Is your website no longer generating leads, are your processes still manual, your data scattered, or can your application no longer handle the load? Since 2015, Wess Soft has been designing custom business software, web platforms, mobile applications and AI solutions in Lyon for SMEs, mid-sized companies, corporations and startups. 12 experts, a 100% French team, never offshore.

What we build Business software (ERP, CRM, invoicing): automate repetitive tasks, eliminate duplicate data entry and centralize your data. iOS and Android mobile applications (Flutter, .NET MAUI): equip your field teams, coordinate alerts and on-call duties, use geolocation, or launch a consumer-facing app. Web platforms, e-commerce sites and marketplaces: sell online, connect two audiences, give your customers a dedicated portal or a self-service quote configurator (WordPress or PrestaShop when they are sufficient, custom-built otherwise). Custom AI: a chatbot that answers your customers 24/7 and tracks their orders, agents powered by your documents (RAG), and anonymized personal data. Our approach We deliver in stages, starting with an MVP that your real users can validate or even use in production.
