The Influence Equation is a free 1-page worksheet that helps you pinpoint why your message isn’t landing and fix it fast. Use it to strengthen your Credibility (trust), Connection (safety + alignment), and Relevance (why this matters now) so you can influence customers, sales, product, marketing, and stakeholders without relying on authority. Fill it out in 5 minutes before a meeting, a tough conversation, or an executive update.&nbsp;

Influence Worksheet

You don’t need more “executive presence” advice. You need a practical playbook for getting heard in messy deals, cross-functional debates, and leadership decisions—without authority. This one-page syllabus shows the exact 4-week path I teach: Credibility × Connection × Relevance, hard conversation setups, executive-ready technical risk language, and a 30-day influence plan you can run on a real initiative.

David Fung, Leadership Coach

Leadership coach for SE & tech leaders, Prev. Salesforce SE Sr Director

Sales Engineers live in the mess between customer reality, sales pressure, and product constraints. You see risks and better options before anyone else, yet in deal discussions your input often lands as noise. You receive vague feedback like “be more strategic” without a playbook, and left wondering what "secrets" there might be for influencing your peers.Generic leadership training does not help. Leadership books and generic communication training don’t teach you what to say in a live deal review, how to mitigate a risky sales promise, or how to fight for a feature that keeps getting bumped. It feels disconnected from the pressure of real quarters.This course matters because it starts in your world. I don’t use hypotheticals, I help you work on a live deal or initiative you own right now. You get a simple framework to diagnose why stakeholders ignore you, plus concrete scripts, written communication rewrites, and a reusable 30-day influence plan. The goal isn't to change your personality. It is to operationalize your expertise, transforming you into the trusted strategic operator leadership relies on for big decisions.
