   The Hook

   Codex Spreadsheet Introduction

   “(No spoken dialogue — The track begins with a glitchy, distorted electronic sound, followed by a sustained, evolving pad. A subtle sub-bass drop occurs at 0:01. A high-energy riser builds from 0:04 to 0:05, culminating in a percussive impact and a short, sharp electronic sound.)”

   Problem Definition & Codex Interaction

   “(No spoken dialogue — Another sub-bass drop is heard at 0:05. A sustained, ethereal pad with a slight tremolo effect continues. A subtle, high-frequency electronic 'ping' sound is present at 0:08. A low-frequency hum and atmospheric textures are maintained. A distinct electronic 'click' sound is heard at 0:10.)”

   What should we work on in spreadsheets? You are an investment banking analyst and have just been tasked to put together a waterfall analysis to understand ownership and returns for founders and existing investors. Your client is a startup considering a Series C investment round. Please find attached the template you will be modifying. I've added necessary assumptions in Column G. Column C names are repeated for indexing purposes in the Common Stock Section. Assumptions include Equity at Exit, Series Investment Amount, Fund Ownership, Warrants, Liquidation Preference, Conversion Price, Common Diluted Shares and Strike Price. Assume Seed, Series A and Series B are pari-passu non-participating preferred shares (i.e., investors in these rounds are all treated equally; have equal footing and claims on a borrower's assets). Auto-review spreadsheets Working I'll inspect the spreadsheet structure first so I can Thinking Ask for follow-up changes Working for 2s I'll inspect the spreadsheet structure first so I can map the assumptions in column G into the waterfall model clearly. Then I'll modify the workbook directly and sanity-check the formulas rather than guessing at the template layout. Ran pwd Exploring Listed files I found a single workbook: VC_Returns_Waterfall1_Input.xlsx ...I'm going to read the sheets, dimensions, existing formulas, and the assumption block so the edits preserve the template's intent. Thinking Ran 2 commands The template has the cap table assumptions filled in, but most of the waterfall body is still just row labels. I'm reconstructing the formulas across the exit columns now: liquidation preference, conversion/common distribution, investor summaries, and MoM outputs. Ran 3 commands I'm about to write the workbook formulas now. I'll save a completed copy so the original input stays intact, and I'll hide the small helper area used for the preferred conversion logic. The completed workbook has been written. I'm doing one more pass now to validate formula coverage and catch obvious spreadsheet issues like missing formulas, bad references, or totals that won't reconcile after Excel recalculates. Ran LibreOffice Ran soffice Ran 3 commands One reconciliation detail popped up: because option exercise proceeds are included to calculate the common share price, the common proceeds check should reconcile to remaining exit equity, not to the gross distributable pool including strike proceeds. I'm correcting that now. when opened in Excel and kept the helper logic hidden below the model. LibreOffice wasn't available locally, so I validated the workbook structure/formulas with openpyxl rather than a live spreadsheet calculation engine.

   Codex Spreadsheet Completion & Validation

   “(No spoken dialogue — A soft, almost imperceptible electronic 'whoosh' is present at 0:14. A subtle, high-pitched electronic 'chirp' is heard at 0:17. The ambient pad continues to evolve with slight modulations. A very subtle, almost subliminal electronic 'thump' is present at 0:20. A soft, sustained electronic 'swell' is heard at 0:23. A subtle electronic 'flicker' sound is present at 0:26. A very faint electronic 'pulse' is heard at 0:29. The soundscape gradually fades out, maintaining its ethereal quality. A final, subtle electronic 'shimmer' is present at 0:32.)”

   Worked for 3m 2s Done. I created the completed waterfall workbook here: VC_Returns_Waterfall_Completed.xlsx I filled the waterfall formulas across exit values, including pari-passu non-participating liquidation preference treatment, conversion/common distribution logic, options and warrants, investor proceeds, share-class proceeds, and MoM summaries. I also set the workbook to recalculate when opened in Excel and kept the helper logic hidden below the model. LibreOffice wasn't available locally, so I validated the workbook structure/formulas with openpyxl rather than a live spreadsheet calculation engine.
