Recently, BusinessWeek and YouNoodle collaborated to list the top 50 online startup companies in the tech world. The resulting list is comprised of many promising startups that could eventually become household names like Google, Facebook, MySpace and Twitter.

While some somewhat well-known startups are including in the list — such as Project Better Place and Cloudera — many of the online startups are unknown to the vast majority of internet users.

Their list, which they call “Fifty Tech Startups You Should Know”, they list the company name, the headquarters location, the amount of funding the startup received, the year the startup was funded and the name of the company’s CEO. Additionally, the chart lists the YouNoodle score, which mearures the progress of the startup.

While most of these online startup companies are located in the United States, other companies represented in the list include England, Spain, India, Israel, Brazil and Argentina.
