Ruchi Sanghvi on Sweating the Details

TL;DR

Ruchi Sanghvi joined Dropbox after its acquisition of her startup Cove, intending to accelerate product releases like at Facebook, but realized Dropbox’s core value—reliability of user data—meant “move fast and break things” was destructive.

Key insights

• Faster release cycles (every day or two) that worked at Facebook for a social network were inappropriate for Dropbox, where losing user files (wedding photos, PhD theses) would be catastrophic.
• At Facebook, the only metric that mattered was adding users; at Dropbox, quality was paramount because even a 0.1% failure rate (e.g., the blue box stopping once per thousand clicks) would make users
• The last 10% of polish (sweating the details) takes roughly 50% of engineering time, which inherently slows development compared to Facebook’s ethos.
