The nine-strong brand, known for its Aussie brunches and coffee, hit its initial £500,000 target just hours after launching its Crowdcube page a month ago.
It has now ended its campaign, having quadrupled its goal with the help of 792 investors.
According to Daisy Green’s business plan, it is aiming to use the funds to grow to at least 17 sites with revenues of over £25m within four years.
The group was founded in 2012 by Australian entrepreneur Prue Freeman and her husband Tom Onions. It began as a street food trader serving coffee and frozen yoghurt at markets and festivals.
Daisy Green now runs nine sites across London, including two floating barge restaurants in Paddington.
Its most recent opening, Scarlett Green in Soho, offers brunch, lunch and a wider dinner menu alongside what it claims is the capital's largest Australian wine list.
Daisy Green’s expansion will also be supported by a £3.4m debt finance deal it secured with UK bank OakNorth last year.
