How SpaceXAI Built Grok Bot From Zero to Launch in Seven Weeks

Summary
Roman Ugarte on building Grok Bot: cloud-first execution and per-user cloud computers as the two early product bets, 'unshipping' internal reasoning/memory traces before public launch, building a separate app to avoid 'shipping your org chart,' and personally onboarding 200-300 users to catch bugs early.
Why this signal
A well-documented consumer-agent product-building case study; useful competitive/industry context though not directly a Thomas Engineering practice.
