The framework begins with top-down sector selection rather than opportunistic deal hunting. Investors identify industries with stable, secular growth that should persist for roughly a decade, then develop deep operating knowledge in those areas. Within those sectors, they acquire a safe, established company at a reasonable price and avoid relying on excessive debt. The acquired business becomes a protected base from which to pursue venture-like upside through better management, acquisitions, sales capacity, technology, international expansion, and other operational improvements. Downside protection and business building work together: a favorable industry reduces the chance that external conditions destroy the company, while active ownership creates growth that does not depend on falling interest rates or rising valuation multiples.
Origin
Klinsky developed the approach from lessons at Forstmann Little, particularly the failure of weak companies during recessions and the success of building General Instrument. He made defensive growth and business building the founding principles of New Mountain Capital.
Core principles
- 01Choose industries with durable secular growth.
- 02Protect the downside before pursuing upside.
- 03Buy stable businesses with unrealized growth potential.
- 04Create returns through operational improvement rather than leverage.
- 05Treat every acquired company as a business to preserve and build.
How to run it
- 1
Select defensive-growth sectors
Identify industries with clear, stable secular growth for approximately the next ten years. Avoid sectors whose economics can disappear because of commodities, fashion, regulation, or speculative enthusiasm.
Pro tip Look for essential products, embedded suppliers, recurring demand, and durable structural trends.
Watch out A well-managed company can still fail when its entire industry melts underneath it.
- 2
Build sector expertise
Develop enough specialist knowledge to distinguish durable leaders from superficially attractive businesses. Use that expertise across acquisitions, lending, and operational decisions.
Pro tip Concentrate on a limited number of sectors where the team can become unusually knowledgeable.
Watch out General market enthusiasm is not a substitute for understanding industry mechanics.
- 3
Acquire a safe base
Choose an established, stable business that has not yet exhausted its growth opportunities. Pay a reasonable price and structure the acquisition with enough equity to withstand adverse conditions.
Pro tip Favor businesses that already serve necessary customer needs but remain underdeveloped operationally.
Watch out Do not confuse a low valuation multiple with genuine safety.
- 4
Protect the company
Approach the acquisition with family-business responsibility rather than portfolio-level indifference. Preserve the operating base, address problems early, and avoid structures that can force failure.
Pro tip Stress-test whether the business can continue paying its obligations if conditions deteriorate.
Watch out Excessive leverage can destroy an otherwise viable company before improvements take effect.
- 5
Activate growth levers
Expand the business through acquisitions, sales-force development, technology investment, internationalization, strategic repositioning, or other company-specific improvements.
Pro tip Prioritize growth levers the previous owner lacked the resources or experience to pursue.
Watch out Do not assume that capital alone will create operational growth.
- 6
Compound operational gains
Use the enlarged company's resources and accumulated sector knowledge to strengthen both the business and future investments. Continue measuring success through durable unit growth and enterprise value creation.
Pro tip Turn lessons from each portfolio company into reusable capabilities for the next acquisition.
Watch out Do not rely on valuation expansion or falling interest rates to rescue weak operating performance.
In the wild
New Mountain acquired the business then known as JT Baker when it was going to be discontinued, renamed it Avantor, changed its management and strategy, and built it into a global leader in laboratory equipment and life-science supplies.
→ The company grew from a small acquisition into a business valued at more than $20 billion.
New Mountain backed Signify's home-based medical assessment business and expanded its capacity to send doctors and nurses into patients' homes.
→ Annual home visits increased from roughly 250,000 to 2.5 million before the planned sale to CVS.
Forstmann Little found a leading cable and satellite equipment operation buried inside a troubled conglomerate. Klinsky helped build the company through digital television, cable-modem, and on-demand technology initiatives.
→ Enterprise value rose from about $1 billion to approximately $20 billion during the 1990s.
Common mistakes
Buying cheap companies in bad industries
A low purchase multiple cannot compensate for an industry or competitive position that is structurally deteriorating.
Using leverage as the growth plan
Debt can magnify favorable market conditions, but it cannot replace unit growth and operational improvement.
Treating losses as portfolio statistics
Portfolio theory can encourage owners to tolerate avoidable failures because another investment may compensate for them. The family-business approach instead makes preserving each company an explicit responsibility.
Is it for you?
Best for
It is best for long-term owners and investors who can actively improve established companies.
Not ideal for
It is not ideal for passive traders, distressed speculation, or investors seeking returns primarily from financial engineering.

“it was really based on two principles defensive growth and business building.”

“We buy a business that's already safe and stable but hasn't figured all the ways to grow itself yet, and then we grow it in…”
