Introducing: RT Williams, Founder & Energy Engineer, Pathline Foundry
Describe the business/organization you work for:
Pathline Foundry is an independent energy consulting and software firm in Meridian, Idaho. I run the gamut from benchmarking and energy audits to custom software for energy strategy, management, and optimization. It's a niche offering that's widely applicable across many industries. One engineer, start to finish. See where your energy is going, so you can make a smarter decision about where it goes next.
What inspired you to start your own business, or why did you decide to work for this specific organization?
I want to be the person who stays and partners with those who need it most. I've been doing energy engineering since 2017, and I've kept seeing the same pattern. A building gets an audit report, the report goes on a shelf, and nothing changes. Pathline Foundry grew out of that pattern, and I build software for the same reason: the findings need somewhere to live once the engagement is over, or they end up back on the shelf. Energy gets treated as a fixed cost, a line on the bill you can't do anything about. It isn't. There's real money sitting in waste and inefficiency, and most of the people who could act on it have no spare bandwidth and limited technical staff. I wanted to make that easy to see and easy to act on.
What sets this business apart from others in the industry?
There's no sales team and no handoff to a junior analyst. You talk to the person doing the engineering, and that same person is still there when it comes time to implement. I build the software side myself too, so the analysis, the modeling, and the tools a client ends up using all come from one place. Where it fits, I take a share of the savings instead of a flat fee, so the work is built to pay for itself. I'm a PhD engineer and a Certified Energy Manager. I write the work so a decision-maker can understand it and an engineer can act on it.
What challenges have you faced as a business owner or employee, and how did you overcome them?
Starting a business in a state where nobody knows you is a slow problem, and there's no clever fix for it. My family and I moved here in 2025, and I spent a lot of that first year in rooms where I knew one person, or none. What surprised me is that it made the actual work better. I used to lead with what I found in a building. Now I ask what somebody is trying to decide first, because a room full of strangers teaches you quickly that nobody cares what you know until they know why it matters to them. That turns out to be most of the job. Idaho has been more welcoming than I expected. Almost everything I've built here started with someone making an introduction, and I look forward to growing my work to support the community that made room for me.
What advice would you give to someone looking to join your industry?
Go into the buildings. You can learn modeling and software anywhere, but you can't learn how a facility actually runs from a spreadsheet. Spend time with the people who operate it. They'll tell you things no data set contains, and more often than not, they already know where the waste is.
