France's best-documented creator-audience launch in this dataset: Thomas Coget built the "l'Exceleur" Excel-education audience from ~2021 (TikTok 667K, Instagram 286K, courses, a book) then founded Elyx in June 2023 and sold it straight into that audience — the revenue chart is promo-spike shaped (Oct 2025 $16.3k, Feb 2026 $18.8k, $94 in between). Evergreen layers followed: a 6,600-URL bilingual pSEO estate and Microsoft AppSource certification. Now coasting: the founder disengaged, revenue slid to ~$600/mo partial, and the product is listed for sale.
The audience predates the product by two-plus years: 667K TikTok + 286K Instagram built as an Excel educator, product demos posted straight to it ("L'Agent IA Elyx: Le Nouveau Collègue Excel"). A 2022 podcast documents the audience-building arc independently.
6.6k bilingual (en/fr) URLs across 8 sub-sitemaps — /excel-formulas/{category}/{function} (~800+), /excel-errors/{error}/{function}, glossary and how-to clusters — long-tail Excel-help queries funneling to the add-in at DR 36.
Distributed as a Microsoft-certified Excel add-in via AppSource ("2-minute install", certification badges on-site) — marketplace rails inside the exact software the buyer already lives in; listing ratings unverified (page blocks fetches).
