OBHOLZ SOLUTIONSEVA Voice
Multi-tenant voice chatbot. One script tag. Replaces FAQ + contact form.
What it is
Customers talk to your website. EVA understands intent, answers from your knowledge base, hands off to humans when needed. Currently in private beta.
What the client asked for
Internal experiment: can a single AI agent replace 80% of the questions that hit a contact form? Can it sound human enough that users prefer it? Can it scale to N tenants with their own voice and knowledge?
Scope delivered
Every project ships with its full scope. No phase-2-promises, no 'foundation laying' invoices for empty product.
