Hi, I'm Raehyeon (Neo) Jeong — an Entrepreneurial Engineer.
I believe a startup is the greatest force humanity has, and the most beautiful art a human can make.
Silicon Valley's startups change the world, I think, because more failure piles up there than in any other city.
Pioneers who fail and try again — I love a startup scene full of people like that.
I have no intention of ever leaving the side of people working to create new value, and every day among them is a joy.
I carry that spirit of challenge into my own life. As much as I love people and philosophy, I believe Korean society should chase sustainability far harder than it does.
We should be taking far more action for future generations than we are now.
At Potentivo Lab, I build and operate Parentlyze's full product stack: the iOS and Android apps, web platform, admin back office, AI engine, and internal operations systems. Parentlyze helps parents turn family conversations into structured insights, personalized reports, and practical coaching missions. parentlyze.com
And for the past two years, every four days, I've helped run Private Meetup so all kinds of people can dream up bigger value together and make it real — more than 200 meetups so far. meetuplab.com
I studied Electrical & Electronic Engineering at Yonsei University and Computer Science at 42 Seoul. I love computers and software, so I keep building tools for myself and the teams I work with, strapping more on like cyberware.
I'm doing harness engineering on my own life, borrowing the power of software engineering to pull it off.
Connecting with new people is always a joy. Reach out anytime :)
What I build
Beyond products, I keep building tools my team and I actually use. A few of the lanes:
- ▸Public products — Parentlyze · Fjord Edu · WorldCloneLab · Recallink and other services with real users
- ▸CRMs and outreach systems for teams and myself — pulling scattered data into one funnel to manage relationships
- ▸Internal marketing & content automation tools — in-house pipelines that ship cardnews, short-form, and reports fast
- ▸An openclaw-based agent fleet and data-collection pipelines — many machines collecting, enriching, and verifying 24/7
- ▸Plus many private and experimental builds — new prototypes shipped and measured regularly
