Episode 6 gets right to it with late-night rapid-fire questions, and that can only mean one thing: that a select few are about to compete for the titles of Most Investable and Most Valuable companies. But, you'll have to wait for the finale to find out which top four will earn these honors. While some contestants face the heat, the rest are outside by the firepit, swapping entrepreneurial war stories and getting to the heart of things.The next morning, we meet more contestants before the day kicks off. Our fourth lesson of the season demonstrates the differences between startups and small businesses, and what each can learn from the other. Spoiler alert, it's a lot.The challenge requires contestants to present a piece of tech they're using (or plan to use) to create more value, a contractor they've hired (or plan to hire), and a system that allows them to replicate tasks, proving they can scale. Many Bloxers agree that this lesson and challenge were their favorites, and they bring that enthusiasm to their consults.
