Nobody knows who better to hire than the founder of a super early stage startup (< 5 people). The founder knows exactly what issues need to be tackled, has the most information about the product/service being sold, and knows what kinds of people they mesh well with. Bringing in a recruiter at this stage is not only wasting vast amounts of precious startup capital but could also thoroughly damage or kill the startup because wasted time, effort, and improper direction.
I thought hiring is broken and basically all are bad at it.
