Building a Second Growth Engine: Here’s a Complete Guide

How do enterprises with these characteristics overcome the bureaucratic systems that cripple most large corporations? They don’t have to. Instead, they establish independent second-engine units. For example, Bradesco Bank’s digital initiative Next operates as a separate entity—with its own forward-looking technology, target customer segments, culture, brand, and operating model. Ørsted treats each of its wind farms as an independent unit, granting site managers the freedom to shape local culture and strategy—creating a ‘mini-founder’ experience. Jio was spun off from Reliance and granted a capital structure enabling external investors to purchase its shares, while still leveraging corporate assets to accelerate growth. Leveraging the Scale and Assets of the First Engine It’s easy to focus on the disadvantages large, bureaucratic enterprises face when launching new businesses—but incumbent companies also possess advantages, primarily the ability to avoid starting from scratch. For instance, Ecolab successfully built a second engine in water purification by leveraging the capabilities, channels, sales force, and customer base of its first engine. Founded in 1923 by a salesman who noticed stains on a hotel carpet and developed a cleaning solution, Ecolab grew into a market-leading provider of industrial cleaning products and services—more than twice the size of its nearest competitor. Yet, when Ecolab’s market growth began slowing a decade ago, its leadership sought new opportunities—and identified its customers’ greatest unmet need: reliable access to clean water. The company foresaw that the water purification market would demand highly advanced technologies and expand rapidly—exhibiting clear second-engine potential. In 2011, Ecolab entered this space decisively by acquiring Nalco, the industry leader in industrial water treatment. To fund over a dozen acquisitions and equity investments in water purification technology firms, Ecolab divested non-core assets in chemicals and energy. It also leveraged its cleaning-focused sales force and antimicrobial and purification technologies to cross-sell water treatment products and services to its core customers. Since 2010, Ecolab’s revenue has surged from $6.8 billion to $11.8 billion; its enterprise value has quintupled; and its stock market capitalization has soared by 465%—outperforming the broader market by over 50%. Sharing capabilities, customer access, or distribution systems between a mature first engine and an emerging second engine does not happen naturally or automatically. Inevitable conflicts and trade-offs arise during decision-making. The key is to anticipate some of these tensions early in the process—and proactively establish agreements to mitigate them. Moreover, regularly convening standing cross-functional leadership meetings—attended by leaders of all business units and the CEO—is critical to resolving conflicts, swiftly removing bottlenecks, and identifying further synergies. The Combined Power of All Four Elements Each success factor amplifies and reinforces the others. The greater the potential of the market—and its profit pool (Element One)—the more vital it becomes to leverage existing core assets (Element Four) to seize share ahead of competitors.

Special Issue #6 | Thermal Management Supply Chain: Four Billion-Dollar Acquisitions in One Year—What Are the Giants Buying?

Data Sources: Dell’Oro, GMI, company announcements (Eaton / Ecolab / Trane / Vertiv / Modine), and publicly available industry reports. The previous article on the power supply chain ended with a teaser: 800V power delivery and liquid-cooling piping are now being integrated within the same server rack—electricity and heat converging. This article explores the thermal half of that convergence: the thermal management supply chain. First, consider this timeline—remarkably dense even by AI hardware industry standards. Eaton acquired Boyd, a thermal management leader, for $9.5 billion—securing approximately $1.5 billion in liquid-cooling revenue. Water treatment giant Ecolab acquired CoolIT, a top-tier liquid-cooling firm, for $4.75 billion in March 2026. HVAC leader Trane acquired LiquidStack, a company specializing in immersion cooling. Vertiv acquired Strategic Thermal Labs. Power infrastructure giants, water chemistry specialists, and HVAC leaders—all lined up within roughly one year to write multi-billion-dollar checks for liquid-cooling technologies. When industry giants choose acquisition over in-house R&D to enter a market, it signals that the window of opportunity has narrowed—even shorter than the typical internal development cycle. This article follows those acquisition checks to dissect the thermal management supply chain layer by layer: where the money flows, who’s securing strategic positions, where competition is intensifying, and where untapped business opportunities remain hidden. I. Core Thesis: Liquid Cooling Has Evolved from a Niche Product into Mainstream Infrastructure The prior article on power and thermal management explained the physics: air cooling hits its ceiling at 20–30 kW per rack, whereas AI racks now exceed 100 kW—e.g., the GB200 NVL72 reaches ~120 kW—making direct liquid contact with chips mandatory. This article adds the industrial logic: how large is this air-to-liquid transition, and how is value distributed across the chain? Market size figures: the liquid-cooling market is projected to reach ~$4.8 billion in 2025, ~$6.0 billion in 2026, and ~$27.1 billion by 2035—a compound annual growth rate of ~18%. Its fundamental value proposition can be distilled into one sentence: liquid cooling reduces cooling energy consumption by over 30% compared to conventional refrigeration—in an era where “saving electricity equals expanding capacity,” every watt saved on cooling directly translates into sellable compute power. That is the logic behind the giants’ checks. II. Industry Narrative: Ecolab’s $4.75 Billion Purchase Was Not About Hardware Among the four acquisitions, Ecolab’s acquisition of CoolIT merits special attention—because it’s most easily misunderstood. Ecolab is a global water treatment leader, primarily serving industrial clients with water chemistry solutions: corrosion inhibition, scale prevention, and water quality monitoring. Its $4.75 billion acquisition of CoolIT—a leading manufacturer of CDUs (Coolant Distribution Units) and cold plates—prompted an immediate market reaction: “A water treatment company venturing into hardware.” But the real strategic calculus lies in the business model: hardware sells once; chemicals generate recurring annual revenue. Once a liquid-cooling system is operational, coolant degrades, piping corrodes, and water quality requires continuous monitoring—creating a consumables-and-services-based recurring revenue stream. And that is precisely Ecolab’s core competency. By bundling CoolIT’s CDU hardware with its own coolant chemistry formulations and water management services, Ecolab didn’t acquire just an equipment vendor—it secured the “consumables entry point” for the entire liquid-cooling era.
