The components of a business model involve these three essential ingredients:
1. Service (i.e., linen service) or product
2. Acquire a customer
3. Generate revenue from that customer
You have a successful and profitable business model when revenue (#3) is greater than the cost of the service (#1) + sales and marketing (#2).
At its core, it really is that simple.
When you have found the right service and market, now you may want to monetize your service most effectively and begin to scale it.
Have you figured out your business model; are you making sure you nail the model before you start to scale; does this model provide you with a way to generate significant revenue from the business.
Are you scaling at the right time; are you making sure you're not moving too early or too late?
Are you willing to bring in new people with the specialized skills necessary to help the company succeed in its growing form? Are you also willing to make the right decisions about your current people (including yourself), insisting that they go from generalist to specialist and letting them go if they can't make the transition?
Have you raised the necessary revenue to scale, either from increased revenues or from venture capital?
Are you resisting lowball offers? Do you understand the pitfalls of entertaining or accepting such offers?
