Before you present a pitch, strategy, or board-adjacent deck, put the slides, the backup numbers, and the ask into one request and instruct the reviewer to attack every claim a skeptical buyer, investor, or operator would press. Do this from the chief executive or founder seat while a slide can still change.
This guide is for that private pass on a deck you will walk through. For a full board pack with appendix and prior minutes headed to directors, see reviewing a board pack before the meeting. For a staff-meeting proposal still shaped as an idea, see stress-testing a proposal before leadership. For a strategy memo you still control, see running a strategy memo through multiple perspectives. Executive starting points live under Pingpong for executives.
What a deck stress-test is for
A deck compresses a plan into a short sequence of claims. The room will treat one of those claims as the hinge: a win rate, a payback period, a competitive gap, or a cash figure. The drafting group already believes the hinge, so soft spots stay invisible until someone outside that group asks the first hard question. An adversarial pass names which slide would fail under that question, quotes the line, and points at the backup that does not support it. Keep the ask in one sentence, name the reader who can stop the plan, and attach the spreadsheet or contract excerpt the slides rely on.
A worked example
This example is illustrative and does not describe a customer. The chief executive of an 80-person software company has a 12-slide deck for Thursday's operating committee: pitch a paid partnership with a regional systems integrator, with a $900,000 first-year investment. Before the meeting, the chief executive puts five things into one request:
- The twelve slides and the one-page partnership economics sheet.
- Last four quarters of win rate and average sales cycle for deals that already involved a partner.
- The draft partner agreement excerpt that defines exclusivity and termination.
- The ask in one sentence: approve a six-month pilot with two named accounts and a go or stop review after the pilot.
- One instruction: read as a skeptical investor-observer and as the head of sales who will own the shared pipeline; list every claim the attachments do not support, quote the slide, and list the first five questions each seat would ask.
A review that helps points at concrete gaps. It might find that slide 4 claims partner-sourced deals close 20 points higher than direct mid-market deals, while the win-rate export only covers eight partner deals and mixes mid-market with enterprise. It might notice that the economics sheet treats exclusivity as optional while the draft agreement locks a twelve-month exclusive with a termination fee the deck never names. The chief executive checks each flag, replaces the 20-point claim with the eight-deal sample and a note that the gap is provisional, adds the termination fee to the economics slide, and names a capacity check at week eight.
A request you can copy
Below are a pitch or strategy deck I will present, the decision I am asking for, and the documents the slides rely on. Read the deck as [the skeptical reader in the room, for example a skeptical investor-observer, a chief financial officer, or a buyer who can walk]. List every claim the attached documents do not support, quoting the slide or line. Then list the first five questions that reader would ask aloud, and for each one say whether the deck already answers it and where. Rerun the main economics assuming [the assumption that matters most, for example that partner deals close at half the forecast rate] and tell me what changes on the ask slide. Don't rewrite the slides.
Leave the source files in even when the slides already quote them. Objections often come from a gap between a slide and the backup.
How the Pingpong web review app runs it
The web review app sends your request through several models in order. Each later model receives the original request and every earlier answer, with instructions to assess the work so far. An early pass might list unsupported claims by slide; a later pass might check whether a flagged number is wrong or only defined differently across files. You get a final answer and can open each earlier pass. A confident mistake in the first pass can carry forward, so check every flagged figure against the source file before you change a slide.
What a model review can't check
A model does not know which person in the room has already decided against the partnership, what was said in a hallway conversation last week, or which disclosure counsel already cleared. Legal, tax, accounting, and personnel matters belong with the person responsible for those answers before you present. Use the review to list questions and document gaps for those conversations.

If a finished package is headed to a vote or signature, see reviewing a high-stakes decision package. For a check on any draft, see getting a second opinion on a draft.
