Four platform layers stacked on a single rail, numbered in the order the loop runs them. 01 Intake, the data layer: the bedrock layer of structured data, extracted and organized from messy documents, spreadsheets, websites, articles and research reports. 02 Intelligence: models, benchmarks and reasoning that turn intake into judgment. 03 Feedback, the user layer: analyst overrides and LP-facing surfaces feed signal back in. 04 Agentic: agents that orchestrate, underwrite and act on the deal. A single marker runs down the rail, lighting each layer as it passes, then returns up the feedback arc carrying overrides, outcomes and corrections back to intake, which lights again. A chip beside the arc reads Closed Loop — learns, corrects, compounds — and the footer reads Loop active, 4 layers wired.
