A desk for the 10-K and the live tape.

Data Desk is a research surface for five mega-cap names. It reads the printed books, prices a textbook discounted-cash-flow model, and holds that number against the open market — then lets Grok talk through all of it.

Data Desk home — Apple headline against the live tape

Microsoft desk — Azure is the novel — Microsoft

NVIDIA 10-K print with mix events — The print

Data Desk terminal on the focused name — Terminal

The names

Switch the ticker. The desk rewrites.

Headlines, mix events, Grok starters, cash, debt, and the 10-K all belong to the focused name. Apple is not a skin on Microsoft.

Surfaces

One set of books. Every lens.

Live

Open quotes, reverse DCF, cash and debt from the latest print, headlines that refresh.

FY 2018–2025 on one board. Mix events rewrite themselves when you change the name.

Deck

Operating mix, cash machine, funnel, and peer pack — the same books, a different lens.

Terminal

awk, tables, scripts, and the same engines as the charts. On this device.

DCF

Five-year cash build, terminal value, equity bridge. Street vs. desk, vs. tape.

Monte Carlo

Shock WACC, growth, margins. Paths, sensitivity, forecast, history, risk.

Your desk

Sign in. Keep the assumptions.

Google, X, or email. The focused name, scenario, growth path, WACC, and notes save to your account so the next session opens where you left it.

Grok

Ask across the whole tape.

Grok reads the live quote, the 10-K mix, the DCF bridge, and the Monte Carlo tails for the name on the desk. Starters change with the ticker. The answer is an insight, not a screenshot of a chart.

Independent researcher and product builder. Data Desk is the successor to a single-name Apple DCF notebook: same obsession with the print, now a desk that can change names without changing its mind.
