Private equity buys companies to flip them within 3-7 years.

Holding companies buy companies to sit on them for a long time, and hope it works out.

We buy good middle-market businesses, and shape them into enduringly great companies.

Kastellet is the star-shaped fortress in the heart of Copenhagen — built to protect what matters most. It has stood for over 350 years. Not because it was never tested, but because it was continuously reinforced and intentionally designed to endure.

That is what we build. Businesses that compound. Teams that grow. Value that endures.

continuous improvement

Small actions compound into insurmountable advantages. We embed a daily discipline of improving processes, raising quality, and eliminating waste in every business we own. That includes equipping your team with the tools and technology — including AI — to compete for decades, not just survive the next cycle.

Better every day. Stronger every year.

OWnership

We develop leaders from within, share equity broadly, and give every employee line of sight to how their work drives results. Ownership is not a title. It is a stake, a mindset, and a responsibility. When people own what they build, they build things that last.

Your people grow with us — not despite us.

permanence

We buy businesses with no intention of selling them. Our capital is permanent. Our time horizon is measured in decades. This is not patience for its own sake — it is the precondition for genuine investment in people, systems, and growth.

You cannot build something truly durable on a three-year clock.

We acquire good businesses that can be made great. The base case should work without heroic fixes. We are looking for durable advantages to build upon, not turnaround projects.

recurring revenue

Predictable cash flows through economic cycles. Contractual or habitual revenue streams. $3–15M EBITDA.

mission critical

Products embedded in the customer's core operations. Essential, not nice-to-have. High cost of removal. We look for businesses where technology adoption strengthens the moat rather than commoditizes it.

NICHE MARKET LEADERS

Dominant share in markets too small for large players, large enough to compound. Local champions welcome.

Pricing power

Ability to dynamically adjust prices without losing customers. High switching costs. Low product cost as a percentage of total customer spend.

STRONG PEOPLE

Capable teams already in place. We invest in your people — we don't seek to replace them.

CULTURAL FIT

Owners who genuinely care about legacy, people, and the community. Not just the highest bid or flashiest presentation.

Day 1
introductory call

A 30-minute conversation to learn about your business, your goals, and whether there's a fit worth exploring.

Day 2
mutual nda

We sign a mutual NDA protecting both sides. Your information is treated with the same care we'd want for our own.

Week 1
Basic INFORMATION EXCHANGE

We share a simple list of what we'd like to review. Revenue detail, high-level financials, team overview. We keep it focused.

Week 2
Letter of intent

Based on our review, we present a clear term sheet with valuation and structure. Simple, fair, and direct.

Weeks 3-8
Due diligence

We confirm the key things we care about in the first two weeks. The rest is confirmatory. We won't nickel-and-dime you.

Day 60
target closing date

We sign the purchase agreement and wire the funds. Then the real work begins — together, or with you cheering on from the sidelines based on your preference.

Whether you're a business owner exploring your options, a broker representing a client, or a lender evaluating a partner — we'd like to hear from you.
