How Harmonic Rebuilt Scout on Deep Agents and 4x'd Retention with LangSmith

Harmonic's platform, originally designed as a venture capital sourcing tool, has evolved into a versatile resource for investors tracking private market trends, with its AI-powered assistant, Scout, serving as a conversational interface for data queries. Initially built with a rigid architecture, Scout's first version faced challenges in adapting to user demands for personalized and complex queries. This prompted a shift to a more flexible system using Deep Agents and LangSmith, significantly enhancing its capabilities and simplifying its architecture. The new version of Scout functions more like a trusted advisor than a traditional search tool, capable of integrating firm-specific context and providing comprehensive insights, such as investment thesis alignment or meeting preparation. This transformation has led to a fourfold increase in user retention and expanded the platform's market reach beyond investors to include innovation teams, recruiters, and others interested in startup ecosystems. Scout's improved user experience and adaptability have positioned it as an industry-standard tool in venture capital and related fields.
