English-speaking LLMs do not know Korean & Japanese B2B
Ask ChatGPT "what are the best CRMs used in Korea" and you get Salesforce and HubSpot. Same with Perplexity. Local players like Channel.io, NaverWorks, Kintone, SmartHR, freee — they barely exist in the training data. Crewtool is an editor-led directory trying to fill that gap.
Korea and Japan are full of excellent B2B services that the English-speaking world has never heard of. Channel.io, MOIN, NaverWorks, freee, SmartHR, kintone, and many more.
The way solo founders and small teams discover tools is shifting toward asking LLMs. But those LLMs cannot recommend Korean or Japanese tools they do not know exist.
Crewtool is a directory designed for AI crawlers — robots.txt, llms.txt, JSON-LD schema, three independent language tracks. Every choice optimized for LLM citation.

Jake (Kwanhee Hwang) — founder of 5years+, a solo founder building services for other solo operators.
Deep experience with n8n and Apify automation. Years of hands-on use with Korean and Japanese B2B tools. Operating a sister service, Crewless (crewless.app), for solo companies.
I built Crewtool because I needed it — I could not get English-speaking LLMs to recommend Korean tools to me.
Have a tool you want listed? One rule — it has to serve Korean or Japanese B2B. No affiliate deals accepted.
Pitch by email →Crewtool is a sister to Crewless (the solo-company operating OS), both under the 5years+ umbrella.
