Preparing for due diligence: what good looks like

James Bloor

Here's a scenario that plays out more often than you'd think. A founder gets the call - someone's interested in acquiring the business. It's the moment they've been working towards. And then, within about three weeks of due diligence, the deal falls apart. Not because the product wasn't good, or the revenue wasn't there, but because the business couldn't withstand scrutiny.

The messy cap table. The contractor who built the first version and might still technically own the IP. The financial model held together with sticky tape and optimism. None of it seemed like a problem until someone with a chequebook started asking hard questions.

Due diligence doesn't reveal problems. It reveals problems you didn't know you had.

And that's the thing most founders get wrong about this process. They think of due diligence as something you prepare for when an offer arrives - a box-ticking exercise you cram for like an exam. But in reality, the businesses that sail through due diligence are the ones that were running cleanly long before anyone came knocking. So even if you're not planning to sell anytime soon, this stuff matters. Because running a business that can withstand scrutiny isn't just about exit-readiness. It's just good practice.

What buyers actually look at

Due diligence typically covers four broad areas: technical, legal, financial, and commercial. The weighting depends on who's buying and why, but expect all four to get a proper going-over. Let's walk through what that actually means in plain terms.

  1. Technical due diligence. This is where acquirers dig into the product itself. How's the code? Is it well-structured, documented, and maintainable - or is it a heroic mess that only one developer truly understands? They'll look at your architecture, your infrastructure, your deployment processes, and your security posture. They'll want to know about tech debt and whether the platform can scale. If you've been cutting corners to ship fast (and honestly, most early-stage startups have), that's not necessarily a deal-breaker - but not knowing where the corners were cut absolutely is. Put another way: buyers expect some rough edges. They don't expect surprises.
  2. Legal due diligence. Who owns the IP? It sounds like a simple question until it isn't. If you used freelancers or an agency to build your product, do you have clear, signed agreements confirming that you own what they built? Are your employee contracts airtight on IP assignment? What about third-party code, open-source licences, or data processing agreements under GDPR? Buyers will also look at your corporate structure, shareholder agreements, and any outstanding or potential legal disputes. This is where professional legal advisers earn their fee - we're not lawyers, and we won't pretend to be - but we've seen enough deals wobble on this stuff to know it deserves attention early.
  3. Financial due diligence. Revenue is great. But buyers want to understand the quality of that revenue. Is it recurring or one-off? How concentrated is it across your customer base? What do your margins actually look like once you strip out the founder's goodwill and below-market salaries? They'll go through your accounts, your forecasts, your burn rate, and your tax affairs. And if your bookkeeping has been, shall we say, creative - or just neglected - this is where it shows.
  4. Commercial due diligence. This is the "so what?" layer. Is the market real? Is the product solving a genuine problem, or is it a solution looking for one? Buyers will assess your competitive position, your customer acquisition costs, churn rates, and pipeline. They'll talk to your customers. They'll stress-test your growth assumptions. And they'll form a view on whether the business can thrive without you - because if it can't, that changes the deal significantly.

The nasty surprises (and how to avoid them)

Most due diligence horror stories fall into a handful of categories. The IP ownership gap is a big one - especially for startups that moved fast in the early days and didn't bother with proper contracts. Unclear cap tables are another classic, particularly where verbal agreements or informal arrangements were made with co-founders or early contributors. "We'll sort the equity split out later" is a sentence that has torpedoed more acquisitions than anyone cares to admit.

Then there's the technical side. If your product is built on a codebase that nobody but the original developer can work on, that's a risk. If you don't have proper version control, automated testing, or deployment pipelines, that tells a buyer the engineering function isn't mature. And if there are known security vulnerabilities you've been meaning to get round to - well, now you know why that matters.

The businesses that sail through due diligence are the ones that were running cleanly long before anyone came knocking.

The good news? None of this is unfixable. But it's a lot easier to fix proactively than it is to scramble when a buyer's already in the room. A quick gut-check: if someone asked to look under the bonnet of your business tomorrow, would you feel confident or slightly sick? That reaction tells you everything.

Why this matters right now (even if you're not selling)

There's a tempting voice that says "we'll sort the paperwork out if someone makes an offer." And it's wrong, for a few reasons. First, because due diligence moves fast and you won't have time to untangle years of mess in a matter of weeks. Second, because the act of getting your house in order almost always surfaces things that make you a better-run business regardless - tighter contracts, cleaner finances, better-documented product decisions. And third, because buyers aren't the only people who care about this stuff. Investors do too. So do potential hires, partners, and frankly, your future self.

Building a clean, well-documented business from the start isn't about being paranoid. It's about removing friction from your future. Whatever that future looks like.

So where does Rise fit in?

We're not accountants and we're not lawyers - you'll need those, and we'll be the first to say so. But a huge chunk of what makes or breaks due diligence sits in the product and commercial space, and that's exactly where we operate. From how your product is architected and documented, to whether your tech stack is maintainable, to how your commercial model stands up to scrutiny - these are things we help founders get right from day one.

Because the best time to prepare for due diligence isn't when someone's interested. It's now.
