proSapient operates an expert-networking platform connecting consultants and private equity firms with domain specialists for research calls and surveys. The tech stack—Elixir + Phoenix backend, Python + LangSmith + PromptLayer for AI, Kafka + Elasticsearch for data flow, and Kubernetes for orchestration—reveals a product heavily weighted toward matching algorithms and AI-driven content extraction. Active projects around recommendation engines and LLM-based data extraction, paired with pain points on expert recommendation and workflow automation, signal the core problem: surfacing the right expert for high-volume, niche client briefs at scale.
