A pair of Mt Maunganui brothers have turned their app idea into a $30m tech business, disrupting the lucrative United States sports sponsorship market.

Brendan Howell, 40, and Peter Howell, 37, founded DROPIT in the Mount in 2015, building on technology from a previous enterprise.

A reverse auction app platform, DROPIT counts down the price of an item to $0 in 60 seconds. The clock stops when someone buys it.

Peter Howell spoke with Rachel Smalley about the new app.
