About Jamie Mackay
Jamie Mackay is based in Sydney, Australia. Crunchbase lists him as Founding Partner and Chief Strategy Officer at BWM Dentsu, a role it dates from June 1996. It also says he studied at Macquarie University.
BWM Dentsu is a marketing agency. His public investing activity so far connects to that industry, where he is named as an industry backer of an agency-focused AI startup.
In April 2026, Manifest announced its launch with a $2M pre-seed round. SecurityBrief reports the amount as AUD $2 million. Brand Fund by Previously Unavailable led the round. Antler, Icehouse Ventures, Techstars, the Huljich & Bhatnagar Family Offices and a group of industry angels also took part. Press coverage names Jamie Mackay of BWM Dentsu among those angels.
Manifest describes itself as an AI-powered operational intelligence platform for agencies. It captures how work happens across teams, tools and AI, and maps time, effort and workflows. Its aim is to help agencies understand where work is created, how it flows and what it costs to deliver. The company is rolling out with agencies in Sydney, Melbourne and Auckland.
Jamie Mackay has not published an investment thesis, check size or stage preference that we could find. The one round on record is a pre-seed AI round for a company selling to agencies in Australia and New Zealand. The other angels in that round are mostly from agency, media and marketing businesses. That suggests he backs founders whose products he understands from the agency side. It is an inference from a single deal, not a stated policy.
