Watch this house

Sometimes, starting a small business can lead an entrepreneur to discover a much bigger idea.

Consider Diane Pisani, who opened a company in Naples in 2006 called Your Home Watch Professionals. She quickly developed a following among seasonal residents who needed a professional to look after their second homes in Naples, but she couldn't find anyone reputable to take on the overwhelming additional demand for her services.

In that process, Pisani realized that she could build a bigger business by teaching people how to start their own home-watch companies. She's created training seminars that help prospective entrepreneurs start their own companies catering to seasonal residents.
