COMMERCIAL NEGOTIATION ADVISOR TO FOUNDERS & CEOS | AUTHOR
I help founders and CEOs get the deals that shape their business right.
Because who you are when you negotiate shapes the outcome.
Author of The Negotiation Playbook
Glin Bayley
I spent seventeen years as a commercial finance executive in global businesses, learning to read a deal by its numbers. What I kept seeing was that the people at the table decided more than the numbers did. How they prepared, what they believed they could ask for and what they were afraid of losing.
In 2018 I left corporate life to work on that directly. Since then I’ve spent more than five years in commercial negotiation, including as a senior negotiation consultant with The Gap Partnership, working with commercial and procurement teams across ASX-listed and global organisations.
Alongside that, I’ve coached and advised leaders through some of the biggest decisions of their careers.
Today I work with founders and CEOs on the negotiations that shape their business. I bring the commercial lens of someone who’s sat on the finance side, the negotiation expertise to help you prepare and hold your ground, and the depth to look honestly at what’s going on underneath.
My Approach
Negotiation from the Inside Out
Every negotiation has two sides.
The outer negotiation is the deal in front of you. What it’s worth, where your leverage sits, how to prepare and how to hold your position when the pressure comes on. This is grounded in my VALUE methodology, the framework at the heart of The Negotiation Playbook.
The inner negotiation is the set of agreements you’ve made with yourself about what you’re worth, what you’ll tolerate and how much you need to carry. They shape every outer negotiation, often without you seeing it. Once you can see them clearly, you get to decide which ones still serve you.
I work on both, because that’s where the result is.
WHAT CLIENTS HAVE DONE
A general manager saved $360,000 in a single negotiation after we prepared together.
A procurement leader I trained saved over $600,000 in one deal.
A CEO described “savings of millions of dollars for the business and unlocking capability in team members who had previously hit a ceiling.”
An aerospace business I advised negotiated “some of the largest and most strategically significant contracts in our company’s history.”
WORKED WITH, AND TRUSTED BY, LEADING ORGANISATIONS
Where THIS STARTED
MY FOUNDATIONS
Heart of Human (2018 to 2022)
Where the inner work began. I coached and facilitated leaders through self-leadership and identity shifts, built on my HEART framework. It’s where I learned how much of a leader’s results depend on the negotiation they have with themselves.
The Value Negotiator (2022 to 2025)
Where my negotiation methodology took shape. I worked with sales, commercial and procurement teams across ASX-listed and global organisations, and developed my VALUE methodology, which became the heart of The Negotiation Playbook (Wiley), a double category winner at the Australian Business Book Awards.
Both now live under SimplyGlin.
A BIT MORE ABOUT ME
I grew up in Birmingham, raised by a single mum who did't speak English but did everything she could to ensure I got to be university educated. At 35 I moved to Australia on my own, with no network, and built everything from there. I now live on the Sunshine Coast.
I’ve written three books, The Negotiation Playbook, Unstoppable Woman and Healing After Heartbreak. I’ve shared my work on national TV and podcasts, and I write every week on Substack at You Are Subject No.1.
