What is Certainly?
Certainly deploys autonomous AI agents that handle customer conversations across web chat, WhatsApp, Instagram, SMS, email, and voice. Instead of scripted decision trees, the agents reason about goals, call tools in your stack, and resolve tickets end to end. The platform connects to Shopify, Zendesk, Salesforce, Gorgias, and 200-plus AI models with automatic failover.
Traditional chatbots break when customers go off-script. Certainly pairs agentic AI with implementation support from Copenhagen, where the company has operated since 2017. Customers like Feastables, Quad Lock, and Fintiba report containment rates above 40% and measurable revenue impact from post-chat purchases.
E-commerce brands, CX teams, and sales organizations use Certainly for customer support, conversational commerce, and internal ops. Starter plans begin at 500 euros per month with conversation-based billing and a 3-month pilot option.
