The system behind the results

The JM Influence System®

Turning Businesses into Killers

Most marketing underperforms because it focuses too heavily on traffic, design or campaign activity — without understanding how buyers actually make decisions.

The JM Influence System® was created to identify the friction points that stop people from taking action.

It combines performance marketing, UX, conversion strategy and behavioural psychology to improve how prospects experience your ads, landing pages, website and offer.

Rather than guessing what needs fixing, the system shows where spend is being wasted, where buyers are losing confidence and what should be improved first.

Buyer
Psychology

Understand the questions, doubts and motivations driving purchase decisions.

Conversion
Friction

Identify what is stopping visitors from becoming enquiries, leads or customers.

Commercial
Performance

Prioritise changes that improve ROI, lead quality and revenue outcomes.

The founders

Built By Performance,
UX & Psychology Specialists

The JM Influence System® was developed by Joshua Strawczynski and Martyn Miller after years of seeing businesses waste money on marketing that looked good, generated traffic, but failed to convert.

Josh brings deep experience in performance marketing, search, paid acquisition and marketing psychology, including previous experience working with Google. His focus is identifying wasted spend, poor audience intent and the commercial levers that improve acquisition performance.

Martyn brings over 20 years of UX, product design and conversion experience, having worked across global brands including Disney, H&M, United Nations, Gordon Ramsay, Amazon, PayPal, Lego, HSBC and Vodafone. His focus is reducing friction, improving user journeys and designing digital experiences that influence action.

Together, they created a system that connects advertising, buyer psychology, UX and conversion into one practical framework for improving performance.

The science of buyer decision-making

Designed Around How People Decide, Trust And Take Action

People rarely convert because a page looks attractive. They convert when the message feels relevant, the offer feels valuable, the risk feels low and the next step feels clear.

That is why JM looks beyond surface-level design and campaign metrics. We analyse how buyers evaluate trust, compare options, process objections and decide whether to continue or leave.

This is where the JM Influence System® becomes powerful. It gives your team or agency a practical framework for improving performance based on how people actually think and behave online.

Key Principles

  • Reduce Uncertainty

    Answer the questions prospects need resolved before they feel ready to act.

  • Clarify Value

    Make the offer easier to understand, compare and believe.

  • Increase Trust

    Strengthen credibility, proof, authority and confidence throughout the journey.

  • Improve Momentum

    Remove unnecessary friction between the first click and the final enquiry or purchase.
