When a person is pitching their idea or their company, there are some common mistakes that they may make. The first mistake is not being clear about what the person wants. This can be seen in when a person pitches a product or service and does not mention anything about it being free. If someone wants to start an app, for example, they need to mention that it is free before moving on to the next step of the process. The second mistake is not providing enough content for the reader. A lot of people don't know how much content they should provide before pitching their idea or company because it all depends on what you're pitching.
