Manifest is an AI-powered operational intelligence platform for agencies. B&T reported its launch and the $2 million pre-seed round on 29 April 2026. The company says it replaces manual time inputs with real-time operational data, so agencies can see where work is created, how it flows and what it costs to deliver. It is described as Sydney-based and founded by Freddie McKenzie and Henry Collinson.
Isaacs has not published a thesis, preferred stage, sector list or check size that we could find. His one confirmed AI investment was a pre-seed round in an AI product for the agency and marketing services industry, in Australia and New Zealand. One deal is not enough to define a focus, and his check size in Manifest has not been disclosed.
