Know what makes a startup different
A startup searches for a business model that can repeat, grow, and produce profit.
A business model describes how a company creates value, delivers it, and earns enough to continue.
A new business is not necessarily a startup. A small business can use a known model from its first day. A large organization can still search for a workable model. Size and age do not settle the question.
A repeatable model produces value through a process that the business can use again. A scalable model lets the business increase output without the same increase in all costs. A profitable model earns more than it costs to operate. The startup must discover how these properties can work together.
This does not require perfect scale from the first day. Manual work can help a founder learn what customers need. A service can fund development. The important question is whether the business can eventually grow beyond the direct effort of its founders.
A startup can have funding, employees, and attention while its model remains unproven. These resources give it more opportunities to search. They do not prove that customers will support a lasting business. Keep the distinction clear when you describe progress to yourself and others.
