Market Position
George positions his work as an AI-native alternative to dashboard-centric email platforms: the agent is the interface, the marketer directs rather than drags blocks, and human approval remains in the loop. Nitrosend is differentiated by MCP-first operation, REST/API/SDK/CLI coverage, brand-context memory and no per-contact pricing; the conventional alternatives discussed around the product include Klaviyo, Mailchimp, ActiveCampaign, HubSpot, Resend, Postmark and SendGrid.
Leadership
Founders
George Hartley
Australian founder and product builder; co-founder and former co-CEO of Bluethumb, co-founder and former CEO of SmartrMail, Startmate mentor, and angel investor in 30+ startups.
Founding Story
After co-founding and running SmartrMail, George observed that customers spent hours dragging composer blocks to do work AI could perform in seconds. After SmartrMail's 2022 acquisition non-compete expired, he and former SmartrMail CTO Kam Low began building Nitrosend in February 2026 to solve the problem for their own marketing, bringing Edward Hartley and the former SmartrMail team into the venture. George first addressed AI's weak email-marketing knowledge by publishing the free Email Marketing Bible, then built an AI-native platform that removes the dashboard as the main operating surface.
