What is Trengo?
Trengo is a customer engagement platform that combines an omnichannel shared inbox with AI agents for support and sales teams. Founded in Utrecht, the Netherlands, in 2015, it gathers WhatsApp Business, email, live chat, Instagram, Facebook, TikTok and voice conversations in one place. Teams use Trengo to answer customers faster, automate common questions and keep every conversation tied to the customer record.
Its AI layer includes AI Agents for repetitive questions such as order status and returns, AI Journeys for guided workflows and AI voice agents for calls. Trengo also offers Dessa, an AI agent for ecommerce brands, and a sales variant that qualifies leads and books calls. It integrates with Shopify, WooCommerce, HubSpot, Salesforce and several hotel systems, making it popular with European ecommerce and hospitality businesses.
