What a Rewind email looks like

“We raised prices 3x in 18 months. Churn went down every single time. Nobody leaves a tool that saves them four hours a week over $20.”

TL;DR

Raising prices repeatedly reduced churn because the product's time savings outweighed the cost.

“Reminder that most 'AI infra' problems are still just caching problems wearing a costume. Measure before you rewrite anything.”

TL;DR

Profile and cache before rebuilding AI infrastructure — most bottlenecks are ordinary ones.

“New paper: models fine-tuned on 1k carefully curated examples beat ones trained on 50k scraped samples. Curation is the moat, thread below 🧵”

TL;DR

Small, well-curated datasets outperformed much larger scraped ones in fine-tuning benchmarks.

“Every seed deck I liked this quarter had the same trait: one metric on slide two, and the rest of the deck explaining why that metric moves.”

TL;DR

Strong seed decks lead with a single core metric and spend the rest explaining its drivers.
