The last week of April is scheduled to see eight different companies go public, and Zacks has you covered with three unique IPO offerings to watch out for.

The wide-ranging list of companies set to go public this week will help contribute to an already booming 2017 for the IPO world. Since Jan. 1, 36 IPOs have been priced in the U.S.—not including this week’s offerings—which is up around 177% year-over-year.

These three IPOs cover finance, big data, and biopharmaceuticals. Check them out:

China Rapid Finance

The Shanghai, China-based online credit company, China Rapid Finance Ltd., is China’s largest online consumer lending marketplace. China Rapid Finance has tapped into the company’s massive and growing middle class, which is estimated to be over 500 million people. Many of these people normally don’t have access to bank credit.

China Rapid Finance targets individuals online and through mobile devices who have quality employment records but no credit history. The company refers to these people as “Emerging Middle class Mobile Active.” China Rapid Finance is a massive online consumer credit marketplace that makes its money from recurring transaction and service fees from both borrowers and investors. According to the company, China is the world’s largest untapped consumer credit market, and it is expected to grow into an $870 billion market by 2020.

The company uses algorithms and metrics in its mostly-automated system of finding credit-worthy individuals online. China Rapid Finance’s typical consumption-based loans are normally worth less than $865 for 3-month terms. However, the company does offer up to $14,400 “Lifestyle” loans, which require greater screening.

Before starting China Rapid Finance, its founder, chairman, and CEO Dr. Zane Wang served as the head of analytics for Sears Holdings Corp.’s credit cards services and advised the People’s Bank of China on the creation of a national credit bureau.
