George Hartley grew Nitrosend to 1,200 signups without a marketing team


Hi Reader,

Picture a founder in his home office in Melbourne. He props an iPhone on a shelf, clips on a mic, and talks straight to camera about a feature that he shipped that morning. No studio, no crew, about ten minutes of footage.

That rough clip is the raw material. Once George Hartley hands it to Claude and a freelance editor, it becomes a launch that pulls somewhere between 100,000 and a million impressions. He has run that motion over and over since June. It carried Nitrosend to 1,200 signups and roughly 750,000 weekly email sends with a team of three people and Claude.

To compare, George also tested paid ads across Meta, Google, and LinkedIn at the same time. They flopped completely. The cheap, scrappy launches got all the results.

I saw this same pattern at SingleStore, where I generated 1,100 organic marketing-qualified leads at about $50 each with zero ad spend. The fact of the matter is, when your company is young, the trust that converts the best always comes from how useful you are in public.

WHAT WE DISCUSSED

  • How George turns every shipped feature into its own launch event on X and LinkedIn
  • His exact lean launch sequence: script with Claude, film to camera, reuse one animation base, run a clipper bounty, blast the warm network
  • Why his paid retargeting and Google search ads fell flat this early
  • How he runs Nitrosend with three people and Claude, where 94% of user sessions never touch the app
  • How he builds an AI memory for each brand, so his email performance compounds over time
  • Why his biggest growth breakthroughs over 13 years came from in-person founder conversations, ahead of anything online
  • How he buys sleepy little websites to acquire an audience and a live test bed

WHERE TO FIND GEORGE HARTLEY

MY BIGGEST TAKEAWAYS

  1. Stop treating launches as rare, big-budget events. The founders who win early package every meaningful thing that they ship as its own small launch. George maps his launches to his product roadmap, so another launch moment is always coming.
  2. Build the expensive parts once. George paid an agency for a single animation base and reuses it on every launch, so each new launch costs him a script and an afternoon. Reuse is what lets three people ship at the cadence of a much bigger team.
  3. Paid traffic can't buy trust that you haven't earned yet. His retargeting and search ads flopped while free, scrappy launches drove the signups. When nobody knows your name, borrowed attention beats bought attention.
  4. Put the agent in the driver's seat of execution. Claude writes George's scripts, cuts his videos, and drafts his one-to-one outbound. A person runs out of memory, patience, and time. An agent doesn't.
  5. Give your brand a memory that the AI can retrieve. Nitrosend scans a brand on onboarding and builds an AI memory that stacks learnings over time. Build your case studies, proof, and voice into the AI so it can pull the right proof point at the right moment.
  6. The breakthroughs that actually matter still happen off the internet. George's editor, and then his animation agency, both came from a single coffee in San Francisco. The alpha on X is already gone by the time you read it, so invest in real conversations with other operators.
  7. Have the hard conversations with your co-founders before you need them. The most common startup killer that he sees is co-founders blowing up with each other. Work through how it could fall apart while everything is still fine.
  8. Build something that you are the user of, or close enough to stand in the buyer's shoes. This is George's third email company, so he knows this buyer cold. When you understand the product and the buyer that deeply, you stop guessing and start engineering.

If you are a technical founder who is building slightly ahead of your market, George's playbook is a rare look at how to grow with almost no budget and a very small team. It is lean and repeatable, and most of it works whether or not you ever touch his product. Enjoy!

All the best,
