About Andrew Poesaste

Andrew Poesaste came into venture capital after spending about a decade building low-latency algorithmic trading technology, then six years investing across Europe and Israel at Angular Ventures, giving him a technical and international perspective before joining Rampersand. He now focuses on backing founders with real technical depth, staying close to builders through things like judging the OpenAI Codex Hackathon in Sydney, connecting ANZ startups with labs like Anthropic and OpenAI, and still coding and shipping products himself.

Rampersand is a venture fund for ANZ-born founders building anywhere in the world, with a process built to be checked by founders themselves: a sub-two-week path from first meeting to signed term sheet, reference calls with founders they've disagreed with, and a written framework (What Do We Need To Believe) that lays out the specific beliefs behind each investment. They focus on AI-native software, vertical AI, and areas where software meets physical industries like hardware and robotics, backed by concrete efforts to connect founders with customers and specific companies through named intro paths.
