Creator of CrystalDiskInfo/CrystalDiskMark, Microsoft MVP, Japanese open-source developer, Building sustainable OSS for 20+ years, Founder CrystalMark Inc.
Hi, I’m the creator of CrystalDiskInfo and CrystalDiskMark.
I’ve been building and maintaining open source software for over 20 years.
Along the way, I’ve learned that open-source can be sustainable — but only with the right structure.
Here I share:
• Lessons from long-term OSS development
• Sustainable business models for open source software
• Balancing community and commercial reality
If you're building software for the long run, welcome.
🎉 CrystalDiskInfo has reached 100 MILLION downloads!!
18 years after its first release in 2008, I never dreamed this day would come.
My heartfelt thanks to all users around the world and everyone who has contributed to its development.
I've shared the story of these 18 years of connections and gratitude!
