The sixth edition of ReThink HK was held last September 11-12, where Hong Kong’s sustainability community gathered at the Hong Kong Convention and Exhibition Centre (HKCEC). This two-day event united government, business, investors, innovators, and NGOs to accelerate real-world progress on net-zero and ESG. It reinforced ReThink’s role as a city-level forum for sustainable business, featuring a diverse programme across multiple stages and a large solutions expo.

For EnviroEvents HK, the organizer, this edition was as much about connections as it was about content. With over 9,500 attendees and 300+ of sustainability solutions on display, the goal was to help participants discover practical innovations and meet the right partners to move their sustainability initiatives forward. 

To achieve that at scale, the organizer needed a partner capable of turning a complex mix of content, entitlement tiers, and exhibitor needs into an intuitive, high-value attendee journey.

Turning Complexity into Clarity

ReThink HK arrived with a set of real operational challenges that would have slowed many teams — but for EnviroEvents HK , they became an invitation to reimagine how a single, web-based platform could power the whole experience.

Key constraints the organizer faced:

• A dense content programme: 150+ sessions spread across nine theatres/stages, meaning discovery and scheduling had to be friction-free for attendees.
• A large expo of sustainable solutions: roughly 300 exhibiting companies needing discoverability and meeting access.
• Complex entitlement structure: Over 30 ticket and exhibitor groups, each with distinct access rights and privileges, required detailed configuration and management.
• Tight timelines: Business matching launched just two weeks before the event, limiting the adoption and engagement window.
• Integration and email deliverability challenges: Planned API integration with a third party vendor faced some challenges, requiring the team to use a backup method. At the same time, changes made to improve email security briefly disrupted email delivery during setup.

These realities shaped the plan: deliver powerful matching and content discovery while keeping everything manageable for an organizer using Jublia for the first time.

“Web-First, People-Centered” Approach by Jublia

Rather than lead with features, Jublia treated the project as a partnership: Jublia’s Customer Success teams worked side-by-side with ReThink HK to translate event needs into an operational blueprint. Key components of that blueprint were delivered entirely via the Web App — demonstrating how a well-designed web experience can handle large, multi-track events.

To support their goals, the organizer adopted Jublia’s Web App, powered by a full suite of engagement solutions. Jublia worked closely with the organizer from the early stages of planning to ensure a smooth setup process. The Customer Success team provided extensive training sessions, helping the organizer’s team become confident in managing the platform directly on Sense.

This collaborative and hands-on approach ensured the event platform was ready to perform, even with tight timelines and last-minute adjustments.

Providing a Seamless Digital Journey

One of the most complex aspects of the event was handling the multiple entitlement tiers. Each group had different privileges, such as access to certain sessions or meeting arrangements. To accommodate this, Jublia configured multiple group tiers with distinct entitlements, ensuring every attendee type experienced the platform as intended.

While the original plan involved full API integration, both teams worked closely to adapt when changes in exhibitor tiers required flexibility. Some data was manually uploaded to maintain accuracy and ensure a stable system throughout setup.

At the same time, the agenda builder process became a great example of teamwork in action. With hundreds of sessions to upload, Jublia’s team collaborated closely with the organizer to fine-tune the new bulk upload feature. Through quick coordination and shared problem-solving, the process was completed smoothly and efficiently.

From Collaboration to Results

Once the platform launched, engagement began gradually but gained significant traction as the event drew closer. During event days, ReThink HK successfully recorded over 60% fulfilled meetings. Attendee feedback was equally positive, with 80% reporting favorable experiences on the platform.

These results reflected more than just numbers. They highlighted how ReThink HK transformed from a large-scale sustainability forum into a connected ecosystem where attendees could network meaningfully, exhibitors could find relevant leads, and content could be easily discovered.

A Case of Sustainable Collaboration in Action

ReThink HK 2025 proved that sustainability and technology go hand in hand. Through a combination of smart digital tools, adaptive workflows, and strong teamwork, the event delivered measurable impact under tight timelines.

For Jublia, this collaboration showcased the power of flexibility, responsiveness, and partnership in helping organizers bring complex visions to life. ReThink HK 2025 stands as an example of how event technology, when paired with shared commitment, can accelerate meaningful connections and sustainable progress across industries.
