The story of ÆTHERNA

ÆTHERNA was born from one concrete experience — our wedding, celebrated in Réunion Island in 2023 — and from another, professional one: my work as a project manager in renewable energy, where my role is to make projects happen despite tangled commercial, legal, financial and regulatory constraints. The two collided the day I tried to build the tool I wished I'd had.

A vertiginous starting point

Our adventure began with a calendar puzzle. The day after our engagement, my father-in-law called to lock in the date. Not in the coming weeks: the next day. And that's when it hit me what it actually meant.

Getting married in Réunion Island means juggling constraints that very few wedding guides ever address. Finding a date that honours both the Tamil religious calendar and the Christian one, while aiming for a precise weather window — the start of the austral winter, between April and June, to avoid the summer rains and the trade winds that pick up in July and August. All of that while steering clear of the month of the Virgin, considered unfavourable for new ventures, and waiting on the favourable dates the priests would identify for us. Before we'd even chosen a venue, the complexity was already there.

What didn't work

For everything else, we did what most couples do: we improvised.

Excel files multiplied for the seating charts — and even today, when I want to check who actually came, I get lost between the versions. WhatsApp and Messenger groups crossed paths constantly. My wife kept piling up handwritten notes. Financial tracking was non-existent at first, and looking back, if someone had told me upfront that we'd end up spending more than €20,000, I probably would have panicked.

We were extraordinarily lucky to have a deeply involved family that absorbed much of the mental load. But that's not everyone's reality. My in-laws had once told me they'd barely been able to enjoy my sister-in-law's wedding, eaten up by stress from start to finish. That image stayed with me. Sparing other families from ending up there became the underlying motivation.

From improvisation to project management

The first step was to set a framework — which doesn't come naturally to me. In daily life, I tend not to write anything down. As long as nothing slips, I'm fine. But the moment I forget something, there's no trace to fall back on — just that uncomfortable feeling that a detail is missing.

At work, I don't have that luxury. So I adopted the SMART objectives method (Specific, Measurable, Ambitious, Realistic, Time-bound). The golden rule in project management is straightforward: what isn't time-bound is unlikely to ever get done.

That's the logic I wanted to bring into ÆTHERNA. Letting future couples sketch the broad strokes first, with pre-set tasks, then dive into the details without ever losing sight of the bigger picture. Concretely, this turned into three pillars: task lists with deadlines and categories so nothing drifts; a Kanban view inherited from project management tools to make progress visible; and real-time tracking of budget and completed tasks — to measure the ground covered as much as what's left before the Jour J.

From idea to the platform I had in mind

The idea had been on my mind for a long time. At first, I imagined building the ultimate Excel file to track everything. But being very demanding on art direction, I quickly hit a wall. Asking a user to download a specific font just to make the file look right made the whole experience clunky. I tried no-code tools, and ran into the same aesthetic limits.

It was the recent rise of artificial intelligence that finally opened a new door. It allowed me to build, myself, the platform I had in mind — accessible anywhere, with no compromise on design.

What I hope for you

My in-laws couldn't enjoy their daughter's wedding as much as they deserved. They organised, double-checked, anticipated — and the day passed in a state of tension they still remember today. That's what I'm trying to spare you with ÆTHERNA.

Not to replace your family or a professional, but to centralise enough so that you no longer have to juggle scattered Excel files, handwritten notes, and WhatsApp groups. A travelling companion that lets you say: I'm staying here.
