Don’t try to create a new market prematurely. The only way to know you have a real business is to start with an already existing customer, so you should build your company by improving on recognizable products already offered by successful competitors.

The perfect target market for a startup is a small group of particular people concentrated together and served by few or no competitors.

In practice, a large market will either lack a good starting point or it will be open to competition, so it’s hard to ever reach that 1%. And even if you do succeed in gaining a small foothold, you’ll have to be satisfied with keeping the lights on: cutthroat competition means your profits will be zero.
