A little over 10 years ago, @paulg published the essay "Do Things That Don't Scale." (paulgraham.com/ds.ht…) It was advice that spoke to the drastically different needs of an early startup versus the needs of a much larger, more established company.

They set out to fix something that frustrated them. Now, their tools help power over 30,000 applications. @Grg talks with co-founder @jeiting about the origins of @RevenueCat (YC S18) and what he's learned along the way: www.ycombinator.com/…

When @shuoshuooshuooo moved to the US as a teenager, she sold scooters at flea markets on weekends to help her mom. That experience inspired her to build her own company, @deel (YC W19) — which has grown to $500M ARR less than 5 years after its founding: www.forbes.com/sites…

YC S24's @ReactWise is building no-code software for chemical process optimization in pharma and biotech, reducing the experimental burden and cost by up to 95% when compared to exhaustive screening. Congrats on the launch, @alexanderpomb + @danielswigh! www.ycombinator.com/…
