A universal marketing efficiency score. At last.

Marketing System Efficiency is a universal metric - but the decision it informs depends entirely on who is asking. For a PE deal team, it quantifies latent growth before capital is committed. For a CMO, it shows where the structural levers are. For an agency, it changes the nature of every client conversation.

OUR CUSTOMERS

Four audiences, one metric.

WHO USES MSE DIAGNOSTICS

The MSE diagnostic was built for Private Equity — but the question it answers is relevant to anyone who runs marketing and wants to know how efficiently it is working.

  • For the first time, marketing is a number.

    PE firms spend billions acquiring companies where 10–30% of OPEX goes on marketing. Until now, there has been no fast, independent, rigorous way to quantify whether that spend is efficient, or what it would take to make it so.

    MSE changes that. It gives deal teams and portfolio managers an objective, data-led view of marketing efficiency at every stage of an investment, without requiring management information, internal data access, or co-operation from the target company.

    Our diagnostic was built on 40 Private Equity assignments over eight years and validated against more than 1,000 companies. The output is designed for investment committees, value creation plans and board discussions.

    It runs entirely on external signals. No management information, no internal data, no co-operation from the target. We estimate that on average 30% of global marketing spend is structurally inefficient. MSE finds it, quantifies it, and shows exactly where the value creation opportunity lies.

    • Pre-deal MSE screening without internal data access

    • Post-acquisition value creation planning and 100-day roadmaps

    • Hold period portfolio benchmarking on a consistent scale

    • Cross-portfolio MSE comparison - identify where to focus support

    • Marketing risk categorisation before IC presentation

    • Board-ready MSE reporting, monthly or quarterly

  • Walk in knowing their MSE score before they do.

    The agency that can show a prospect their Marketing Structural Efficiency score - before a brief has been written, before the pitch has started - changes the nature of the conversation entirely.

    MSE gives agencies and consultancies an independent, data-led starting point for any client engagement. Run a diagnostic on a prospect before the pitch. Walk in with their score, their competitive position, and a clear view of where their marketing efficiency is leaking.

    For retained clients, MSE provides ongoing monitoring, identifying structural weaknesses before the client raises them and shifting the agency relationship from reactive to strategic.

    As marketing services are democratised and move towards zero cost, the agencies that survive are those that sell intelligence, not just execution. MSE is that intelligence.

    • MSE diagnostics as a new business development tool

    • Ongoing client MSE health monitoring

    • Independent evidence base for strategic recommendations

    • Competitive MSE benchmarking for proposals and pitches

    • Sector-wide MSE intelligence for thought leadership

  • The marketing metric that’s always been missing from your board pack.

    MSE gives marketing leaders what finance has always had - a metric that is objective, comparable and trackable over time. Not a sentiment score or a survey. A structural efficiency rating, benchmarked against competitors.

    Marketing has historically been difficult to defend in the boardroom because it has lacked a universal, independent metric. MSE is that metric. It scores marketing efficiency across 27 levers in three domains - product, brand and digital - and benchmarks the result against competitors in your category.

    For international brand portfolios, MSE is particularly powerful. The same framework applied to your brand in Romania, Peru, Germany and the UK - on a consistent scale, at the same time, without internal resource burden.

    • MSE baseline across 27 levers - objective and externally benchmarked

    • Cross-market MSE comparison for international brand portfolios

    • Competitor MSE analysis by category and territory

    • Board-level marketing metric, tracked quarterly

    • Prioritised growth plan for CMO and board alignment

  • Bring MSE to your clients under your brand.

SERVICES

Service 01
Growth planning from MSE findings
Where the MSE diagnostic identifies clear growth opportunities, Bridge F61 develops a structured growth plan that translates those findings into a prioritised, actionable programme.
Particularly relevant for PE portfolio companies post-acquisition, where management teams need a clear, board-endorsed marketing roadmap as part of the first 100 days.
Service 02
Remedial fix planning
Where MSE reveals specific structural weaknesses, Bridge F61 develops detailed remedial plans for each area — scoped, prioritised and ready for execution by internal teams or agencies.
Plans are delivered in a format that can be handed directly to an internal marketing team or incumbent agency without additional briefing.
Service 03
Marketing team workshops
Bridge F61 runs structured workshops with client marketing teams to interpret MSE findings, build shared understanding of the efficiency gaps, and align on the actions needed to close them.
Facilitated by senior Bridge F61 practitioners. Working sessions, not presentations.
Service 04
Ongoing advisory
For customers running repeated MSE diagnostic cycles, Bridge F61 provides ongoing advisory support — reviewing progress, interpreting new data and advising on course corrections.
A light-touch, senior-level engagement rooted in the MSE data and practitioner experience.

How services work: Services are available to diagnostic customers where Bridge F61's expertise is directly applicable to the MSE findings. They are scoped individually — the starting point is always the diagnostic output, not a separate conversation.

Some of our client portfolio clients

  • A full diagnostic is typically delivered within 72 hours of briefing. For live deal situations we can discuss priority turnaround. The process requires no co-operation or information from the target company — it runs entirely on external signals.

  • Yes. The 27-lever framework applies to any business with a marketing function. Diagnostics have been run across consumer, B2B, SaaS, industrial and professional services businesses in the UK, Europe and beyond — and in any language.

  • Because every diagnostic uses the same 27-lever framework and scoring methodology, results are directly comparable across companies, sectors and markets. Portfolio managers can rank companies by MSE, identify outliers, and track progress over time on a consistent scale.

  • Most agencies start by running a diagnostic on one or two prospects or existing clients. Once the output format is clear, many move to a standing arrangement — running MSE diagnostics on new prospects as part of their standard new business process.

  • Services are available to diagnostic customers where Bridge F61's practitioner expertise is directly applicable to the MSE findings. They are scoped individually. The starting point is always the diagnostic output — not a separate proposal.

  • Yes — white-label and co-branded licensing is available through the Bridge F61 Sales Partners programme. Designed for agencies, consultancies and intermediaries who want to embed MSE diagnostics into their own client service offering.
