About Locke

Conversation is the oldest interface.

Locke is an applied lab and product company. We build brains that answer everyone the way your best person would, and we study what makes a conversation feel personal.

“As a doctor, I always wanted more time for people. I’m curious what happens when we can really listen, and help far more people, without anyone feeling rushed.”

What we’re testing about conversation.

Led by Dr. Muddy Bhatt. Working ideas, not measured results.

Knowing when to stop matters as much as knowing the answer.

Why it matters The hard questions reach your team, not a guess.

Small delays and interruptions break a conversation faster than anything else.

Why it matters Fix them, and people stay to ask the next question.

The uncanny valley is shorter than people expect.

Why it matters Past it, a conversation can feel personal.

People want to ask, not read.

Why it matters Answer them on your website, and they decide the next step with you.

Why we do this.

People want an answer, not a search through your pages. A personal, face-to-face conversation has always been the best there is.

We want everyone to get that feeling, at a scale no team could manage alone. Our research finds where conversation helps most, and what it takes to make it work.

Tell us who needs to reach you, and what it should answer first.

Four fields to start. A person reads it, and you hear back within two business days.
