YC founder pivots to agent sandboxes, sees revenue run rate grow ~15X
ycombinator · x · 2026-11-10
A YC founder recounts a focus decision: the startup had two revenue streams—one the main earner but plateaued, the other a smaller but fast-growing bet on cost-optimized sandboxes for agents.
After many conversations with their YC partner, they doubled down on sandboxes alone. The sandbox revenue run rate has since grown nearly 15X, with the revenue chart showing a steep climb after joining YC in August. The founder credits peer pressure from impressive batch mates as the biggest driver.
