70% of what your reps could sell… they don’t.

That’s the average ticket of reps who practiced with the full catalog and the company’s real objections.

The what

Your rep knows 5 products. Sells 3. Your catalog has 47. Average ticket is left on the table.

The how

They can greet and offer discounts. When the customer says “it’s way too expensive” or “I’ll think about it,” they freeze.

A synthetic customer that knows your catalog… and expects you to sell it well.

Real business RAG

Access to pricing, promotions, terms, exceptions, and the official script.

Dynamic emotions

Handle the objection and tension drops. Ignore it and it rises. Every call is different.

Voice-first

The rep dials a real number. It’s a normal call — the customer is 100% AI.

Actionable scoring

When it ends: a clear score and concrete recommendations to improve.

Here’s how it works.

Upload your catalog

PDFs, Excel, or your site. SynthCaller builds the Knowledge Base.

Pick a synthetic customer

“Benji, collector frustrated by the wrong product” — or generate one with AI.

The rep dials

They take the call on their phone and talk normally.

Instant feedback

Score + what improved and what to work on.

Not another role-play chatbot. Serious sales training.
