Agriculture technology-focused venture capital firm Tenacious Ventures has overcome multiple delays and a need to scale back its cash-raising goal to win the backing of several high-profile investors, and hit $18 million for its second fund.

The Sydney-based fund’s new investors include Reserve Bank of Australia board member Carol Schwartz’s Trawalla Group, and Tesla chair Robyn Denholm’s Wollemi Capital Group. Macdoch Ventures, which invests for Rupert Murdoch’s daughter Prudence and her entrepreneur husband Alasdair Macleod, is also returning to back Tenacious.
