At YOptima, we value people who are driven by a higher sense of responsibility, bias for action, transparency, persistence with adaptability, curiosity and humility.

And that success needs the creative mindset to deal with ambiguities when you start, the courage to handle rejections and failure and rise up, and the persistence and humility to iterate and course correct.

1. We look for people who are initiative driven, and not interruption driven. The ones who challenge the status quo with humility and candor.
2. We believe startup managers and leaders are great individual contributors too, and that there is no place for context free leadership.
