What Hemisphere Web does

Hémisphère Web is a privately held digital communication agency headquartered in Strasbourg, France, founded in 2012 by François Kirmann and Thomas Géhin. The firm operates five internal service pillars — SEO (référencement naturel), GEO (Generative Engine Optimization for AI search engines), SEA (paid search and social advertising across Google, Meta, LinkedIn, TikTok, and Spotify), community management / social media, and website creation (WordPress and WooCommerce) — alongside a professional training business. Its go-to-market is sales-led, combining inbound content marketing via an SEO-optimized blog, conferences and webinars (Bizz&Buzz, BioValley France, CCI Strasbourg '30min pour comprendre,' SEO Garden Party), and direct outreach through website contact forms, phone, and WhatsApp. Pricing is quote-based with a free pre-audit; GEO engagements range from €1,500 HT (audit) to €5,000-€10,000 HT (strategy) and from a few hundred euros per month (ongoing subscription accompaniment).

The agency primarily serves TPE/PME (small and medium enterprises) across Alsace, France, Switzerland, Germany, and Luxembourg, with selective large-enterprise engagements and a separate training audience of freelancers and corporate communication teams. Geographic footprint is delivered from the single Strasbourg office (4 Quai Kellermann). Hémisphère Web holds Google Partner, Meta Partner, and Brevo Partner Pioneer 2025 status, is an official 'activateur France Num' for SMB digital transformation, is referenced on DataDock since 2017 for OPCO-eligible training, and is a member of UCC Grand Est. Director Thomas Géhin is an internationally recognized speaker on SEO and GEO topics.

The firm's principal proprietary asset is its GEO methodology: a 5-step process spanning initial AI visibility audit, content enrichment, reliable citation build-up, structural readability (H1-H2-H3, Schema.org), and continuous monitoring across AI platforms, coupled with a Content Gap Analysis for generative engines and LLM-oriented netlinking. The agency reports completion of more than 100 projects per year. Headcount is described as a small team. No funding rounds, acquisitions, or external institutional investors are disclosed.
