To ensure robust decision-making, Eclipse requires that if a partner feels strongly against a potential investment, they must join the deal team alongside the champions. This forces a direct confrontation of the risks and ensures that by the time an investment is made, all major concerns have been addressed.

Architecture giant Gensler implements a co-leadership model not just at the CEO level but throughout the firm. This structure thrives by pairing leaders with complementary skills ("aces and spaces") and is built on a foundation of deep trust, allowing partners to defer to one another's judgment in disagreements.

To improve decision-making, BlackRock's investment committee, guided by a behavioral scientist, uses autonomous voting to prevent peer pressure. It also mandates a non-voting "challenger" to play devil's advocate and champion a pre-mortem perspective, ensuring dissent is valued.

The Artemis co-founders maintain high velocity by minimizing disagreements. When they have differing opinions, the person who has thought less deeply about the specific issue defers to the one with more context. This is built on a foundation of mutual trust and recognizing most decisions are reversible.

Benchmark's unconventional structure, where all partners have equal equity and power, aligns incentives for collaboration. Instead of the 'sharp elbow' culture of hierarchical firms, this model ensures senior partners are motivated to mentor and support junior members, as everyone shares equally in their success.

To foster contrarian thinking and prevent groupthink, Lux Capital allows each investment partner one "silver bullet" per fund. This enables a partner with deep conviction to make an investment even without team consensus, mitigating the risk of missing a brilliant, non-obvious opportunity.

Managing VCs is harder than managing corporate execs. VCs are high-IQ, disagreeable idea generators who dislike rules. The burden is on leadership to design an organization that minimizes conflict, as VCs can easily 'wreck each other's businesses' through competing investments, making interpersonal issues far more destructive.

Lux Capital's founding success is attributed to the yin-yang dynamic between its co-founders: one an optimist who invents the "airplane" by seeing the best in outcomes, the other a cynic who invents the "parachute" by mitigating risk.

A strong partnership thrives on different viewpoints, not a leader and a follower. A partner who simply echoes your ideas prevents growth and leaves you vulnerable to your own blind spots. This constructive friction is essential for making robust decisions.
