Charles Co
Charles (charlesAI, hello-charles.com) is a Berlin-based conversational commerce and CRM platform that lets brands sell, market, and support customers over WhatsApp, Instagram, Facebook Messenger, and Webchat. Founded in 2019, the platform connects chat-app APIs (WhatsApp Business, Messenger) with e-commerce and CRM systems such as Shopify, Salesforce, SAP, and HubSpot, and layers AI agents over them to automate the full funnel from acquisition and conversion to retention while staying GDPR compliant. Charles exposes a token-authenticated HTTP API organized around per-tenant "universe" hosts, a public Postman workspace, and a (now deprecated) JavaScript/TypeScript browser SDK published to npm. It was surfaced as a portfolio lead of Speedinvest and enriched into the API Evangelist network from its public developer surface.
Charles Co publishes 1 API on the APIs.io network. Tagged areas include Company, Conversational Commerce, Messaging, WhatsApp, and CRM.
Charles Co’s developer surface includes authentication, documentation, API reference, engineering blog, support, signup flow, and 15 more developer resources.
