How The Best Companies Defend Against Mediocrity And Rot

In this episode of the Main Function Garry sits down with Eric Ries, author of "The Lean Startup", about his new book, "Incorruptible: Why Good Companies Go Bad And How Great Companies Stay Great". Ries breaks down why shareholder primacy often leads to company and product degradation, how founders can lose control of the companies they build, and what legal structures and governance models can protect a company's core mission from outside threats.

WHAT IT’S REALLY ABOUT

How mission-controlled governance prevents founder ousters and value-destroying corporate rot

  1. Ries argues that modern “shareholder primacy” governance pushes companies toward short-term extraction, eroding trust, mission, and ultimately long-term value.
  2. He frames success as increasing vulnerability: the more valuable a company becomes, the more it becomes a target for takeover, coercion, or founder removal under “best practice” governance norms.
  3. Through case studies (Twilio/Jeff Lawson, Sol Price/FedMart→Costco, Novo Nordisk), he claims common governance best practices often destroy shareholder value rather than protect it.
  4. He recommends shifting from founder-controlled or investor-controlled models to “mission-controlled” structures where the mission has sovereignty via charters, boards, and external trustees.
  5. He highlights practical early-stage steps—especially converting to a Delaware Public Benefit Corporation (PBC) and designing boards/investor relationships to create long-term mission alignment.

IDEAS WORTH REMEMBERING

5 ideas

Success makes a company a bigger governance target, not safer.

Ries argues that once a company becomes valuable, the incentives to seize control (via boards, investors, markets, or legal norms) increase, so founders need defenses before they’re “successful enough” to be attacked.

“Best practices” can be value-destroying when they optimize for short-term financial extraction.

He cites repeated patterns where firing mission-guarding founders or adopting governance ratings’ ideals leads to loss of innovation, declining trust, and weaker long-term performance (e.g., Polaroid after Edwin Land, Kroger vs. Costco).

Dual-class shares help, but they are not a durable plan by themselves.

Sunsets can end founder control quickly (Twilio), and even without sunsets, control can be undermined by financing leverage, market panics, or eventual founder death—so a backup governance system should be pre-designed.

Mission-controlled beats founder-controlled: the mission needs formal sovereignty.

Ries argues founders shouldn’t have to be “human shields” forever; instead, structures like foundations or trusts can protect purpose across leadership transitions and external pressure.

Becoming a Delaware PBC is a high-leverage, early-stage move.

He calls PBC conversion a simple filing that restores “purposeful incorporation,” giving boards legal cover to prioritize mission alongside (not solely) shareholder value—especially easy before priced equity rounds.

If you don't get the governance of your startup right, no other decision you make in the long term is gonna matter because you're not gonna be there to be the one making it.

Eric Ries

Shareholder value is like the exhaust that comes out of the engine. When you take the exhaust pipe and voot, put it in the intake and make that your explicit goal, now you don't stand for anything anymore.

If you don't take much away from this, ethos plus integrity equals incorruptible.
