Code less, query more: A co-founder's 30-day dive into Claude Code sub-agents
Kenta Yamamoto, Chief Innovation Officer and Co-Founder at primeNumber, has an engineering background but no time to write code as a business lead. He went all in on Claude Code sub-agents for 30 days and found the real unlock wasn't the agent, it was the data layer feeding it. He shares an Orchestrator + Sub-agent pattern that scales beyond coding, plus an honest log of wins and misses.
