SpaceX team shipped Grok Bot in 7 weeks, now shipping 4,000 PRs a month with AI coworkers

Lauren Tan and Roman Ugarte joined YC's Lightcone Podcast to explain how the Grok Bot core team went from first line of code to launch in seven weeks.
- Grok Bot spins up AI teammates with their own identities and logins that keep working in the background; the marketing team even gave a bot its own ad budget.
- Tan built an entire feature with her bot in a single Slack thread without ever opening Cursor.
- The team ships 4,000 PRs a month; topics include permissions for AI coworkers, bot-to-bot trust, code review practices, token-saving guardrails.
- Key takeaway: the hard part shifts from doing the work to deciding what to do and why — product judgment becomes the bottleneck.
