Public operates a consumer investing platform spanning stocks, options, bonds, crypto, and retirement accounts. The tech stack reveals a dual engineering focus: native iOS/Swift development for the mobile-first consumer experience, and a sophisticated data platform (Snowflake, dbt, Airflow, Looker) paired with emerging AI/LLM tooling (OpenAI, Anthropic, Mistral, vector DBs like Pinecone and Weaviate). The project roadmap—data pipeline optimization, self-service analytics, AI-powered portfolio construction, and an "agentic brokerage" initiative—signals a shift toward autonomous trading agents and algorithmic investing features, moving beyond traditional brokerage tools.
