Norton says the funding round takes the total 90 Seconds has raised since its 2010 launch to around $13 million.
He said the latest capital injection gave the firm "a real shot at positioning the company globally".
"There's going to be a lot of competition in this space and a lot of heat around business models."
The company had 68 full-time staff across offices in Auckland, Sydney, Singapore, Manila, Tokyo and London.
"I'd imagine we'll double the staff numbers on this investment across the full range of activities," said Norton, who holds a roughly 22 per cent stake in the firm.
New offices would also be opened in San Francisco, New York and Hong Kong, as well as a European operation in either Amsterdam or Berlin.
"Those bases will be set up in the next six months," Norton said.
He said 90 Seconds' revenue had grown about 300 per cent in the past 12 months and the firm, which was hovering around break-even, was now posting annualised sales of roughly $20 million. "We've got a pretty strong month-on-month growth curve."
Sequoia Capital vice-president Pieter Kemps said 90 Seconds had created a unique technology platform. "This has enabled them to build a fast-growing and rapidly scaling model," Kemps said.
California-based Sequoia has invested in many of the global heavyweights of technology, including Apple, Google and Airbnb.
Norton said 90 Seconds would eventually carry out an initial public offering, possibly in New Zealand, or look to be acquired by a trade player.
