Any project starts with a model (paper, mental, miniature, prototype, etc).
To validate the model, we ask a variety of questions based on metrics we define. Does it look good enough? Does it sell enough? Do people like it? Etc.
Although these questions can help validate the model, only client referrals can tell you if your business is to have marketing success.
If the community around your business is viable and self-sustainable – every new client bringing in another client (+1) – beyond friends and family, chances are, it will be when more people get to it (Raphael Ettore).
Until then, forget about beta, alpha, etc; build a model that works beyond your circle and expectations. Once the model is sustainable, and only then, take it out of the sandbox and start investing money into marketing.
How likely are people to recommend your current business?
