Competing with giants: An inside look at how The Browser Company builds product | Josh Miller (CEO)

Josh Miller, CEO and co-founder of The Browser Company, shares how his team builds Arc—a web browser replacement with D5/D7 usage (active 5/7 days) in the low-to-mid 30s to low 40s percent retention, growing over 10% week-over-week for the past eight months. He details an operating philosophy reacting against metric obsession, focusing instead on evoking feelings like joy or speed, while using data to validate progress.

Feelings-first product development

The team optimizes for user emotions during creation—asking how to make people feel fast, organized, or surprised—rather than starting with graphs or metrics like Facebook's OBPS (one billion posts served) or sharing frequency. Metrics like D5/D7 track retention, engagement, and growth without gaming, serving as a honesty check after building. For features like Peek (hover-to-preview links without context-switching), discussions emphasize airiness and effortlessness in casual rooms, not formal PRDs listing feelings. This correlates with outcomes: surprise drives sharing. Caveat: pure metrics or pure feelings are flawed; balance depends on project, with SV skewed toward numbers.
