He broke down how he launched with no audience, made around $10,000 on day one, kept his full-time job until the business was doing $80,000 a month , and eventually grew it to peaks of $200,000 a month with almost no overhead. We also talked about what makes productized services so powerful, why design and branding matter even more in the age of AI, and what kinds of agencies people can start right now using skills like copywriting , short form editing , thumbnail design , and AI-first development . Brett also shared his favorite AI tools, his best prompting advice, and why speed and simplicity are winning more than ever. https://x.com/BrettFromDJ Enjoy! --- Watch this on YouTube instead here…
