How a 600-Person Global Supply Chain Leader Built Its Sustainability Story From Scratch
In our latest Green Tech Focus interview, Mary Kelly, Chief of Staff at Overhaul, shares how the company started its sustainability journey, why it chose the ENSO platform, and how that decision helped turn sustainability into a real business advantage.
Overhaul's Chief of Staff Mary Kelly sat down with Techies Go Green team & Donal Quinn from ENSO to unpack the company's sustainability journey.
Sustainability is no longer optional. Ask any procurement team, investor or new hire what they need to see before they commit, and ESG comes up every time. Not as a bonus but as a requirement.
The challenge is that most businesses want to take action, but they don't know where to start. They aren't sure what information they need, who should lead the work or how to show customers the progress they're making.
That's exactly where Overhaul found itself a few years ago.
Today, the Irish-founded global supply chain technology company has an embedded sustainability strategy, a published sustainability report and a live ESG platform that helps it communicate its progress with customers, investors and its team of more than 600 employees around the world.
Meet Overhaul
Overhaul isn't a small operation testing the sustainability waters. Founded in 2016 by two Irish entrepreneurs — CEO Barry Conlon (based in Austin, Texas) and COO David Broe (based in Overhaul's European HQ in Dundalk, Co. Louth) — Overhaul has grown into a global supply chain risk management company with roughly 600 team members worldwide. They give clients real-time visibility on shipments in transit and back that up with insurance services, making them a critical partner for businesses that can't afford blind spots in their supply chain.
Since its founding in 2016, Overhaul has grown into a global supply chain risk management company protecting $1.4 trillion worth of goods through its platform. Headquartered in Austin, Texas, with strong Irish roots, the company has also been recognised on the Inc. 5000 list after achieving 300%+ revenue growth. As the business expanded, sustainability became another area where it needed a clear strategy and a practical way to demonstrate progress.
The Problem: Passion Without a Framework
Mary's sustainability journey started almost by accident — a supply chain master's module at UCD that reframed how she thought about her entire career, followed by a chance connection with a graduate hire who shared the same interest. Between the two of them, they had the will to act, but not the expertise to know where to begin or how to get the rest of the business on board.
"That's a pattern we see across almost every company we work with at Techies Go Green: real appetite for change, but no map."

The Shift: What Enso's Platform Actually Changed
Once Overhaul brought in Enso, the difference wasn't just "having a strategy" — it was having a system. According to Mary, the platform gave Overhaul a structured way to:
What the Enso platform gave Overhaul
► Audit what they were already doing— most businesses, Overhaul included, are doing more good than they realise until someone helps them see it laid out
► Build and publish their sustainability report— Overhaul has now released two, with the second becoming a serious undertaking as it moved from a one-off exercise to an evolving, evidence-based story
► Communicate continuously, not annually— rather than a report that goes stale the day after it's published, the platform let Overhaul showcase live progress with customers and staff
► Answer harder, more frequent supply chain questionnaires— ESG questionnaires from partners have gone from a handful of questions eighteen months ago to well over 150 today
► Turn culture into a visible sustainability asset— from their "100k in 30 Days" step challenge to community volunteering, Overhaul now has a home to showcase the people side of their ESG story
"Sustainability at Overhaul stopped being one person's side project and became something woven into funding conversations, client pitches, employee retention, and brand identity."
Why This Matters Beyond Overhaul
Overhaul's story is a proof point, not an outlier. As Enso founder Donal Quinn explained in the interview, most businesses that come to Enso don't have a dedicated sustainability manager. What changes the outcome isn't headcount — it's having the right platform and framework to turn scattered good intentions into something structured, provable, and communicable.

An Offer Built for Members Who Are Serious About Getting ESG Right
We don't take partnerships lightly. Every partnership we bring to our community is chosen because it solves a real problem our members face. Enso solves one of the most common ones we hear: businesses that want to act on sustainability but don't know where to start, how to structure it, or how to prove it to the people asking.
Enso's platform is the same one powering Overhaul's ESG reporting, a company that just raised $105M with sustainability credentials built into the story. That tells you something about what a credible ESG foundation can do for a business.
Through our partnership with Enso, Techies Go Green members get access to a dedicated starter plan on the Enso platform, the same starting point Overhaul used to run their initial ESG audit, map their gaps, and begin building their internal green team. The starter plan is designed specifically for SMEs. It walks you through building your sustainability strategy, sets out a clear roadmap with actions and timelines, brings your team into the process through a shared platform, and gives you a branded public webpage to show real progress to customers, partners and stakeholders. No blank page. No guesswork. Just a structured path that has already worked for businesses like Overhaul.
Who this is for
Over 1,000 businesses across the UK and Ireland are part of this community. This offer exists because we believe every one of them should have access to the same proven tools that companies like Overhaul used to build their ESG story.
