A permanent home for excellent businesses

Partner equity, not private equity

Your life's work deserves better than a flip.

Private Holding Company — NZ & AU

We studied 500+ companies to get this model right. The holding company model — practiced by Lifco, Addtech, and Judges Scientific across Scandinavia and the UK — has quietly built some of the best-performing industrial portfolios in the world.

We're not buyers of businesses. We're partners, operators, and long-term owners.

Why business owners choose PermaTech

Permanent ownership

We don't acquire businesses to restructure them, rebrand them, or flip them in five years. When we buy, we hold — indefinitely. Tubman Heating: 40 years intact since 2024.

Your people. Your culture. Your name.

Management stays. The team stays. The reputation you've spent decades building stays. We don't send consultants in on day one. We don't rename anything. We don't fix what isn't broken.

A fair deal — not a process

One conversation. One offer. No renegotiation during due diligence. No auction designed to extract leverage. We respect your time and your privacy, and we do what we say we'll do.

We're not buyers. We're partners.

"We're not buyers of businesses. We're partners, operators, and long-term owners."

This distinction matters. Unlike traditional private equity firms that buy, improve, and sell within 3–7 years, we acquire excellent businesses with the explicit intent to hold them forever. We bring operational expertise, we stay after the deal closes, and we measure our success by the enduring health of the business 10, 20, or 30 years from now.

We don't extract value through aggressive cost-cutting or forced exits. We build value by supporting the management teams, investing in growth, and preserving the culture and reputation you've built over decades.

We studied 500+ companies to get this model right.

The holding company model — practiced by Lifco, Addtech, Lagercrantz, Indutrade, and Judges Scientific across Scandinavia and the UK — has quietly built some of the best-performing industrial portfolios in the world. The formula is deceptively simple: buy excellent businesses, treat them well, and never sell.

We've applied that model here, in NZ and Australia, starting with the kinds of businesses we know best: industrial, commercial, skilled, essential. Businesses that don't make headlines but keep the country running.

Tubman Heating Limited — Auckland, New Zealand

Acquired 2024. Founded 1984. 45 staff. Industrial and commercial boilers and burners. Forty years of reputation, intact. The same management team. The same customers. The same standard of work. That's the PermaTech model in practice — not a transformation story. A continuation story.
