Hard-to-Find Niche Market Analysis Is Our Specialty

Marketdata Enterprises, Inc., founded in 1979, has been publishing independent market research studies for 45 years. Marketdata is a privately-owned corporation based in Tampa, Florida. We are engaged in the following activities:

  • Publishing off-the-shelf, multi-client market and industry studies
  • Custom Research
  • Consulting
  • Website Development

We focus on analyzing SERVICE and HEALTHCARE sectors
, usually niche markets that no one else has analyzed. Most importantly, our research is NOT funded or commissioned by anyone–so it’s always unbiased.

Our market studies are sold direct, and are also available via marketing research distributors and online business databases such as: Marketresearch.com, Research & Markets, Global Information Inc., PharmaceuticalMarkets.com, and Profound. Most market reports are also available via electronic business databases, for a fee.  Here, one can download as little as one page from our reports.

As Your Marketing Research Source, we also perform Custom Market Research projects and Management Consulting, including phone and online surveys. Basically, we can find information on ANY topic or market, quickly and inexpensively.

  • Assess competitor strategies
  • Identify key issues affecting demand

What Makes Us Different…

We specialize in service industries only

  • Reports can be purchased by chapters. The buyer can pick and choose only the sections they need without having to purchase the whole study. Many publishers do not offer this option.
  • Marketdata reports usually include historical revenues/market size going back 10, 15, or 20 years. We believe that it’s important to look at a market over the long term, through various market cycles, recessions, and expansion periods – we do not forecast based on short term trends.
  • We use a comprehensive mixture of primary and secondary research, consisting of information from public and private sector sources, mail and phone surveys, internet research, government agencies, trade associations, and more.
  • Each market study is “custom crafted”. Each market has its own special nuances and characteristics. Consequently, reports can not be put into a cookie cutter or boilerplate format.
