappeared overnight. Maddie, an Administrative Assistant based in London, points out how her personal routine drastically changed:

“Before Wellhub, my biggest barriers were time, cost, and location limitations. I would never pay for individual memberships to premium studios on my own—it was simply too much money. Now, I do Barry’s Bootcamp after work near the office on Mondays and F45 at a studio a five-minute walk from my house.”

3. Fostering a Collaborative, Connected Workplace Culture

Beyond individual fitness milestones, Wellhub sparked a grassroots social movement within Mosaic’s offices. In a corporate landscape heavily challenged by hybrid working patterns and Return-to-Office (RTO) friction, building a genuine sense of workplace community has become a primary hurdle for HR leaders. 

Wellhub’s global research highlights this trend, revealing that 51% of organisations link declining mental health directly to reduced productivity or performance, with widespread stress and a lack of workplace connection multiplying these risks. Mosaic directly addressed this challenge by using the platform as a cultural anchor. Teams began planning shared workout sessions, using the app to book classes together, and organically building cross-departmental togetherness. 

“Lots of people from work will go together. I have a group of people that will be, like, ‘Let’s try out this class together.’ We’ll go at lunchtime or we’ll go in the evening together. I think that’s a really nice social thing to do, and it is a good way to decompress after a busy day. It makes a big difference.” 

 — Maddie Dry, HR Administrator, Mosaic Insurance

The platform’s impact also extends far beyond traditional workouts, with employees heavily utilising Wellhub’s holistic wellness and recovery ecosystem.

Conclusion: A Strategic Blueprint for Modern HR Leaders

Mosaic’s success demonstrates that when organisations invest in employee wellness solutions that map directly to real human behaviour, engagement follows naturally. Supporting employees’ physical and mental health enables them to show up to work energised, resilient, and focused. For HR leaders looking to build a sustainable, high-performing corporate culture, Mihir offers clear advice:

“Choose a solution that offers flexibility, inclusivity, and strong employee engagement. When employees feel supported in their physical and mental wellbeing, they are more energised, resilient, and able to perform at their best. For me, it is about fostering a culture where people feel genuinely valued and supported, both in and outside of work.”
