Maersk Line says it has made an investment in US-based freight booking start-up New York Shipping Exchange (NYSHEX). In addition, it plans to offer container space through the company's service.

NYSHEX received $8.5m in seed financing from last March. NYSHEX did not disclose the size of Maersk's investment, just that it is now a "founding member."

Maersk joins Hapag Lloyd, CMA CGM, MOL, OOCL, and COSCO as carrier members, the exchange said.
