You have built something real. Revenue is growing. The team is in place. And you are ready to raise.

So you put together a pitch deck, tighten the narrative, and walk into the first investor meeting with confidence.

Then the questions start.

Not about the vision. Not about the market. About the numbers. Specifically, about the assumptions behind the numbers, the model beneath the deck, and whether your FP&A process is strong enough to actually deliver the plan you are presenting.

This is the moment most founders realise they have been preparing the wrong thing.

A compelling story gets you the meeting. A credible FP&A function gets you the term sheet.

This guide is for founders and finance leaders preparing to raise in 2025 or 2026 who want to understand exactly what investors look for when they go beyond the deck and into the detail.

Why FP&A Has Become Central to the Investment Decision

Investor expectations have shifted significantly over the past two years.

According to Beauhurst's 2024 State of UK Startup Investment Report, the average due diligence process for early-growth fundraises in the UK now takes 14 to 18 weeks, with financial model scrutiny consistently cited as one of the most time-intensive stages. That timeline has lengthened as investors have become more disciplined about where capital goes.

The era of funding growth on narrative alone is behind us.

According to McKinsey's research on performance management in scaling organisations, investors at every stage are placing significantly more weight on the quality of a business's financial planning and analysis capability as an indicator of execution risk. A business that cannot clearly explain its financial drivers is, in their view, a business that does not fully understand itself.

The FP&A function is not just the source of the numbers investors review. It is the evidence that the business has the infrastructure, discipline, and clarity to deploy capital effectively and grow with intention.

What Investors Are Actually Looking For

When an investor opens your financial model, they are not just checking whether the numbers add up. They are asking five questions.

For a direct view on where founders fall short on this, Powdr's Investor-Ready in 2025: What Founders Get Wrong and How to Fix It covers the most common gaps in detail.

The FP&A Process Investors Want to See Behind the Model

Most founders treat fundraising preparation as a modelling project. Build a three-year forecast, populate the deck, prepare for questions.

That is the wrong frame.

What investors are really assessing is not the model itself. It is the FP&A process that produced the model and that will continue to operate once the investment is in.

A one-off model built for a fundraise signals that the business does not have an ongoing planning function. It signals that the numbers in the deck may not reflect how the business is actually managed day to day. And it signals that post-investment, there may not be the financial infrastructure to track performance against the plan that just secured the funding.

This is what separates businesses that raise on strong terms from businesses that raise on weaker terms, or do not raise at all.

Building the Investor-Grade Financial Model

The financial model you present in a fundraising process needs to do two things simultaneously. It needs to be credible enough that an investor trusts the numbers. And it needs to be transparent enough that they can understand exactly how those numbers were produced.

Most fundraising models fail on the second point. They are sophisticated enough to impress at first glance but opaque enough to create doubt under scrutiny. Hardcoded assumptions buried in formulas. Revenue growth rates that do not connect to any commercial logic. Cost lines that appear without explanation.

For businesses where the model is being built to support a specific raise, Powdr's The Power of Strategic Clarity in Business Financial Forecasting provides important context on why the model needs to align with the broader strategic narrative, not just the financial mechanics.

The Due Diligence Process: What to Expect

Most founders underestimate how deeply investors will interrogate the FP&A function during due diligence.

It is not uncommon for a serious investor to spend three to five sessions working through the financial model in detail. They will test assumptions against market benchmarks. They will ask for the historical data that supports forward projections. They will request reforecasts under different scenarios. And they will ask to understand the FP&A process itself, not just the outputs.

According to the British Business Bank's 2025 Small Business Finance Markets Report, businesses that enter due diligence with a clearly documented financial planning and analysis process close rounds significantly faster than those that construct their financial story reactively during the process.

According to PwC's 2024 Finance Effectiveness Benchmarking Report, businesses that present investor-grade FP&A outputs during fundraising are 60% more likely to close at or above their target valuation than those that present reactive or incomplete financial information.

That statistic alone should determine how seriously you treat this.

The Questions You Need to Be Able to Answer

Before entering any investor conversation, every founder and finance leader should be able to answer these questions immediately and with confidence.

