Angels are wealthy individuals, often with personal entrepreneurial experience, who band together in groups to invest in early-stage firms.
Four local start-ups are also travelling to San Francisco next week to attend an event at the Kiwi Landing Pad - an organisation which helps New Zealand tech companies establish and grow their businesses in the US.
Erskine said the event would give companies a chance to pitch their business plans to a panel of US-based New Zealand entrepreneurs, including Claudia Batten - one of the founders of video game advertising firm Massive, sold to Microsoft in 2006 - and Victoria Ransom, who sold her social media marketing firm Wildfire to Google for US$250 million ($292 million) last year.
The start-ups are intellectual property solutions provider Parrot Analytics, BigLittleBang, which has developed an online 3D virtual world for children, agri-tech business CropLogic and biotech developer PolyBatics.
BigLittleBang founder Chris White, who will be travelling to California, said the trip would also provide the opportunity to pitch to US angel investors.
"We're looking for advisers and potential board members in the US," he said. "We're looking for expertise [from people who] also want to have skin in the game."
White said the US was BigLittleBang's biggest market and the company was looking to establish a presence there.
