Show HN: I built a mini PowerBI for tech comps with no dev experience with Codex (gotham-web.onrender.com)

Built The Matrix, a mini PowerBI-style app for tracking public tech comps.

It covers a fixed universe of consumer and enterprise tech companies, refreshes hourly, and includes a sortable coverage table, Rule of 40 / valuation views, a Playground for custom charts, company drilldowns, and exports. Metrics include EV / Revenue, Rule of 40, EBITDA, gross margin, capex, and SBC.

I had no prior app-building experience and built it with Codex. Curious what HN thinks is actually useful here.
