The PLUM Catalyst: Founded on Purpose, Built to Connect
Founded in 2019 by Tammy Meehan Russell, The PLUM Catalyst was born from a simple—yet powerful—idea: mobility should serve everyone.
After years working across the industry, Tammy saw something missing, a true connector between technology innovators, government leaders, and the people they aim to serve. PLUM was created to fill that gap, bridging vision and execution to make new mobility solutions not only advanced, but also human-centered and accessible.
Our team brings that same mindset to every project. We’re passionate problem-solvers who “speak the tech” and turn innovation into practical, people-centered solutions. With expertise in strategic planning, future-proofing, and funding success, we help partners design systems that move people, improve accessibility, and grow tomorrow’s workforce.
As a woman-owned, forward-thinking consultancy, The PLUM Catalyst helps partners across the country design strategies that make transportation smarter, safer, and more connected.

The Method Behind the PLUM Movement
We believe innovation happens when people collaborate with purpose. That’s why our work blends strategy and creativity — connecting research, technology, and real-world needs.
From advising and funding strategies to education and workforce development, we bring clarity to complexity and momentum to every project.
We call it our G.R.O.W. Process™ — Get Smart, Get Out, Get Growing.
Created by our founder, Tammy Meehan Russell, this approach is the foundation of everything we do — because progress shouldn’t stand still.
