Many Internet-based tools are cutting edge. It follows that they often are offered by small and innovative entrepreneurial companies. These companies in many cases are ahead of the more established vendors and service providers. Older companies have longer decision making processes, don't rely on one product or product family for survival and, in general, react more slowly to market forces.
The problem is that these smaller companies often go out of business or are acquired.
Small companies must recognize that dealing with cutting edge vendors adds a layer to the risk/reward calculation. Planners must strike a balance between the newcomers and established players. No matter how great a new gizmo or service offering is, a small business runs a risk in dealing with a startup.
There is, of course, no reason not to use a small vendor. Indeed, no organization has better reason to do so than a company that itself is small. Proper caution must be exercised, exercised. Small businesses must perform an extra level of due diligence. Some questions: What guarantees does the buyer have if the company is acquired? Will the buyer have access to key documentation if the company goes out of business or is bought? Are there third parties the buyer can call on to support the products? In general, the key to this line of inquiry is to ensure that no matter what happens, the buyer is as protected as possible. If managers are comfortable that they are secure, they can have the best of both worlds: Cutting edge, innovative technology and a clear sense that the company will not be left to fend for itself.
