How Miratech scaled 35x in seven years by owning a niche

Executive overview

Most companies chase broad markets and stay small. Miratech picked one narrow niche — emissions control for backup diesel engines in data centers — and followed it globally.

By committing to a hundred-percent solution for one segment before that segment exploded, they moved from 43 employees in 3 countries to 1,200+ across 60 countries in seven years.

The core insight: pick a niche that's growing fast, become the best in the world at it, then follow your customer everywhere they go.

Choosing the niche

• In 2017, CEO David Zenthoefer attended a Scaling Up workshop and hired a coach on the spot
• The company was already in industrial engine exhaust — gas compression, oil and gas, power generation
• They narrowed further: backup diesel power between 1–3 megawatts for data centers
• They called the initiative Operation Big Mac and built toward a complete solution for that segment
• This decision came before the data center power density boom — the early start created a durable platform

Building the hundred-percent solution

• Developed new products, new controls and platforms, and a new service model specifically for data centers
• Didn't just sell hardware — became embedded in customer design and planning processes
• Shifted from responding to RFQs to drafting specs alongside hyperscalers
• Now work with almost every major hyperscaler, travelling to 60+ countries as clients expand

Following the niche globally

• Growth from 3 to 60+ countries was driven by going where customers went
• Physical presence in 13 countries; reps and partners beyond that
• ~74 salespeople providing daily market coverage
• Customers now come to them — inbound demand replaced outbound travel

The impact angle

• Miratech's technology removes particulates, NOx, and VOCs from engine exhaust
• In many US locations, their cleaned diesel output is measurably cleaner than grid power
• They track impact quarterly: lives improved, asthma and lung cancer risk reduced
• Portfolio company of TPG's Rise Climate Fund — an ~$8B impact fund backed by Richard Branson, Laurene Powell Jobs, Bono, and others
• One of 22 companies in the fund reporting standardised impact data
