ANTHROPIC BUILDS ITS OWN SOURCE CONTROL SYSTEM

Summary from the TLDR newsletter

Anthropic employs around 3,500 staff, but its coding output is closer to that of a company with 35,000 to 70,000 staff. Big tech companies like Google and Meta moved off Git a long time ago because it did not scale for them. Both built their own custom solutions, just like Anthropic did with Scion.
