ETTravel Tech Stack

Travel consultancy with enterprise AI/ML infrastructure

Travel Arrangements London 11–50 employees Privately Held

ETTravel operates a traditional travel consultancy (airline, hotel, rail, visa, corporate incentive bookings) but the tech stack reveals a parallel, data-heavy engineering operation: Scala, Java, Python, Go, Rust across AWS, GCP, and Azure, with LLM inference, Databricks/Delta Lake pipelines, and model monitoring. The hiring mix (engineering-heavy, mostly senior/lead roles) and active projects (LLM judge ecosystem, end-to-end ML pipelines, model compliance) suggest a hidden software or AI-as-a-service initiative distinct from the travel booking surface.

About ETTravel

ETTravel is a London-based travel consultancy founded in 1995, operating as an independent travel services firm with in-house ticketing and 24/7 support. The company serves three verticals: entertainment, corporate, and individual travel, offering airline and hotel bookings, domestic and international rail, car hire, visa services, conference and incentive travel, and private jet arrangements. Unusually for a travel agency, the company maintains a substantial engineering and data science operation across AWS, GCP, and Azure, with active work on LLM infrastructure, ML pipelines, and model compliance—suggesting a move beyond pure travel brokerage into software or AI products.
