A founder introduction works best when it is short, specific and easy to discuss. The aim is not to impress with polish but to make your thinking visible.
Bring the customer and the problem in a sentence or two, and what they do about it today. Describe your solution and the evidence so far, whether conversations, pilots, usage or revenue, stated plainly. Introduce the team and why you are suited to this problem.
Explain how the business could earn revenue, and name the next milestone along with the help you are looking for to reach it.
A concise deck or one-page summary is useful, but evidence matters more than design. Be clear about what you do not yet know; it makes the conversation more productive for everyone.
