It was great working with Half Eaten Donut on Sydney Contemporary. They were proactive and responsive and know the event space extremely well. They were available for any last minute requests at any time before, during and after the event. The results from the digital campaign were also extremely good and we exceeded our ticket target. Overall Sydney Contemporary was a very successful event and we couldn't of achieved the results we did without the team from Half Eaten Donut!

We were super impressed with the results the Half Eaten Donut team were able to generate during our campaign! They were easy to deal with, knowledgeable, quick to respond and most importantly nimble in their ability to optimise the program and take advantage of real-time opportunities. Would highly recommend working with them across any of your digital projects. They smashed the targets and we are excited to work with them on our future projects!

SXSW Sydney 2025 has claimed a total event attendance of 345,000, marking a 15% increase from the previous year. The event also saw 105,000 unique attendees, representing a 10% increase year-on-year. We selected Half Eaten Donut based on glowing recommendations from industry clients who operate in this space. Their track record in event marketing, combined with a data-led, audience-first approach, made them the right fit to help drive both awareness and ticket sales for SXSW Sydney 2025. Half Eaten Donut has contributed to SXSW Sydney registering significantly more passes and tickets year on year and enabled meaningful collaborations with the Museum of Contemporary Art Australia and Sydney Contemporary. These partnerships have helped strengthen the brand, increase visitation and boost registrations across all three events.

I couldn't be more impressed with Half Eaten Donut. The strategy they put together for our show allowed for quick, targeted wins as well as long term goals and the results they achieved in one campaign far exceeded our expectations. They allowed us to expand our digital reach and campaign activity and introduced us to new marketing channels that will be important components for future show campaigns.

We were recommended Half Eaten Donut from a colleague and we're glad we invested with them for our launch event. From strategy planning to weekly WIPs and daily emails from me, there was never a task too small for the team at HED and no question too unimportant to answer. They're great to work with and an incredibly agile team.
