Stable
Stable is an AI-powered virtual mailbox and business address service that turns the office mailroom into software. Founded in 2019 and part of Y Combinator's Winter 2020 batch, the company gives distributed and remote-first businesses a permanent U.S. address, scans and digitizes incoming physical mail, and automates downstream workflows like check deposits, registered agent filings, and routing. More than 15,000 businesses - from startups to enterprises like Gusto, Brex, and DoorDash - use Stable to handle mail from anywhere.
Sarah Ahmad
Sarah Ahmad is the CEO and co-founder of Stable, an AI-powered virtual address and mailbox platform that lets distributed companies run a real business from anywhere. Launched out of Y Combinator in early 2020, just as the pandemic emptied offices, Stable digitizes physical mail, handles registered-agent duties, and automates check deposits for more than 15,000 businesses, from day-one startups to S&P 500 names like DoorDash and Realty Income. A Northwestern engineer who sold custom MySpace layouts at age 10 and folded her first startup before founding her second, Ahmad leads with a blunt creed: listen obsessively, decide with confidence.
