Good readings for a CEO/CTO to grasp basic CFO notions

Nowadays more and more startups kickstart with a strong technical knowledge base. Sometimes the common scenario includes a low, if not completely absent, finance knowledge. I'm not talking about basic economy/financial knowledge that impact business plans. Is more about having a big picture of the growth process in the mid/long run.Talking about funding, IPOs, stocks admin, forex. From a tech-CEO/CTO point of view, I do believe is important to have a rough understanding. What would you suggest as a good reading? What pitfalls to look after? Thank you
