Instant
Instant is a Sydney-founded, AI-powered retention marketing platform for ecommerce brands. It identifies anonymous shoppers, recovers abandoned carts and sends AI-generated email and SMS at the moment of highest purchase intent. After starting life as a one-click checkout tool in 2021, Instant pivoted to retention marketing and grew fast - more than 1,500 direct-to-consumer brands now use it, and the company says its AI-driven flows have generated over $1 billion in incremental revenue.
Mario Gabriele
Mario Gabriele is the founder and writer of The Generalist, a long-form tech and venture newsletter with 163,000+ subscribers ranked among Substack's top business publications. Raised in England by an Italian father and American mother, he cut a nonlinear path through law, culinary school, fiction writing, and seed-stage VC before going full-time as a solo creator in 2020. His signature style - combining equity research depth with fiction-writer storytelling - earned him citations in the FT, WSJ, and Bloomberg and attracted a loyal paid following. In 2022, he launched Generalist Capital, a $12.25M solo GP fund, and by March 2026 he had joined Hummingbird Ventures as a full Partner.