Common Mistakes in Fundraising FP&A

Building the model for the raise, not for the business. A model constructed specifically to look good in a data room, disconnected from how the business is actually managed, will be identified in due diligence.

Presenting a single scenario as a plan. One set of projections is not a plan. It is a hope. Investors know this. If you do not present scenarios proactively, they will ask for them.

Ignoring the cash flow model. The cash flow model is where investors assess whether the business can actually fund its growth plan between investment rounds. Powdr's Why Profitable Manufacturers Still Struggle with Cash Flow illustrates exactly how this plays out.

Underpreparing for assumption challenges. The founders who handle this well are not the ones with the most sophisticated models. They are the ones who know their assumptions cold.

Treating FP&A as a fundraising exercise rather than an ongoing function. The most credible signal you can send to an investor is that the FP&A process existed before they asked about it.

A Final Thought on What FP&A Signals to Investors

An investor is not just buying into your revenue projections. They are buying into your ability to execute.

A mature FP&A function is one of the clearest signals that a business knows how to execute. It demonstrates that leadership understands the financial drivers of the business. That the team has the discipline to plan, forecast, and adapt. And that the business has the infrastructure to deploy capital effectively and account for it rigorously.

In 2026, that matters more than it has at any point in the past decade.

The businesses that raise on the best terms are not always the ones with the highest growth rates. They are the ones that can explain their growth, defend their assumptions, and demonstrate the planning function that will ensure the next chapter of the business is built on solid financial foundations.

That is what FP&A is for. And that is what investors are looking for when they go beyond the deck.

A Few Things People Often Ask

How far in advance should I build my FP&A function before starting a raise?

At least six months before you plan to enter conversations with investors is the honest answer.

That gives you enough time to get a rolling forecast in place, run at least two or three monthly variance cycles, and build a model that reflects how the business is actually managed rather than one that has been constructed specifically for the raise.

Investors can tell the difference. A model that has been lived in, updated against actuals, and refined over time looks materially different from one that was built in three weeks under the pressure of a looming investor meeting.

If you are already inside six months, do not wait. Start now and be transparent with investors about where the FP&A function is in its development. That honesty, combined with evidence that you are building it properly, is far more credible than a polished model with no operational history behind it.

What does an investor-ready FP&A model actually look like?

It looks like a model that tells the financial story of the business clearly, with every assumption visible and every projection traceable back to a commercial or operational driver.

The mechanics are important. Separate tabs for inputs, calculations, and outputs. A dedicated assumptions log. Colour-coded inputs so any reviewer can see exactly what is hardcoded versus what is formula-driven. Three scenarios clearly labelled and built from distinct assumption sets.

But the quality that matters most is not structural. It is whether the model reflects genuine understanding of the business. A technically perfect model built on weak commercial assumptions will not survive due diligence. A less polished model built on well-understood, well-documented assumptions will.

Do investors expect me to have a CFO or FP&A lead before raising?

Not necessarily, but they expect the capability to exist in some form.

For seed or early Series A raises, a founder who has built a credible model and can defend it in depth is often enough. What investors are assessing is not the org chart. It is whether someone in the business genuinely owns the financial planning function and understands it deeply.

For larger raises, or for businesses with complex revenue models or significant operational scale, having a dedicated FP&A lead or a fractional CFO covering the financial planning and analysis function adds significant credibility.

If you are preparing for a meaningful raise and the FP&A function is a gap, bringing in external support before the process starts is worth serious consideration. See how Powdr can help.

What happens if my actuals are behind forecast when I am in a fundraising process?

It happens. And how you handle it matters far more than the miss itself.

Investors expect businesses to miss forecasts sometimes. What they do not expect, and do not forgive easily, is a founder who does not understand why the miss happened, cannot explain the variance clearly, and has not updated the forward projection to reflect what the actuals are telling them.

A strong FP&A process means that when actuals diverge from forecast, the explanation is ready, the re-projection is updated, and the decisions that have been or need to be made in response are clear. That level of financial fluency, demonstrated in the middle of a difficult trading period, can actually strengthen investor confidence rather than erode it.

The worst position to be in during a fundraising process is not underperformance. It is underperformance combined with a finance function that cannot explain it.
