About UPSCILL

Turning every rep into a top performer

We're building the AI sales performance platform we always wished we had — one where reps practice against hyper-realistic buyers, get coached on every call, and walk into real conversations already sharp.

Our mission

Great selling shouldn't be left to chance

Most sales teams still learn on live deals. New reps shadow a few calls, read a deck, and then practice on your real pipeline — losing winnable deals while they find their footing. Coaching is inconsistent, feedback is rare, and managers simply don't have the hours to be in every conversation.

We started UPSCILL because practice — the single biggest driver of performance in every other high-skill profession — was missing from sales. So we built it. Reps run unlimited voice roleplays against AI buyers modeled on your real customers, get instant coaching mapped to your methodology, and managers finally see who's deal-ready at a glance.

The result is simple: reps ramp faster, close more, and lose fewer deals to conversations they could have rehearsed.

What we believe

The principles behind the product

A few convictions shape every decision we make.

Outcomes over activity

We don't measure courses completed. We measure reps who close. Everything we build ties back to real revenue skill.

Reps come first

Sales is hard enough. We build practice that feels like a teammate, not a test — judgment-free and available 24/7.

Realism is the product

Practice only works when it feels real. We obsess over buyers who push back, stall, and object exactly like yours.

Trust by default

Your customer data powers the experience, so we treat security and privacy as table stakes, not features.
