Lisio

What Lisio does

Lisio is a French B2B software vendor headquartered in Castres that builds JavaScript plugins and accessibility services to make public-facing websites and intranets inclusive and environmentally lighter. The company was founded in 2017 (originally as Numanis, rebranded to Lisio around 2021) and operates three core offerings: Lisio Humanity, a personalization plugin that adapts website display to visitor needs including visual, cognitive, motor, and language-related disabilities, plus an Eco-Boost mode that reduces page weight up to 90%; Lisio Welcome, an instant translation plugin powered by DeepL Pro covering 30+ languages; and Lisio Conformity, a professional services line delivering RGAA accessibility audits, training, and compliance support. Lisio itself achieved 100% RGAA 4.1.2 conformity on the Humanity product following an AccessProd audit in May 2024 and holds the Numérique Responsable Level 1 label.\n\nThe business model is subscription-based software, supplemented by quote-based professional services. Lisio Welcome is sold via transparent monthly tiers ranging from €29 (Basic, 2 languages, 500K characters) to €99 (All-In, 30 languages, 2.3M characters), with freemium trials (1 week/50K characters) and self-service installation guides for WordPress, Joomla, PrestaShop, Drupal, and Google Tag Manager. Lisio Humanity follows a four-tier (Assist, Boost, Impact, Transform) quote-based subscription model with custom enterprise features and a 1-month free trial, and is also offered as a perpetual license. Lisio Conformity is sold as expert-led RGAA consulting on a custom-quote basis. Distribution runs through three named commercial directors managing enterprise demos and quotes, a HubSpot-scheduled demo funnel, and channel integrations with web agencies and integrators.\n\nThe customer base spans French public sector, social housing, tourism and hospitality, healthcare/insurance, energy, and nonprofits, with named logos including EDF, Harmonie Mutuelle, Sicoval (mutualized across 20 communes since 2019), Clésence, Ligue contre le cancer, Hellfest, Epsens, and France Mutuelle. Lisio states more than 500 websites are equipped in France. The company is privately held (SAS), with no institutional venture backing disclosed, a sole €100K participatory loan from EDF in 2024, and a planned 2025 funding round to support international expansion.
