A CEO we worked with last year opened her Series B model three weeks before her first partner meeting and found that marketing spend had been booked under four different line items depending on which month you looked at.
She spent the better part of a weekend just reconciling categories before she could even start building the forecast an investor would actually read.
She got the round done. It took longer than it should have, and two of the firms she wanted most passed before she ever got in the room, because her data room wasn’t ready when they asked for it.
That’s the version of this article. Six months out, not three weeks.
Month 6: Find out what’s actually broken
Start with the chart of accounts. Categorization drift happens to almost everyone we work with, not because anyone did anything wrong, but because nobody was assigned to keep it clean while the company was busy growing. Contractor costs split between COGS and opex depending on who entered the bill. A one-time legal expense sitting in a recurring line since March.
Then pull every forecast you built over the last twelve months and put it next to what actually happened. If revenue came in 15% under plan in Q2, you need to be able to say why in one sentence, not five minutes of hedging. Write down the gaps you already know are there. Missing headcount planning. CAC that isn’t broken out by channel. It’s a different conversation when you bring up the gap yourself than when an associate finds it for you in week three of diligence.
Month 5: Build the model you’ll actually defend
This is where most of the six months should go.
An integrated three-statement model means the cash flow statement is not a separate tab that someone built once and never touched again. It’s tied to the same assumptions as the P&L and the balance sheet, so when one number moves, the others move with it. Investors can spot a disconnected model fast, usually by asking to change one input and watching nothing else react.
Build the revenue forecast from the bottom up. Pipeline you actually have. Conversion rates you’ve actually measured. The market-sizing slide where you capture some small percentage of a large number stopped working somewhere around 2022.
Run a base, bull, and bear case, and write down what has to be true for each one. Not three lines on a chart with no explanation. What would need to change for you to hit the bull case, and what are you tracking right now to know which direction you’re actually heading.
Month 4: Get your unit economics right before you say them out loud
Decide once how you calculate CAC, LTV, payback period, and gross margin, then use that same definition every time you say the number, in every meeting, to every investor. Quoting two different CAC figures in the same process, even if both are technically defensible, is the kind of thing a partner remembers.
Build a cohort view that actually shows the trend. If your last few cohorts are retaining better than the ones from a year ago, that’s worth its own slide. Buried inside a general metrics page, nobody sees it.
Run the comps. Know roughly where your margin, growth rate, and burn multiple land next to companies at your stage, so you’re not doing that math for the first time out loud in a meeting.
Month 3: Package what you’ve built
The financial work should mostly be done by now. This month is about the story around it.
A model doesn’t sell a round on its own. Somebody still has to explain why this amount of capital, spent this way, gets the company to the next real milestone. Build the data room index before anyone asks for it: financial statements, cap table, customer contracts, cohort data, prior board decks, organized the way a VC actually expects to find them.
Then have someone who isn’t you try to break the model. A board member, your fractional CFO, a founder friend two rounds ahead of you. Better to find the soft assumption in that conversation than in the one with the fund you actually want.
Month 2: Ask yourself the hard questions first
What happens to burn if growth slows by a fifth. What’s the plan if your largest customer churns. What if the sales hire you’re counting on takes three extra months to ramp. Sit with these before an investor asks them cold.
And get specific about the cash need. “Eighteen to twenty-four months of runway” is not an answer investors trust anymore on its own. Tie the number to what it actually buys: the hires, the market, the metric that moves because of it.
Month 1: Bring the board in before the investors
Your board should see the model and the narrative before either shows up in a partner meeting. Walk them through it. Let their questions be the last round of pressure-testing before the real thing.
Get the investor update template ready too, along with answers to the questions you already know will come up more than once. Once the process is live, you’re sending the same update and fielding the same handful of questions from several investors in parallel, and there won’t be much time to draft from scratch.
