Part One: 12–18 Months Before Private Equity – What SME Founders Should Start Addressing Now

Founder Guide to Prepare for Due Diligence

July 23, 2026

Series Introduction

Preparing a business for private equity investment rarely starts when founders appoint advisers or begin speaking to investors.

For UK SMEs, the strongest outcomes are usually built 12–18 months before a formal process begins. In reality, most founders don’t wake up one morning and decide to sell. The decision builds slowly, potentially off the back of an unexpected approach from a buyer, a comment at an industry dinner, or just the realisation that the business would benefit from a strategic partner to get to the next level.

The challenge is that the changes that matter most take time. Strengthening your team, improving systems and reporting, and building a more resilient business don’t happen overnight. Meaningful change takes time.

The businesses that secure the strongest valuations and smoothest transaction processes are usually those that started focusing on these areas 12-18 months before a deal was ever on the table.

Due diligence is designed to validate historical performance while assessing whether the business has the leadership, systems, controls and market position required to deliver sustainable future growth.

Investors may ask for information in a different way than the business currently uses it. The goal is not simply to verify past performance, but to understand the drivers of future growth, profitability and value creation.

At Key Capital Partners, we’ve worked with hundreds of founder-led businesses. The strongest businesses can demonstrate both:

  • Credible historical performance
  • The foundations for sustainable future growth

This two-part series focuses on the areas that matter most;

Part 1

  • Strengthening management capability
  • Know your market
  • Understand your right to win 

Part 2

  • Strengthen Financial Reporting
  • Improving operational scalability

 

Part 1 – Get Investment Ready

 

1. Strengthen the team around you

One of the questions investors will naturally ask is:

What happens if the founder or CEO steps away from the day-to-day business for a period of time?

This isn’t about making the founder less important. In most successful SMEs, the founder remains a critical part of the business. Instead, investors want to see that knowledge, relationships and decision-making are shared across a capable leadership team.

A business is often stronger, more resilient and better positioned for growth when it can operate effectively without relying on one individual for every major decision.

Ultimately, investors aren’t just assessing what the business has achieved so far. They’re assessing whether it has the people, structure and leadership capacity to continue growing in a sustainable way.

 

Focus areas:

  • Strengthen second-tier leadership. Build a credible team around you where gaps exist (commercial, operational, financial). These are the people who can step up when you’re not around – and potentially even form your succession plan.
  • Delegate operational ownership and decisions. If every pricing decision or key customer/supplier relationship still runs through you, start giving responsibility to the trusted team you’ve built.
  • Create accountability across departments. Give department heads genuine ownership of their numbers and outcomes, not just tasks to execute, but targets they’re answerable for. This is what lets investors see a business run by a team, not a founder issuing instructions.
  • Introduce KPI ownership. Assign clear, individual ownership of the metrics that matter e.g. sales pipeline, gross margin, customer churn, whatever’s core to your business, so that performance is tracked and owned at the right level, not just monitored by you at the top.
  • Improve management reporting cadence. Move from ad hoc updates to a regular rhythm (weekly or monthly) so the business runs on consistent, structured information rather than founder instinct. This builds the reporting discipline investors expect to see post deal, and in due diligence, and ties directly into the finance point above.

Key Capital Example – Lowton Infrastructure Group

At Lowton Infrastructure Group, a leading provider of end-to-end managed logistics services backed by Key Capital Partners, strengthening the management structure and managing founder succession formed part of the business’s broader growth strategy from day one.

The business built out leadership capability early, bringing in senior operational and finance hires to support the next phase of scalable growth. Talent was developed and promoted from within wherever possible, giving the team genuine ownership of the business’s direction. This meant the founders were able to step back at the right time for them, with FD Emily Vernon stepping into the CEO role. https://www.keycapitalpartners.co.uk/our-investments/commhoist/

2.  Know Your Market & Your Proposition

Private equity investors are attracted to market opportunities. Attractive market characteristics vary. They include scale, fragmentation, and regulatory tailwinds to name a few.

It is imperative that you know your own market – many founders know their customers inside out but find it surprisingly difficult to clearly define the market they’re operating in and the opportunity ahead.

The second part of the equation is clarity of proposition. The best founders have complete clarity on how their business has achieved success. For small businesses it is often a combination of service and price. Price alone may only take you so far. Dynamic SMEs demonstrate an ability to punch above their weight, winning blue-chip clients by delivering a great service. You must be able to demonstrate how you deliver this and how it is scalable.

Market size –Focus areas:

  • Market size. It’s important to build your understanding of how large your addressable market is as a small market can put a ceiling on where the business can grow to.
  • Market share. Knowing what your market share is in your market not only demonstrates competitive strength but also your awareness of your position.
  • Regulatory environment. Understand and be able to articulate how the regulatory environment your business operates in increases barriers to entry. For some of our key sectors we invest in, such as Fire & Safety or Healthcare, increasing regulatory complexity can create highly attractive market dynamics.
  • Political landscape. Be aware of how the current political landscape may impact your business and market and show that you have considered how any changes favorably or adversely affect the market.
  • Market opportunity. Now with all of the above, understand where the opportunities in your market will come from and how they will help you deliver the growth you are forecasting.

You don’t need perfect market data, but you do need a clear view of where the business sits today and where the growth is going to come from.

Now you know your market and can demonstrate that to a potential investor, how do you plan to grow at a quicker pace than the market is growing at, or take market share from a competitor. What is your right to win, and how do you differentiate yourself against your competition?

Proposition – Focus areas:

  • Price or service offering: The most obvious but sometimes most overlooked as a differentiator. Know where your pricing benchmarks vs the market and how its services differ from its competitors.
  • Technical capability: Proprietary systems, processes, or delivery methods that competitors can’t easily replicate are a core part of your growth story. If your technical capabilities are real, then this may be how you win in a competitive market.
  • Embedded customer relationships: Long-standing, deeply integrated customer relationships, where your business is woven into how the customer operates, not just a supplier they could swap out, are a powerful sign that you are doing something right and demonstrates stickiness and recurring revenue. Long-term contracts and/or strong retention metrics strengthen your proposition and the valuation you can command.
  • Brand reputation and market credibility: A strong reputation with customers, suppliers, or within the industry can be a genuine commercial asset, accelerating new business wins and supporting a more attractive investment proposition. Awards, accreditations, or third-party recognition can help evidence this.
  • Diversified revenue base: Revenue spread across multiple customers, sectors, or geographies reduces concentration risk and signals a more resilient, scalable business. Heavy concentration on a small number of clients is a risk to be aware of that investors will probe. Be ready to show investors how this base has been built deliberately, not by accident.
  • Culture: A softer area to focus on, but an equally important one, is culture. If your business operates in a sector known for high attrition rates and you can demonstrate low staff churn, and that this enables you to attract the best talent, then promote it.

Ultimately, investors are trying to answer two simple questions: Is there a large enough opportunity? And why is this business able to exploit that opportunity? The clearer your answer, the easier it becomes for others to believe in the growth story.

You don’t necessarily need the final investment thesis, that’s something we, at Key Capital Partners can support with through a partnership. However, a clear, evidence-backed view of your market position means you’re not starting from zero, and it helps you prioritise which operational fixes matter most.
