What LXT does

LXT (legal name: Linguistix Tank Inc.) is a Canadian-headquartered AI training data services company founded in 2010 in Toronto. The company provides high-volume data collection, expert annotation, evaluation, and transcription services across text, audio, image, and video modalities, supporting generative AI, NLP, computer vision, speech recognition, and agentic AI applications for Fortune 100 enterprises and top global technology companies. Its core platform combines a managed services model (end-to-end delivery through dedicated project managers and ISO 27001-certified secure facilities) with a Crowd-as-a-Service offering, leveraging a vetted network of 8M+ contributors and 250K+ domain experts across 150+ countries and 1,000+ language locales.

LXT's business model rests on three revenue streams: (1) managed AI data services delivered via multi-year enterprise contracts with quote-based pricing, (2) usage-based Crowd-as-a-Service accessed through API and platform integration, and (3) transaction-fee-based self-service surveys launched through the December 2024 clickworker acquisition, which pay-per-response with no subscription. The combined LXT + clickworker platform, with integration completed in July 2025, supports the full AI data lifecycle including RLHF, supervised fine-tuning, red-teaming, and prompt engineering. The company holds ISO 27001, PCI DSS, HIPAA, and GDPR certifications, enabling secure handling of sensitive enterprise data. Primary customer segments are global technology companies and AI labs, with secondary verticals in CPG, healthcare, automotive, financial services, and government. Distribution is predominantly direct enterprise field sales, augmented by self-serve PLG channels and API/embedded integrations into client ML pipelines.
