Our story

Why I built the KMT Stack.

Keystone Marketing Technology was founded in 2017 as a marketing technology consultancy. Since then we’ve worked with organisations across very different industries: higher education, edtech, and small and mid-sized businesses.

However different their business models, they nearly all had the same problem. A collection of platforms, each bought for a different job, that didn’t talk to one another. Data that wasn’t connected, or wasn’t right. And no one on the team with the time or the technical skills to use the platforms fully, let alone connect them. The result was a great deal of money and time spent, and very little of what had been promised.

As a consultant, my job was to understand each business and simplify its marketing technology into a system that gave owners and marketers the insight they were looking for. Over time I began using proven open-source platforms for each role in the stack, and then building templates for the way I connected them. Eventually, those templates were the most valuable thing I was delivering.

So the KMT Stack became our main offering, in place of consulting. Every launch requires three months of guided operation, because the value comes from using a platform, not simply owning one. Your team and ours set up the systems and learn them together, across the whole stack, so you see a return on the work early.

Then AI made the next step possible: an assistant that works across the entire KMT Stack for each client. Grep gives a small or mid-sized company the kind of knowledge and expertise that usually comes with a six-figure marketing technologist. Your team asks in plain English, and Grep turns the request into drafts of reports, emails, segments and more.

In effect, the KMT Stack is a set of connected platforms that an AI assistant can understand and work in, alongside your marketers. Most companies never get to a unified platform, let alone one organised well enough for AI to make sense of it. In my experience, the KMT Stack gets business owners there in weeks instead of years.

I’d love to hear what you’re working toward: where your marketing is today, where you want it to be, and what’s standing in the way. If the KMT Stack can get you there faster and for less, I’ll show you how. If it can’t, I’ll tell you that too. Either way, I look forward to the conversation.
