There are 3 main tips I recommend to all founders starting out, who have plans to build a Really Big Company:
1) Write a 1-page Master Plan, similar to Elon’s early Tesla plan. This forces you to clarify your vision & think holistically about how you’ll execute. These end up becoming talking points you’ll use to pitch Investors, Employees, and potential Clients.
2) If you have a product live, carefully monitor growth. Investors will be most interested in high Week-over-Week growth of 10-15%. This seems obvious, but most pitch decks don’t include weekly growth charts (of revenue, users, etc).
3) Have fun! It’s a long journey so you should be excited each day about what you’re building.
