Comstream Tech Stack

AI-driven staffing and talent platform connecting Swedish and Bulgarian tech hubs

Information Technology & Services Stockholm, Stockholm 51–200 employees Founded 2010 Privately Held

Comstream pairs a staffing business (recruiting and placing technologists across Sweden and Bulgaria) with emerging AI product work. The tech stack reveals a sharp pivot toward NLP and generative AI: the company is actively building and fine-tuning transformer-based models (GPT, BERT, T5, LLaMA) and integrating them into production systems, while also operating SaaS and gaming platforms. Engineering dominance (15 of 17 active hires) with mid-to-senior seniority suggests internal product development is scaling alongside the core staffing operations.
