Thank you for the strong response to our call for help identifying the world's most intriguing new companies. We're in the process of looking over more than 200 candidates and will publish our findings on Nov. 11.

BusinessWeek is excited to announce a new editorial project to showcase the most intriguing new businesses on the planet.

To identify the most compelling new businesses, we want to tap the brains of our readers and the public at large. So we invite you to send us your ideas.

What defines most intriguing? To us, that means new enterprises that generate the most interest or fascination; the businesses that are working hard to solve the world's most important problems. The game-changers that make you say, "Wow, that's really interesting." They don't necessarily have to be the fastest growing or the most well-known or the most financially successful businesses, though those are desirable qualities.

These businesses could be for-profit ventures or they could be non-profit. They could come from any industry. However, they should not be more than three years old.

Twitter is a perfect example of an intriguing business. The Internet communications tool is having a huge impact on business and politics but it is not yet profitable. Kiva, a Web service that enables individuals to make small loans to one another, is example of an intriguing enterprise in the non-profit arena.

We will place a premium on those companies that readers may not know. We think that will make the list more interesting, useful and surprising.

Over the next month we invite you to send us your best examples. The deadline for submission is Friday Sept. 25. Your entry should contain no more than 200 words and describe the business and what makes it most intriguing. We will publish our list of the most intriguing businesses on Oct. 22.

Thanks in advance for your interest and help. We look forward to hearing from you.
