Why CoreValence exists
Built by one person who got a bad score — and decided people deserved a fairer, growth-first read from the colleagues who actually know them.
CoreValence started with a bad score. I went through a hiring process that leaned on a big-name personality assessment — and the result it spat out was so far from who I actually am that I barely recognized myself in it.
The unsettling part wasn't being misjudged. It was watching a single, confident-looking number get treated as the truth. Most mainstream psychometrics are tuned to population averages and neat trait labels, and along the way they flatten the exact nuance that decides whether a real person will thrive on a specific team. A career can quietly turn on that.
So I built the opposite: a way to see people through the eyes of the colleagues who actually work with them — grounded in peer-reviewed science, keeping people themselves instead of flattening them into a label, and never resorting to covert surveillance. It hands a person better evidence to grow from. It never decides for them.
CoreValence Peer Review exists for one question: what could this person learn that would drastically improve how they work with others? Not a ranking, not a verdict — the honest, corroborated view their team already holds, delivered in a way that helps them grow. The north star is simple and non-negotiable: growth, never judgment.

I'm the one and only person behind CoreValence. I've spent about fifteen years getting messy data and stubborn systems to behave — optimizing energy at EverCharge, automating biotech at Synthego, wiring together a tangle of other people's APIs at Natero, and running my own startup before that. Somewhere along the way I went all-in on building with AI agents, and this is where that led: designed, written, and run end-to-end by one person and a lot of Claude.
I care about this one because I've been on the wrong end of a lazy assessment. The goal isn't a tidier label — it's giving people a fairer read from the people around them, and a concrete way to grow from it.
