Ruby startup demo – Chamod Gamage
summary
AngelList runs a single Rails monolith that has routed $15.44 billion to 28,000 startups and demos a concrete system: an open‑sourced Saxel library compiles a directed graph into Excel workbooks, Excel formulas become checks lifted into the datastore and are executed in an Excel cloud via a CRUD API, and a document parser using current LLM models cross‑checks filings to trace the exact cell or ledger entry that caused each discrepancy.
