AETHERNA's answer:

Planning a wedding means making more than 50 decisions over 12 to 18 months, across dimensions that have nothing in common with each other — logistics, finance, emotion, geography, family. Most couples handle this with a Google Sheet for the budget, a Notion page for the to-do list, and a paper calendar for vendors. Everything desynchronized. That's how my wife and I planned our own wedding in Reunion Island in 2023 — 150 guests, three tools that never agreed with each other, and decisions made twice because we couldn't find the first version anywhere. ÆTHERNA started as a side project in 2025 to fix that for the next couple I cared about, which turned out to be more than two. I work in renewable energy by day and build ÆTHERNA on evenings and weekends, with a clear philosophy: an organization tool where your emotions have a place.

AETHERNA's answer:

Most wedding planning tools come from product teams. ÆTHERNA comes from a real wedding. It was built after my own wedding in Reunion Island in 2023, when I'd spent the year before fighting a Google Sheet, a Notion page and a paper calendar — and trying to keep my wife and me on the same page in the process. ÆTHERNA is one of the only French wedding planning platform native bilingual French/English, designed as a collaborative space — couples first, then anyone they involve in the planning (a wedding planner, a sibling, a parent) — with a design thought to accompany its users without stressing them.

AETHERNA's answer:

Four things distinguish ÆTHERNA. It's natively bilingual French and English from day one — most US tools have rough French translations, and French marketplaces don't offer a real planning tool. It centralizes the six tasks that actually drag in wedding planning — seating plan with drag-and-drop and capacity alerts, real-time budget with category breakdown, unified digital RSVP, 12-to-18-month timeline with reminders, detailed Jour-J coordination, and head-table layout. It's built for collaboration with the people who matter — your partner first, but also a wedding planner if you have one, a sibling helping with the seating chart, or a parent contributing to the budget. Most planning apps treat the couple as a single user; ÆTHERNA treats them as a team. And the free tier is real: up to 50 guests, no time limit, no credit card.

AETHERNA's answer:

Engaged couples planning their own wedding, typically aged 25-40, with 100 to 200 guests. They want a collaborative tool they can share with the people who matter — a wedding planner if they have one, a sibling helping with the seating chart, a parent contributing to the budget. The audience is mostly French and English speaking: French couples underserved by US-only tools, English-speaking couples looking for a design-focused alternative to mainstream platforms, fully integrated and thought out by for most commun issues they run into. A dedicated wedding planner tier is in development, built on the same collaborative foundation, although it's bringing exclusive features imagined to enhance their business.
