In my current startup, I'm the de facto "business" co-founder. I want to be investing time in learning hard skills that will help us now and in the future so that I can be better prepared.<p>Below is the list I have so far. What's missing? I'd also love to know what you recommend I use to learn each topic.<p>1. Financials
2. KPIs for different areas of the business
3. Hiring
4. People management
5. Fundraising
6. Strategy
7. Marketing
What I’ve observed is more of a:<p>1) Identify biggest problem/opportunity in the company<p>2) Learn what is needed to solve it<p>3) Hire someone to take over what you’ve been doing<p>4) Repeat<p>Rather than any kind of topic based learning.
