Hello Tomorrow Global Summit

3,500+attendees
80+exhibitors
30+strategic partners

An international deep-tech summit.

Two days live. Months in the making.

the work happened before.

For months before the doors opened, my work sat somewhere between partners, exhibitors, internal teams, suppliers, the venue and the digital platform. I helped turn hundreds of individual requirements, deadlines and moving pieces into one experience that had to feel seamless once people arrived.

The operational detail

Every detail had somewhere to land.

Exhibitor requirements, operational questions, last-minute changes and the decisions connecting them all lived in the working material long before they appeared on site.

Making the space work

A floor plan isn't just where things go. It determines how thousands of people move through an experience. Stages, exhibition areas, networking spaces, catering, signage, partner areas and VIP routes all had to coexist without feeling like separate pieces.

My work involved translating those requirements into practical decisions with the venue, internal teams, partners and suppliers — and continuing to adjust them as the event evolved.

Making people work together

The Summit wasn't one team delivering one event. It was dozens of groups needing different things at the same time.

Each of the 80+ exhibitors and 30+ strategic partners arrived with their own needs, constraints and deadlines. I was where those requirements turned into briefs, deliverables and timelines — and where questions, changes and last-minute problems landed before they could reach the event floor.

The details nobody sees

Trussing.
Cables.
Flight cases.
Again.

A raw venue, trussing going up, cables run across the floor, flight cases stacked against the wall — days of production work built to disappear the moment the doors opened.

Production. Infrastructure. The work behind the experience.

still part of the job.

My role: Platform owner

The event had a digital twin.

While the physical Summit was being built in the venue, another version of it was being built on screen.

I was the person on the Hello Tomorrow team directly managing the event's networking platform. I configured the experience, structured attendee categories and VIP segmentation, managed content and user data, coordinated technical changes with the external Grip team, tested the platform and supported its rollout before the Summit went live.

The goal was simple: the digital experience had to understand the same people, priorities and connections as the physical event.

From plan to place

Same event.
Two realities.

I see everything it took to make it happen.

Inside the experience.

Once the Summit went live, the work changed. Plans became real-time decisions: helping attendees, sending session and panel reminders, troubleshooting the networking app, answering questions and handling whatever came up along the way.

Startup Validation Program

Before events, there were programs. At ACIE in Beirut, I helped manage a startup validation program built around founders, experts and an ecosystem that had to keep moving together.

That meant planning the program from the inside — finding and coordinating the experts who worked with the startups, keeping founders informed and moving through each stage, creating the content that told the program's story, and doing the sector research that grounded it all.

Outside the CV

Currently: in the kitchen

Lebanon · currently

A completely different kind of operation.

After working behind the scenes of a 3,500-person summit, I somehow ended up behind a completely different kind of counter.

I'm currently working in a Japanese professional kitchen in Lebanon. Different environment. Still a lot of pressure, precision, teamwork and timing.

Turns out, I like knowing how things work from the inside.

About

I like the part where everything has to come together.

I'm Mariebelle Ziade. I work across project management, events, marketing and brand experiences, usually in environments where there are a lot of people, moving parts and deadlines to keep aligned.

I've worked between Paris and Lebanon, across international events, startup programs, digital platforms and, unexpectedly, a professional kitchen. Different environments have taught me different things, but I keep gravitating toward the same kind of work: understanding the whole picture, connecting the people involved and making sure the idea survives contact with reality.
