Dessa

Dessa is an AI agent for ecommerce customer service and sales, built by the team at Trengo and operated by Trengo B.V. in Utrecht, the Netherlands. It learns a store's catalog and policies, answers order status and shipment tracking questions, checks returns against the store's return window, cancels or edits orders and delivery addresses before they ship, handles delayed orders, discount code problems and product questions, and recommends products to shoppers. It works inside the helpdesk a store already uses, including Gorgias, Zendesk and Trengo, and connects to storefronts such as Shopify, Magento, WooCommerce, BigCommerce, Lightspeed, PrestaShop, Shopware, Wix and Salesforce Commerce. Teams can start in Assist mode, where Dessa drafts replies for people to send, and switch to Autopilot mode when they are ready, with guardrails such as value thresholds, allowed actions and escalation rules. Dessa is priced per outcome in euros. Each successful outcome costs EUR 0.75, and the Grow plan is EUR 375 a month with 500 credits, dedicated onboarding, all integrations, unlimited agents and support by email and WhatsApp. An outcome is a resolved conversation, a conversation where the customer does not reply within 48 hours of Dessa's last answer, or a handover that the store's own rules asked for. Escalations, replies a team writes itself and conversations a person takes over are not charged. Unused credits do not roll over, a store that uses up its credits moves up one tier for the rest of the billing period, and yearly billing saves 15%. The price is the same with every helpdesk, and Dessa offers a free trial. Dessa suits small and mid-sized online stores that want an AI agent working inside their existing helpdesk. Stores that want one shared inbox across WhatsApp, email, chat and voice from the same company can look at Trengo. Stores that want a helpdesk built for ecommerce with its own AI agent can look at Gorgias. Teams outside ecommerce that want an AI agent billed per outcome on any helpdesk can look at Intercom Fin. Current state Q4 2026: Dessa has its own site, pricing and trust center, and its terms describe it as a product of Trengo B.V. Its trust center states a SOC 2 Type II report, ISO 27001 certification, GDPR processing with a DPA and EU data residency, and CCPA, with personal data redacted before any model call and a no-training guarantee. On its homepage Dessa reports 84% of conversations resolved autonomously and a 40-second median resolution time. Its FAQ says new connectors are added based on the needs of early access customers. No independent reviews of Dessa were found on G2, Capterra, Product Hunt or the Shopify App Store.
