BREAKING: AI can now build financial models like Goldman Sachs investment bankers (for free).

Here are 12 insane Perplexity Computer prompts that replace $200K/year IB analysts (actually from GS bankers)

(Save for later) 1. The Goldman Sachs DCF Valuation Model

"You are a VP-level investment banker at Goldman Sachs who builds discounted cash flow models for M&A transactions valued at $1B+ for the firm's most demanding Fortune 500 clients.

I need a complete DCF valuation model for a company built from first principles.

Build:

- Revenue projection: build revenue 5 years forward using bottoms-up drivers (units × price, users × ARPU, or segment-level)
- Cost structure modeling: COGS, SG&A, R&D, and D&A as percentages of revenue with trend assumptions
- EBITDA bridge: walk from revenue to EBITDA showing every line item's margin contribution
- Free cash flow calculation: EBITDA → taxes → capex → working capital changes → unlevered FCF
- WACC calculation: cost of equity (CAPM with beta, risk-free rate, equity risk premium) blended with after-tax cost of debt
- Terminal value: both perpetuity growth method and exit multiple method calculated and compared
- Enterprise value to equity value bridge: subtract net debt, minority interest, and preferred equity
- Implied share price: divide equity value by diluted share count including options and RSUs
- Sensitivity table: share price at 5 different WACC rates × 5 different terminal growth rates
- Football field summary: DCF range alongside comps and precedent transaction ranges on one visual

Format as a Goldman Sachs-style DCF model specification with every formula written out, assumption tables, and a valuation summary page.

The company: [ENTER COMPANY NAME OR TICKER, ITS INDUSTRY, AND ANY SPECIFIC REVENUE DRIVERS OR GROWTH ASSUMPTIONS YOU WANT MODELED]"

This is insane!!

An MIT student mastered an entire field in 48 hours using NotebookLM.

Same tool everyone has but used a completely different strategy.

Here's exactly how he did it: ↓ Most people use NotebookLM for summaries. Boring.

​He dropped in textbooks, papers, and a full lecture series.

​Then he ignored the facts and went for the "how."

“What mental frameworks do the top researchers in this field actually use to solve problems?”
