Advising Owner-Managed UK Businesses on Succession & Exit Strategy
Specialist advisory support for privately held businesses typically generating £5–20m in enterprise value. Bringing buy-side experience, rigorous preparation and dedicated attention to ensure your exit is structured, positioned and executed properly.
Blackline Capital was founded by Leighton Herdson, an experienced SME transaction advisor with a background in both acquisition and sell-side advisory.Leighton works directly with founders and owner-managers considering succession, retirement or strategic exit — providing structured guidance, hands-on execution and clear commercial judgement throughout the process.
With experience on both sides of the table, Leighton brings a pragmatic, outcome-focused perspective to each engagement.From early preparation through to final negotiation, every stage is managed carefully — ensuring the business is properly positioned, buyers are credible and competitive tension is created where appropriate.
Blackline Capital works with a limited number of clients each year to provide full lifecycle advisory support.This includes preparation of financial materials, development of a compelling market narrative, targeted buyer outreach and disciplined negotiation.The objective is not simply to “list” a business for sale — but to manage a structured, controlled process designed to protect and enhance value.
Each engagement follows a structured four-stage process:1. Initial Discussion
Clarify objectives, timing and strategic considerations.2. Valuation & Preparation
Establish realistic market value and prepare professional documentation, including a Confidential Information Memorandum.3. Buyer Engagement
Discreetly approach qualified buyers, manage information flow and create competitive tension where appropriate.4. Negotiation & Completion
Provide structured guidance through offers, due diligence and final negotiations to achieve a controlled and successful outcome.
For many owner-managed businesses, the most effective exits are prepared well in advance.Beginning the process 12–24 months before a formal transaction allows time to strengthen financial presentation, address operational dependencies and consider the most appropriate buyer profile.Exploring strategic options does not commit you to a sale. It provides clarity.In some cases, that clarity confirms it is the right time to proceed. In others, it provides a structured plan for the future.
