Why Whisper exists
Built by one person who kept replaying conversations on the drive home — and decided the coach should show up while the conversation is still happening.
CoreValence started with a bad score. A hiring process once ran me through a big-name personality assessment, and the confident label it produced was so far from who I am that I barely recognized myself. I have distrusted machines that judge people ever since.
Whisper comes from noticing where that label problem does its worst damage: live, in the conversations that decide things. The negotiation, the interview, the hard talk. You prepare for an hour, and then in the moment you talk too much, ask too little, and miss the sentence that mattered. Every coach you could hire arrives afterwards.
The tempting fix is a machine that judges the other person in real time. That is the same lazy label, just faster, and the science says it doesn't work anyway. So I built a coach instead. It watches the conversation, keeps track of what was said, holds its tongue almost always, and hands you a few words when a better question or a well-placed silence is available. Its refusals are written into the product, and every design rule traces to a corpus of verified research digests — built end-to-end by one person and a lot of Claude, in the open.
Whisper exists for one question: what would you do differently if your best coach were in the room? Its whole output is a next move for you: check the claim, ask the question, let the silence work. The north stars are simple and non-negotiable: growth, never judgment; hypotheses, never verdicts. See how it works →

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 — and on the wrong end of my own hindsight, too many drives home. The goal is a coach that makes you better at the conversations you already have to have.
