Nathan describes model architecture before formulas, sanity-checks every data input, and applies the same variance commentary structure every time - amount, budget, percentage, driver. Every model includes a base case and a downside as a minimum. Single-scenario models are not models. They are guesses.

- → Variance analysis and commentary - budget vs actual with amount, budget reference, percentage, and primary driver stated every time - in the format boards and investors expect
- → Business cases and ROI frameworks - NPV, IRR, payback period, make vs buy vs lease analysis, pricing change P&L impact, capital expenditure justification, headcount scenario models
- → Revenue and commercial analysis - segment, product, geography, and customer breakdowns, cohort analysis, gross margin by product line, pricing and volume trade-off modelling
- → SaaS metrics and unit economics - ARR, MRR, NRR, churn, LTV:CAC, Rule of 40, burn multiple dashboards built and interpreted with the precision tech finance requires
- → Management reporting - monthly pack outlines, board meeting financial materials, KPI dashboard designs, rolling forecast frameworks, and investor-ready financial summaries

Questions about this product
What does the Nathan skill do?+
Nathan builds financial models, produces investment analysis, and creates the FP&A outputs — variance analysis, scenario modelling, and board-ready financial reporting. Load once into Claude Projects and get a configured Financial Analyst without explaining context at the start of every session.
How do I install this skill file?+
Download the .md file, paste the full contents into Claude Projects Instructions, add your business context, and start your first session. Works with Claude, ChatGPT, or any AI chat accepting system prompts.
Which AI tools does this skill work with?+
Works with Claude (recommended), ChatGPT, and any AI chat accepting system prompts. Claude Projects gives the best results — the skill is optimised for Claude's instruction-following capabilities.
What is included in this download?+
One .md skill file delivered instantly after purchase. Contains the full role configuration, expertise context, and behavioural rules. No subscription required — yours permanently. Works with Claude, ChatGPT, or any AI chat.
How is this different from using Claude without the Nathan skill?+
Without a skill file, Claude starts every session as a general-purpose assistant. With Nathan loaded, Claude applies Financial Analyst expertise and methodology from the first message — no re-explaining, consistent quality every time.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
