An angel investor uses personal capital to back startups before institutional VCs come in.
In Sydney, angels range from individuals writing A$25K-A$200K to family offices deploying millions.
The Artesian Sidecar Fund invests A$100K-A$500K alongside Sydney Angels members. Browse New South Wales investors for broader NSW context on how angels and VCs co-invest in the region.
Most angels in Sydney join syndicates to access better deals. Review how investors run due diligence so you know what angels check before they commit.
Australia is still in a very nascent stage when it comes to angel investing.

How angel syndicates work in Sydney
Syndicate platforms pool small cheques from many investors into a single investment vehicle.
Aussie Angels hosts 50+ syndicates with minimums as low as A$1K per deal.
A lead investor sources the deal, does diligence, and invites their network. Browse Sydney startups resources to understand what stage and structure works best for your raise.
Syndicates let founders close larger rounds faster without chasing dozens of individual angels.
What Sydney angels look for in founders
Sydney angels back founders first. The idea matters less than the person pitching it.
Traction helps, but angels at pre-seed stage fund potential, not just proof.
Prepare your documents before outreach. A well-structured pitch deck with trackable links shows angels you're organised and serious about your raise.
Don't burn goodwill by sending 40-slide decks cold. Send a one-pager first, then share your data room.
Setting up your data room for angel outreach
Angels move fast. You need documents ready before your first meeting, not after.
Core documents: financial model, cap table, product demo, and a one-page summary.
Use Ellty to upload everything once and share individual links to specific investors. You'll know who opened what and when.
See what the full due diligence process looks like so you can prepare the right documents before angels request them.
