In a roundup of news from this week, Adyen announces significant growth, Stripe upgrades its Atlas program, Mastercard is taking applicants for summer Start Path Global program, and Wirecard and Alipay continue their expansion.

Dutch payment facilitator Adyen announced that its 2016 revenue was $727 million. That number is up 99% from the previous year’s revenue of $365 million, the company said.

Adyen said that some of its recent client additions include WeWork, Sephora, Symantec and Microsoft.

Stripe announced changes to its Atlas program this week. Atlas is a tool that streamlines opening an e-commerce business in the U.S., handling incorporation paperwork and opening a bank account, among other services.

The company has opened the program, which was originally targeted to non-U.S. businesses, to U.S.-based founders. It also announced the expansion of the Stripe Atlas network of investors and the creation of the Atlas Forum, a discussion board for members.

Mastercard named the startups it is accepting into its Start Path Global program for its spring wave. It chooses participants from companies that are innovating in banking and payments, and that have already raised significant investment.

This round of participants includes NetPlusDotCom, a Nigerian digital payments company and owner of payment facilitator NetPlusPay.

“Fintech startups around the world are designing a digital future,” said Amy Neale, vice president, Mastercard Start Path. “They’re bringing a different approach to enhance customer choice and experience across the industry. Our work with these startups helps connect new technology with reliable, secure financial networks and processes to create an even more rewarding and seamless commerce experience.”

The company is also now accepting applications for its summer Start Path Global program.

Bluefin Payment Systems announced that it would provide its PCI-validated point-to-point encryption system to clients of Clearwave. Clearwave offers healthcare organizations a self-service patient check-in and registration system. The solution will be used for patient co-payments on the system, encrypting the data and reducing PCI scope for providers.

The relationship between German payment facilitator Wirecard and Alipay is now expanding access for Chinese tourists in Germany and Greece. Wirecard announced that it is working with the National Bank of Greece to enable Greek merchants to accept Alipay as a payment method.

It also has an agreement with German drugstore chain Dirk Rossman GmbH to offer Alipay at all of the Rossman stores across Germany.
