"This isn't their first rodeo," Eastend Ventures founding partner Josh Garratt said. "They've built and sold a successful email marketing business before, and now they're back to do it again for an AI world."

Why now? AI is reshaping how businesses create content, and email marketing — still a workhorse channel for online businesses — is ripe for automation. Edward Hartley said businesses he's worked with spend 45 minutes to an hour crafting a single email. With Nitrosend, a prompt can produce a polished email in five minutes.

The product has been in beta since April, with roughly 190 users onboarded and email volume doubling weekly.

What could go wrong? The AI email marketing space is getting crowded fast. Established players like Mailchimp and Klaviyo are adding their own AI features, meaning Nitrosend will need to move quickly to carve out share before incumbents catch up. A $500K seed round also leaves a thin runway if user growth stalls or acquisition costs climb.

The signal: Nitrosend's seed round is a small bet, but the thesis behind it is clear: repeat founders who already built and exited in the email marketing category are now rebuilding for an AI-native era, backed by a regional fund purpose-built to keep South Australian startups local. With incumbents like Mailchimp and Klaviyo bolting AI onto existing platforms, the real test is whether a ground-up approach — and a thin $500K runway — can generate enough traction to raise a meaningful follow-on before the window closes.
