Many successful second-time founders don't innovate into new fields. Instead, they re-apply a proven playbook to the same market, much like a gamer "speed-running" a familiar level. This leverages deep domain expertise to execute faster and more effectively, bypassing the learning curve of a new industry.

As the PE landscape became saturated with generalist firms, differentiation became crucial. Sector-specialist firms gained an edge by leveraging deep industry knowledge to win deals, often without offering the highest price. This hyper-focus, born from necessity, creates a durable competitive advantage.

Contrary to conventional wisdom, deep sector expertise can be a liability in venture capital. VC firm Felicis found that none of its 53 unicorn investments were led by an expert in that specific sector. Experts can be anchored to orthodox thinking, while generalists are better able to recognize and back disruptive, first-principles approaches.

The days of the successful private equity generalist are over. Limited Partners (LPs) now demand deep, specific expertise. A firm claiming to specialize in multiple, disparate sectors is seen as lacking true differentiation and focus—a strategy that may have worked a decade ago but fails in today's competitive market.

Resist the common trend of chasing popular deals. Instead, invest years in deeply understanding a specific, narrow sector. This specialized expertise allows you to make smarter investment decisions, add unique value to companies, and potentially secure better deal pricing when opportunities eventually arise.

Contrary to hiring functional specialists, the firm's value creation team consists of generalists with strong business acumen. Since their strategy cuts across industries, they believe generalists are better equipped to partner with management, handle complex carve-outs, and serve as interim leaders—skills that are industry-agnostic.

In private equity, capital is the ultimate commodity. The most effective way to differentiate is through deep, singular industry specialization. This expertise generates inbound deal flow, allows for unique value-add post-acquisition, and creates a memorable brand that resonates with sellers.

In venture capital, mid-sized generalist funds struggle to compete. They lack the scale and network of large generalists and the deep expertise of small specialists. This 'death of the middle' makes it difficult for them to win the best, most competitive deals against firms that can offer either breadth or depth.

The best investment opportunities aren't always in glamorous, crowded sectors like tech or healthcare. True competitive advantage comes from identifying and mastering industries with "short lines"—areas with less capital and fewer specialists, such as Main Street franchise businesses.
