### Ada

Ada is the Agentic Customer Experience (ACX) company that helps organizations build, manage, optimize, and scale AI agents for customer service, with more than 550 AI agents deployed globally. Ada's core differentiator is the ACX Operating Model: the only approach in the category that pairs an enterprise AI platform with structured methodology and expert guidance. The logic behind it is direct: the best customer experiences come from businesses that own and operate their AI agents, not ones that depend on vendors to run them. The companies that own their AI capability are the ones that compound value. Ada's job is to help them get there. Ada delivers that ownership through three components: - ACX Platform: AI agent management across every channel and language, no engineering dependency required - ACX Practice: A structured methodology for building, governing, and scaling an ACX program - ACX Experts: Who work alongside internal teams to build lasting AI fluency The ACX Platform is designed with these core components: - Reasoning Engine™: An unified intelligence layer that powers the AI agent across all CX channels using shared customer context, business logic, and configurable policies, with built-in accuracy and safety controls. Consistent experience meets reduced overhead. - Conversation Hub: Deploy an AI agent across voice, messaging, email, and custom channels in 60+ languages, with structured handoff to human agents when escalation is needed. - Performance Center: Tools for building, testing, and optimizing AI agent behavior, including Playbooks for complex multi-step workflows (refunds, rebookings, authentication), Coaching for continuous improvement, and Simulations for safe pre-launch testing. Tracks resolution rate, CSAT, NPS, and custom KPIs. - Developer Toolkit: Pre-built connectors for Salesforce, Zendesk, and ServiceNow, plus APIs, SDKs, and an MCP Server for managing the AI agent from tools like Claude or ChatGPT. - Enterprise-grade security: SOC 2 Type II, GDPR, HIPAA, PCI DSS, and AIUC-1 certified, with Zero Data Retention and regional data residency. Ada was the first ACX platform to have achieved AIUC-1 certification, the world's first AI safety standard specifically designed for customer service agents—and Ada helped write it. Proven customer outcomes include: - IPSY (ecommerce) achieved 943% ROI on its AI investment within four months of using Ada's ACX platform alongside a 63% improvement in automated resolution rate and a 41% improvement in CSAT. - Endy (retail) achieved an 85% automated resolution rate during a major national promotion and 75% CSAT during their warehouse sale. - eSky Group (travel) saw a 17-point increase in automated resolution in four months, a 19-point CSAT jump, and 200% ROI—running three brands across 50+ markets with one team on one platform. - Blackhawk Network (fintech) transformed into a mature ACX operation, automatically resolving ~50% of all incoming inquiries across brands and channels, and upskilling frontline agents with plans to expand AI across the entire enterprise. Ada is built for enterprise organizations with high-volume support operations across industries including financial services, telecommunications, retail and ecommerce, travel, insurance, and technology.
