The "Full Stack Builder" is a terrible idea (9 minute read)
AI makes drafts faster, so the extra capacity can go into more passes at stronger ideas. As building gets cheaper, the advantage will move towards teams that can turn abundant creation into work finely tuned to the customer. Teams that know the customer and the system can pull at its assumptions, correct the details, and tighten the story, so that by the time work reaches stakeholders, it carries the judgment of the team. The instruments are already in everyone's hands - the hard part is deciding what deserves to be heard.
Building a $2M ARR product after his $8M ARR product failed overnight (10 minute read)
Checkout X replaced Shopify's checkout and grew to $8 million ARR. Then Shopify locked down checkout and the business died overnight.

He stayed lean until $50,000 MRR, absorbed roughly $20,000 a month in losses for almost a year, then took revenue-based financing instead of venture money.

Meet your biggest competitor (👋 Claude) (7 minute read)
