Talent is your principal asset; hire the right people and they will find solutions to difficult problems, discover business models, recognize new opportunities, build new products, shape company culture and ultimately recruit other talented people.
Said another way, outlier execution ultimately revolves around people - quality, fit to the specific context, and how they are harnessed.
Given the importance of getting people decisions right, you would likely assume that most leaders are proactive, thoughtful and deliberate about the people they hire.
The latter needs people with proven strengths who 'know' how to scale and have seen the movie before.
Start-ups evolve rapidly so if you hire people that are right 'for now', its likely you'll outgrow them in 12 months.
Speak to people that you know well, have seen high-quality people and will tell you the truth.
