Founder and chief executive Jeromy Wells told Business Insider that the company ended up raising more than $15.6 million in the 2016 calendar year, a higher figure than in September when a $11.75 million series A round was first revealed.

That’s enabled the venture to take its headcount from 70 to now 140 in just 12 months, with even more to come.

“We plan to expand significantly… This year we’re going to add on another 250 staff,” Wells said.

Telstra Ventures, NSI Ventures and Rippledot Capital backed the company in last year’s series A. Whispir, founded in 2002, describes itself as a communications-apps-as-service provider, with Telstra itself one of its major customers. It allows clients to create content like alerts on timetable changes and service outages, with targeted, tailored messages to end users.

The company needs more hands because it has seen 56% compound annual growth from the 2015 to 2017 financial years. It has also cited 68% annual growth in transactions per customer.

While the year end numbers are still preliminary, Business Insider understands the company is looking at around $21 million of revenue for the 2017 financial year.

“China is fascinating – I think it’s a really market opportunity.”

A series B capital raising round is now in the works, with hopes that it could be wrapped up by the end of the year. A public float is also a possibility in the longer term.

“I’m of the strong view that a business needs to generate at least $150 million annual revenue before you go to [the IPO] market. We’re hoping to get there by 2020.”
