You’ve spent weeks perfecting your pitch deck. The slides are tight, the story is compelling, and your TAM slide looks like it was carved by angels. But here’s something a lot of first-time founders don’t realise until they’re sitting across from a partner at a VC firm: the deck gets you in the room. The financials decide whether you leave with a term sheet.

VCs are professional pattern matchers. They’ve seen hundreds of decks, most of them polished. What separates the funded from the “we’ll circle back” is what sits underneath the narrative – the actual numbers, the assumptions behind them, and what those numbers say about how well you understand your own business. So what are they actually looking at?

Unit Economics That Hold Up

The first thing any serious investor is going to stress-test is your unit economics. Specifically, your Customer Acquisition Cost (CAC) and your Lifetime Value (LTV). They want to see an LTV:CAC ratio that makes commercial sense – typically 3:1 or better for SaaS businesses – and they want to understand how long it takes you to recover the cost of acquiring a customer.

If your payback period is 24 months and you’re pre-Series A, that’s a conversation you need to be ready for. If you can’t explain your unit economics clearly and confidently, that’s a red flag – not because the numbers are necessarily bad, but because it signals you may not have a firm grip on the levers that drive your business.

Burn Rate and Runway

VCs are acutely aware of timing. They need to know how long your current cash will last and how much of their capital you’ll need before you reach the next meaningful milestone. They’re not just looking at your monthly burn figure – they’re assessing whether your burn is proportionate to your growth, and whether you’re spending money on the right things.

A startup burning £80,000 a month with strong month-on-month revenue growth tells a very different story to one burning the same amount with flat metrics. Runway isn’t just a number – it’s context.

Revenue Quality and Predictability

Not all revenue is created equal. VCs place a premium on recurring revenue – MRR or ARR – because it’s predictable and scalable. They’ll look at your churn rate, your net revenue retention, and whether your best customers are staying, spending more, and referring others.

High gross churn is one of the fastest ways to lose investor confidence. If you’re adding customers through the front door but losing them just as quickly through the back, your growth story falls apart under scrutiny.

Historical Accuracy and Clean Books

Here’s one that catches a surprising number of founders off guard: your historical financials need to be accurate, reconciled and easy to understand. Messy books, inconsistencies between your management accounts and your bank statements, or revenue recognition that doesn’t follow a consistent methodology are all immediate concerns.

Investors will conduct financial due diligence. If what they find in your data room doesn’t match what you’ve been presenting, the deal can unravel quickly – and the trust damage is very hard to repair.

A Financial Model That Tells the Right Story

Your financial model isn’t just a forecast – it’s a demonstration of how well you understand your business. Investors want to see assumptions that are clearly documented, sensitivity analyses that show you’ve thought about downside scenarios, and projections that are ambitious but defensible.

The classic mistake is building a model that goes straight to hockey-stick growth with no explanation of how you get there. VCs will push on every assumption. If your revenue doubles in Month 7, they’ll want to know exactly why – and “because we’ll have more customers” isn’t an answer.

The founders who get funded aren’t necessarily the ones with the best numbers. They’re the ones who know their numbers cold, can speak to them confidently, and have built financial foundations that stand up to serious scrutiny.
