Investing in new ideas can be tricky because it's hard to predict the outcome. When companies don't have enough money to fund their innovative projects, it can slow down progress. Smaller and newer companies, as well as those working on big changes, are more likely to struggle with getting the money they need. This can happen when they can't use their own funds or when it's tough to borrow money at a good rate. So, the size of a company, how long it's been around, and the type of innovation it's working on all play a role in how easy or hard it is to get the money needed to keep moving forward.
