What 3S holding OÜ does

3S Holding OÜ is a privately held Estonian AI boutique founded in 2022 and headquartered in Tartu, operating with a 1–10 person team. The firm delivers AI consulting, applied research, and machine learning solutions to enterprise clients, with a stated portfolio of 100+ deployed AI solutions. Leadership comprises Prof. Shahab Anbarjafari (Founder and Board Member), a machine learning scientist and Professor, and Mr. Adam Jafari (Chair of the Board), a mathematician and machine learning engineer. The company pursues a horizontal go-to-market serving "general businesses" across multiple industries via enterprise field sales and direct consultation.

The company's core technology stack is built on four pillars: advanced AI research, mathematical modeling, signal processing, and machine/deep learning. It claims multimodal capabilities across text, image, and audio, and lists generative AI, predictive analytics, optimization, process automation, knowledge retrieval, and autonomous-agent research as capability areas. Open-source software and open-research publishing are positioned as deliberate strategic choices, supported by 200+ scientific publications and 300+ invited talks. Strategic long-term bets include Human-AI Interaction research and an AGI (Artificial General Intelligence) initiative described as a "moonshot."

Revenue mechanics are professional-services-based: custom AI solution development and deployment, with no disclosed pricing, no listed products, no app store presence, and no API or SDK distribution. The company operates from a single Estonia headquarters with a global channel claim but no disclosed geographic expansion. No funding rounds, M&A, partnerships, customers, certifications, or revenue figures are disclosed in the input data.
