We raised money and are looking for core hires. Given our personal bond, we would like the core team (first 3-4 hires) to share our passion to some degree. Perhaps naively we'd like them to become pillars of our company and help us inspire future employees.
A former colleague of mine came forward, very bright and capable guy. Exactly the technical talent we need. He likes the project, but he offered to work three days a week for us because he would like to continue working on personal projects in parallel. While I appreciate his honesty, I cannot easily decide if he is the right kind of first hire. Had he joined us a year later, I would hire him in a heartbeat. But right now I feel like lack of commitment from him could possibly influence our culture in a negative way. Is this a right way to think about first hires? What would you do?
