Language I/O

What Language I/O does

Language I/O is a Cheyenne, Wyoming-based software company that provides AI-powered multilingual customer support translation technology to global enterprises. Founded in 2011, the company enables monolingual support agents to communicate with customers across 150+ languages in real time, integrated natively into major CRM and support platforms including Salesforce Service Cloud, Zendesk, Oracle Service Cloud, ServiceNow, and Intercom. Named enterprise customers include Shutterstock, Eurostar, IntraLinks, Unit4, Checkr, and Rainbow Railroad, spanning travel, financial services, software, nonprofit, and BPO verticals.

The company's core technology is a multi-model translation platform that combines multiple neural machine translation (NMT) engines with large language models (Google Gemini, DeepL NextGen) through a proprietary Smart Model Selection engine. This engine evaluates every translation request, routes it to the best-performing model for the specific language pair and content type, and includes real-time quality scoring with automatic failover. Layered on top are a self-improving glossary (with 90% domain-term accuracy), a Translation Optimization pre-processor, a Toxicity Shield for agent protection, and Attachment Translation for image/PDF/document content. The platform supports text, audio, image, and multimodal translation across channels including live chat, email, tickets, voice, chatbot, and knowledge base. Differentiators include an extensive compliance stack — ISO/IEC 42001, ISO 27001:2022, SOC 2 Type 2, HIPAA, GDPR, CCPA, PCI DSS, and EU-U.S./Swiss-U.S. Data Privacy Frameworks — and a Zero Data Retention policy.

The business model is usage-based: enterprise customers purchase annual credit packages priced per word translated, with translation memory reducing repeat charges, no per-user or setup fees, and optional machine-translation-with-human-post-edit (MTPE) professional services. Go-to-market is enterprise field sales supplemented by marketplace listings on Salesforce AppExchange (4.9 stars) and Oracle Cloud Marketplace, plus a developer API and Chrome Extension for broader reach. The company has raised approximately $26.5 million across seven funding rounds from 2019 through January 2026, including an $8M Series A1 (2023) and $5M Series A2 (2024), and employs 51-100 people. Geographic expansion into Asia-Pacific and Latin America is publicly planned.
