Zipmark Inc. was a Y Combinator-backed startup that developed a secure online payment service for businesses to send and receive digital checks. The platform aimed to offer a faster, more secure, and less expensive alternative to physical checks by leveraging the ACH network. The company primarily targeted B2B transactions, including rent payments for property management companies and invoice payments for small businesses. Despite raising venture capital, Zipmark officially ceased all operations and shut down its services in late 2015.
