Background
Founded in 2009 by Andrey Akselrod and Jack Welde and headquartered in New York, New York, United States, Smartling (smartling.com) is an enterprise AI translation management system (TMS) and language services platform built for global digital brands across technology, e-commerce, travel, and financial services. Operating with a team of 51-200 employees after raising $223.3M across seven funding rounds from lead investors including Techstars, Venrock, First Round Capital, Felicis, and Battery Ventures—and backed by majority private equity owner Vitruvian Partners—the company automates continuous localization across websites, mobile apps, marketing campaigns, and customer support repositories. Rather than managing manual spreadsheet handoffs to regional translation agencies, global marketing teams use Smartling to localize digital experiences continuously.
How Smartling works
Smartling operates at Level 3 autonomy by combining its cloud Translation Management System and Global Delivery Network (GDN) proxy with its multi-engine AI Hub. When new marketing copy, web pages, or product strings are published in source systems such as HubSpot, Salesforce, Shopify, Webflow, Braze, Intercom, or Zendesk, Smartling automatically detects changes, captures visual layout context, and checks centralized Translation Memory and brand glossaries. Its AI Hub then dynamically selects the highest-performing combination of 20+ large language models and neural machine translation engines for each specific domain and language pair, applying automated prompt engineering, glossary injection, and AI Linguistic Quality Assurance (LQA) checks before routing high-visibility assets to optional human post-editors. The platform operates under SOC 2, ISO 27001, GDPR, and HIPAA security certifications.
