Yaroslav Krempovych — Co-Founder

I build repeatable enterprise outcomes at the intersection of AI, data platforms, and governance—especially in regulated environments (pharma, banking, energy). At Billennium, I scale a modular portfolio from pilot to product: portfolio strategy, pricing & packaging, evidence‑based roadmaps, cross‑functional execution, and EU‑aligned governance. Previously I led $17M in AI/ML investments (driving $90M+ follow‑on), founded and shipped fintech products, and published NLP research with MIT/Stanford collaborators (100+ citations). Notable results: RAG‑based support deflecting 15–20% of 100K+ monthly queries; OCR pipelines processing 10K+ docs/month; 3 launches with Ministry of Finance certification readiness in 6 months (typical: 12–18); company‑wide AI workshops for 120+ employees. What I ship: portfolio strategy, pricing/licensing, governance frameworks, KPI dashboards, sales kits, and delivery playbooks. Keywords: Enterprise AI • Data Platforms • Integrations • LLM/RAG • LLMOps • AI Governance & Compliance (EU) • GTM Enablement • Regulated Industries.

Stackforce AI infers this person is a Fintech and AI Product Management expert with a strong focus on regulatory compliance.
