The pre-seed financial stack: what to set up before your first investor call.

Investors decide a surprising amount in the first few minutes of looking at your numbers. Not because the numbers are big, at pre-seed they rarely are, but because clean financials signal a founder who runs a tight ship, and messy ones raise a question they will keep asking. The good news: the pre-seed financial stack is short, and most of it takes less than a week to set up. Here is the checklist we run with founders before they start talking to investors.

Why the stack matters before you raise

A raise is a diligence process, even an informal one. The moment an investor is interested, they ask for numbers, and how fast and how cleanly you answer is itself a data point. Founders who can produce a clean cap table, a simple model, and a current bank reconciliation on the same day look fundable. Founders who need two weeks to "pull it together" look early, regardless of how good the product is. The stack exists so you are always ready for that ask.

The eight pieces

1. A clean set of books. Incorporated, with business banking separate from personal, and transactions categorized in real accounting software. This is the foundation everything else sits on.
2. A simple cap table. Who owns what, including the option pool and any SAFEs or notes. It must be current and it must reconcile. Cap table confusion kills trust fast.
3. A bank reconciliation as of last month. Proof the cash in the books matches the cash in the account. It takes minutes when the books are clean and it is the first thing a careful investor checks.
4. A 13-week cash flow forecast. How long the money lasts, week by week, with assumptions stated. Investors want to know your runway before they ask anything else.
5. A basic operating model. A simple monthly projection of revenue, hiring, and spend for the next 12 to 18 months. Not a 40-tab masterpiece, a clear model whose assumptions you can defend.
6. Your burn and runway, current. One number for monthly net burn, one for months of runway. You should be able to say both from memory.
7. Corporate housekeeping. Incorporation documents, the minute book, IP assigned to the company (not held personally by founders), and contractor and employee agreements in place. Investors check that the company actually owns what it claims to.
8. The SR&ED picture. If you are building technology, know whether you have a Scientific Research and Experimental Development claim coming and roughly what it is worth. An expected SR&ED refund is real, non-dilutive cash that extends your runway, and sophisticated investors will ask.

What you can skip for now

You do not need audited financials at pre-seed. You do not need a full-time finance hire, a complex model, or GAAP-perfect statements. Trying to build those this early is a distraction. The stack above is enough to look credible and to run the company well. Add complexity when the business, and the next round, actually demands it.

The signal it sends

Founders are not judged at pre-seed on the size of the numbers. They are judged on whether they know their numbers. A founder who opens the laptop and answers "what is your runway, what is your burn, who owns the company, and is your IP assigned" without flinching has already cleared a bar most have not.

The stack is how you get there, and it is a week of work, not a quarter.
