The Problem
Interview prep is broken.
Most people spend weeks preparing and still walk in underprepared. Not because they don't try — because the tools were never built for them.
Generic prep that misses the point
YouTube videos made for software engineers don't apply to sales or data roles. The frameworks are wrong and the advice doesn't transfer.
No honest feedback loop
You practice alone or with a friend who says 'sounds great' — and then bomb the real thing because no one actually challenged you.
You don't know what they're actually scoring
Sales and data interviews have specific evaluation criteria most candidates never see. STAR structure, quantified impact, role fit signals.
Zero reps before it counts
The average candidate's first live answer is in the real interview. That's a terrible first draft.
“The average candidate runs zero full mock interviews before their real one.”
— That's the gap we're closing.
The Platform

Instant Feedback
Scored across clarity, structure, specificity, and impact within seconds. Concrete suggestions on every answer, not just a generic score.

From the Founder
I spent 4 years at Google in enterprise SaaS sales. And even with that background, every new interview cycle stressed me out.
Not because I wasn't capable. But because structured, role-specific practice mattered — and there was no good tool for it.
I watched candidates who were less qualified land roles because they'd done more reps. They could articulate their impact. They knew the frameworks. They'd worked out the kinks before the real thing.
When I started interviewing candidates myself, I saw it from the other side: most people bombed not because they were bad at the job — but because they hadn't practiced enough.
So I built the tool I wish existed when I was prepping.
Your reps matter. Let's get them in.
“I'd rather you fail in practice a hundred times than fail in the real interview once.”
