Pitch Deck Financial Projections: What Pre-Seed Investors Actually Check

Every founder eventually faces the financial projections slide — and most fill it with a hockey-stick chart that investors have learned to scroll past. Here's what pre-seed and seed investors actually check on that slide, a structure you can copy, and the honest way to project numbers for a company that barely has any.

What investors actually check (it's not the revenue number)

At pre-seed, everyone knows the projections are guesses. Investors read the slide anyway, because it reveals how you think. What they're checking:

1. The assumptions, not the outputs. $3M ARR in year 3 is meaningless; "500 customers at $500/month with 3% monthly churn" is checkable. If your slide shows outputs without assumptions, the slide says you don't know which levers matter.
2. Whether the math reconciles with the rest of the deck. If your market slide claims a $40M bottom-up TAM and your projections show $80M revenue by year 5, one of them is wrong and the partnership will find it in about nine seconds.
3. The cost side. First-timers project revenue and forget that revenue costs money. Show hiring plan, CAC, and burn — investors trust founders who know what growth costs.
4. Unit economics direction. Nobody expects positive unit economics at pre-seed. They expect you to know your CAC, your expected LTV logic, and which assumption you're testing with their money.
5. The milestone the raise buys. Projections should visibly connect to the ask: "this $500K gets us to $30K MRR, which is what a seed round requires."

The one-slide structure that works

For pre-seed, one slide, four elements:

• A 3-year table (not 5 — nobody believes year 5): revenue, customers, team size, burn, ending cash
• Your 3–4 driving assumptions, written on the slide: pricing, conversion rate, churn, CAC
• A milestone marker: where in the timeline the money runs out and what you'll have proven by then
• One sensitivity line: "if conversion is half our estimate, we reach the milestone 5 months later" — this single line signals more financial maturity than any chart

Projecting with no revenue history

Bottom-up, always:

1. Start from your funnel: visitors → signups → paid conversion → churn. Use your actual early data where it exists, and clearly-marked benchmarks where it doesn't.
2. Price × customers = revenue. Layer growth from a named acquisition channel with a capacity estimate, not a percentage plucked from air. "20% MoM" is a red flag when it isn't attached to a channel that can physically deliver it.
3. Costs: founders' below-market salaries, first hires with dates, infrastructure, and CAC spend consistent with the acquisition plan.
4. The result is a model where an investor can turn any dial and watch the effect — which is exactly what they'll do in diligence.

The consistency trap (and the tooling fix)

The most common failure isn't a bad model — it's a deck, a spreadsheet, and a memo that each tell a slightly different story after three weeks of edits. Deck says $12 TAM-derived ARPU, model says $15, memo says "premium pricing." Each artifact was right when written.

This is a data-plumbing problem, and it's fixable with tooling: in Founders360, the Financial Tools agent builds your projections from the same shared project context your Market Researcher and pitch deck use — and the deck's [Inject] placeholders pull the actual numbers from that shared context, flagging [DATA NEEDED] when a number doesn't exist yet rather than inventing one. One source of truth, three consistent artifacts.

Free template

Copy this table structure into a sheet (or let the free plan's agents generate it from your data):

| | Year 1 | Year 2 | Year 3 | |---|---|---|---| | Paying customers (EOY) | | | | | Monthly price (blended) | | | | | ARR (EOY run-rate) | | | | | Monthly churn % | | | | | CAC | | | | | Team size | | | | | Monthly burn (EOY) | | | | | Ending cash | | | |

Assumptions box (write these on the slide): pricing basis · conversion rate + source · churn estimate + source · acquisition channel + capacity.

If you can fill that table and defend every cell for 60 seconds each, your projections slide is ahead of most decks an investor sees that week.
