Adelaide AI email startup Nitrosend raises $700k seed
## Adelaide AI email startup Nitrosend raises $700k seed Nitrosend, an Adelaide-based AI email marketing platform, closed a $700,000 seed round led by Eastend Ventures, with participation from Archangel Ventures and Aussie Angels. The company was founded by brothers Edward and George Hartley, who previously built SmartrMail, an email automation tool that scaled to 6 billion emails sent before being acquired by Relay Commerce in 2022. They brought back their former CTO, Kam Low, as a founding team member for the new venture. ### What they are building Nitrosend positions itself as an AI-native email platform. Instead of drag-and-drop template editors, users describe campaign goals in natural language (via Claude, ChatGPT, or the Nitrosend platform), and the system handles writing, design, sending, and performance reporting. The platform also automates workflows like welcome sequences, cart abandonment, and customer segmentation. Target market: SMBs that lack dedicated marketing resources or agency budgets. ### Early traction The company signed 190 users since April 2026, including early-stage startups Elita Genetics and Fast Lane. No public customer count, revenue, or sales headcount disclosed. ### Market context Nitrosend sits in the crowded AI email marketing segment alongside Mailchimp, Klaviyo, ActiveCampaign, HubSpot, and newer AI-native tools. Their differentiation: 10 years of email infrastructure experience combined with AI workflow automation. For sales teams evaluating martech stacks, the platform could reduce reliance on marketing ops resources for campaign execution, though enterprise buyers will want to see more proof of scale. Eastend Ventures founding partner Josh Garratt: "Experienced founders going after a market they already understand better than anyone, at exactly the moment that market is being reshaped by AI." Worth noting: the company appears to be operating with a founder-led commercial motion rather than a dedicated sales org at this stage. No sales hiring announced.
