What we need is "just the right amount of numbers." Here is a guide to what works for me, and many of my colleagues.
Your numbers should be presented quarter-by-quarter over the first six or eight quarters after funding, and then yearly through year five.
If this is not your first round of funding then show the previous few quarters of history as well.
Please include these lines, adjusted as necessary for your business model.
Do NOT feel that you have to squeeze this into a PowerPoint slide with all the PPfluff (headers and footers) that squeezes this down to an eye-chart. Feel free to have a separate Excel spreadsheet handout which does not have all the extra nonsense. (See how I really feel about PowerPoint.)
When presenting your financials to VCs, you are revealing more than just a few numbers. You are showing that you understand (or don't):
Yes, all VCs discount your numbers, but do not use that as an excuse for unreasonable projections. Please, please, please tell me of any companies you have ever heard of that reach $100m of sales in year three of operations.
Yes, we may well want to see the gory multi-tabbed details later, but to
start with this one page summary would be great. Please.
