Business model and strategy
Amphenol
How it makes money
The business model is high volume, highly specialized B2B component manufacturing. Amphenol sells hundreds of thousands of connector, cable, antenna and sensor variants to thousands of customers, and no single end market dominates: in 2025, data centers and information technology accounted for 36% of sales, industrial 19%, automotive 15%, communications networks 10%, defense 9%, mobile devices 6% and commercial aeros…
Growth strategy
Amphenol's growth strategy has two parts: sell into secular demand and buy specialized suppliers. On the first, it builds high speed copper and optical interconnects for AI clusters, including the Celerity mezzanine connector family rated to 224 Gb/s PAM4 and XtremePass co-packaged copper interconnects aimed at 448G class links, plus high voltage connectors and sensors for electric vehicles, which carry more wiring a…
Competitive advantage
Amphenol's competitive advantage rests on switching costs and the cost of failure. A connector may cost a few cents, but if it fails the aircraft, satellite or server rack around it stops working, so buyers qualify suppliers rather than shop on price.
Assurant
How it makes money
Assurant sells almost nothing under its own brand. It builds protection programs that partners distribute: T-Mobile's Protection 360 device plans, extended service contracts sold by retailers, vehicle service contracts sold through auto dealers, renters insurance offered through property managers, and lender-placed homeowners insurance bought by mortgage servicers when a borrower's own policy lapses.
Growth strategy
Growth comes from three places. First, more of the device lifecycle: mobile trade-in programs Assurant runs returned a record $6.4 billion to consumers in 2025, up 42% year over year, and the company handles roughly 22 million trade-ins annually, which supplies the certified pre-owned inventory it uses to settle claims.
Competitive advantage
Assurant's advantage is physical and contractual rather than brand-led. It processes about 20 million devices a year through eight device care centers, including the Nashville Innovation and Device Care Center, which runs automated lines using robotics and AI, and it offers same-day, same-unit repairs through a network of roughly 1,150 repair and partner locations.
