Online teaching or tutoring is a great business to start with little or no capital because it requires minimal investment—just a computer, internet connection, and knowledge in a subject. Platforms like Zoom, Google Meet, and WhatsApp make it easy to connect with students, while websites like Udemy, Teachable, and YouTube allow you to monetize recorded lessons. With high demand for education, flexible working hours, and the ability to reach a global audience, online tutoring offers a scalable and profitable income stream.
