My family and I have built many businesses, grown many businesses through hard work and acquisitions. The majority of them successful and some, as
@STuDioSuRFiNG says, the rip cord was pulled or changing markets were difficult to keep profitable, big corporate competition was to hard to keep up with financially and other reasons.
Of the business' we've been in, I found that there is a key common denominator when things don't go so well. Ownership presence. There is a reach that becomes to far to keep hold of. You can have all the passion in the world for a business, but, if you're not there every day to care for it, costs will rise, operations wont always run the way of your vision, and even with the most trusted management team it will be less profitable.
You have to wake up each day with the passion to "get to the office" and "get things moving". My dad started every day walking through the warehouse, seeing the state of inventory, talking to the employees, warehouse people, truck drivers, mechanics, custodians and the like. He wanted a feel for the company and the folks that worked for him and if they all shared his vision on how the company ran, get their ideas on how things should run. Every employee knew who "pepe" was and really knew him, more than "oh there's the boss". I believe that remote business' don't have that key factor if the ownership isn't present every day nurturing and caring for it and its team. When the work day was over for our team, he left work, not for the day, but to then go visit the customers to nurture relationships with them and assure them of quality products, service and promotion. Partners, not customers.
Living far away from the business had to be hard for David. He had to count on others to care for his company and I think he had that with Jim B who was the previous owner and ran things for him like it was still his own, with pride. It has to be hard to not be able to walk through the plant each day, inspect the machinery, talk to your employees, see how things are going, inspect each run etc. especially after Jim's death, so I can see how a decision to sell a company arises.
I see all kinds of people on the 2 key forums in our hobby talking about how easy it would be to fund up and buy the company, but in my eyes that is all fantasy, well unless you are going to take the time and effort to relocate and be there every day and care for the investment and produce a quality product, truly take the risk of a capital investment in a business you love. IMO A large group of people partnering up with so many different visions of a business that they know nothing about would be a recipe for disaster. This isn't Paulson where there is room for error, a sales staff hawking the products to endless customers, it is a specialty company that requires a lot of attention and care by its principal. Fantasy is fun, Business and the money it takes is real life.
I wish David and David the best in whatever endeavor they go on and hope that the CPC company finds a new owner with the passion and ability to continue and grow. When a company comes for sale in this world there is always a reason, some you hear and some you don't. Just the time and effort to explore a "deal" will be great for a perspective "buyer" and "seller" of their legacy and vision will be great. From our hobby perspective it would be sad to see an outlet like this go away but a business must be viable and desirable to it's owner(s) to succeed.
