TechFin is an AI-powered personal finance dashboard that doesn't just track your stocks — it reads the world. By aggregating news across multiple sources, performing deep sentiment analysis, and mapping relationships between global events and financial sectors, TechFin gives retail investors the kind of macro-awareness that used to be reserved for institutional traders.

Most retail investors react to the market. TechFin helps you get ahead of it.
TechFin is world-event-focused. It identifies like most mentioned geopolitical world events, mergers and acquisitions, as well as government macro-policy announcements to find the the most up to date investor sentiments related to the affected sectors, and quickly makes investment suggestions.
At its core, TechFin uses a custom knowledge graph (powered by Neo4j) to model the relationships between news articles, world events, sectors, and tickers. This enables intelligent graph traversals that surface the most contextually relevant insights for each event — not just the loudest headlines, but the most connected ones.
On top of that graph sits a LangGraph multi-agent AI chatbot that can answer natural-language questions about your portfolio, current market themes, and recent events by querying the knowledge graph in real time. Ask it "What's happening with NVDA?" and it pulls live, structured data — not hallucinations.
