The $US65 billion ($88 billion) private equity giant General Atlantic has made its first investment in Australia, tipping $100 million into aged and disability care platform Mable to kick off a broader Australian push inspired by what it sees here as a wave of technological disruption over the past 18 months.

General Atlantic is a pioneer in what is known as growth equity and was founded in 1980 by US entrepreneur Chuck Feeney, who built a duty-free shopping empire before deciding he wanted to give the vast bulk of his fortune away well before he died.
