About this collection

As we were getting started, I researched the best practices and non-obvious things to look for in hiring our founding team. This collection curates key content that shaped our hiring framework focused on **velocity, quality, and cultural fit**. Core insights: - **Small teams win**: Patrick Collison advocates for 2-10 people pre-PMF to maintain rapid iteration - **Barrels vs Ammunition**: Keith Rabois's framework for identifying rare, high-impact contributors who execute end-to-end - **See people clearly**: Graham Duncan emphasizes references are 5-10x more valuable than interviews—what people say vs. how they actually operate daily - **T-shaped talent**: Deep expertise in one area, competent across many—perfect for startup ambiguity - **Prevent mediocrity**: Ben Horowitz warns organizations naturally drift toward average without safeguards My favorite tactic: **the anti-pitch**. Tell candidates why they SHOULDN'T join. The right people lean in harder. The collection challenges conventional hiring wisdom with actionable frameworks for building exceptional founding teams. **Have questions about these frameworks or how to apply them?

Patrick Collison explains what most startups get wrong pre-product/market fit

Patrick Collison discusses common mistakes startups make before achieving product/market fit, emphasizing the importance of iteration speed and strategic hiring. He suggests that startups should focus on tightening their feedback cycle with initial users and avoid hiring too many people, as the cost of hiring isn't linear but rather quadratic due to increased communication complexity. Collison recommends keeping the team small, between 2 and 10 people, to maintain responsiveness and speed. He prioritizes hiring people who can help build the product quickly. The insights are derived from a Y Combinator talk by Collison in October 2018.

Key Takeaways

  • Startups should prioritize speed of iteration and responsiveness to user feedback before achieving product/market fit.
  • Hiring too many people can decrease a startup's responsiveness due to increased team management complexity.
  • The optimal team size for early-stage startups is between 2 and 10 people, depending on the product being built.
  • Strategic hiring focused on product development is crucial for maintaining speed and responsiveness in early-stage startups.

Keith Rabois: “The velocity of your company improves by adding barrels”

Keith Rabois shares his 'Barrels and Ammunition' framework for building effective teams, arguing that adding 'barrels' - extremely talented individuals who can take ideas from inception to fully shipped product - is key to improving a company's velocity. He contrasts 'barrels' with 'ammunition', ordinary employees who don't significantly impact the company's throughput. Rabois emphasizes that true 'barrels' are rare and difficult to find, and companies should incentivize and retain them with equity, promotions, and other benefits. The framework is based on the idea that adding 'barrels' can exponentially increase a company's productivity, whereas adding 'ammunition' has limited impact.

Key Takeaways

  • The 'Barrels and Ammunition' framework highlights the importance of identifying and retaining exceptional talent in driving company growth and velocity.
  • Companies should prioritize acquiring and incentivizing 'barrels' - individuals who can take ideas from conception to completion - as they have a disproportionate impact on productivity.
  • The rarity and cultural specificity of 'barrels' make them challenging to find and retain, requiring companies to offer significant incentives and tailored approaches.

The Law of Crappy People (and What to Do About It)

Venture capitalist Ben Horowitz explains 'The Law of Crappy People,' a phenomenon where teams in large organizations converge at the point of mediocrity. He suggests that employees benchmark themselves against the worst performer at the next level, leading to a convergence of talent at that level. Horowitz proposes a solution involving clear definitions of responsibilities and skills required for each level, along with a 'promotions council' to review promotions. This approach is likened to a karate dojo, where advancement is based on demonstrated skill rather than subjective judgment. The article discusses how organizations can avoid the tendency towards mediocrity by implementing a fair and transparent promotion process.

Key Takeaways

  • Organizations can avoid mediocrity by implementing clear definitions of responsibilities and required skills for each level.
  • A 'promotions council' can help ensure fairness and transparency in the promotion process.
  • The 'Law of Crappy People' phenomenon occurs when employees benchmark themselves against the worst performer at the next level, leading to a convergence of talent at that level.
  • Ben Horowitz's solution is inspired by the promotion process used in a karate dojo, where advancement is based on demonstrated skill.
  • By adopting a more rigorous and transparent promotion process, businesses can combat the tendency towards mediocrity and promote higher-performing teams.
