The crowdfunding platform Givealittle has been sold to the financial and estate planning company, Perpetual Guardian, for an undisclosed sum.
Perpetual has become known as the company offering its staff a four-day work week.
Its founder Andrew Barnes said it will keep investing in Givealittle, although it will remain a not-for-profit business.
The crowdfunding platform has raised $130 million for charitable causes over its 10-year lifetime, including for victims of the Christchurch mosque attacks and those affected by the Australian bush fires.
The charitable subsidiary of the telecommunications company Spark bought the platform in 2012, but decided to sell it in the middle of last year.
