Built by salespeople who hated wasting their own time
and everyone else's
Salesprep started because practising in front of colleagues felt awkward, took too long to set up, and rarely happened. We wanted something you could do alone, at your own pace, and still improve faster than with any sparring partner.
Why
Friction was the problem, not quality
Roleplaying with colleagues takes two calendars, a willing sparring partner, and someone who can actually play an uncomfortable counterpart. In practice it rarely happens, so salespeople train on live leads instead, which gets expensive in both wasted time and lost deals.
Salesprep replaces the second person with a voice AI that answers like someone on the phone. Practise at your own pace, on your own schedule, and improve without depending on anyone else. Salesprep is built and run by Byron Calles AB, a Stockholm-based company founded in 2025, and it's Swedish-first. Write to us at [email protected].
Principles
How we think about the product
The scoring has to feel fair
Every score comes with a concrete comment that points at what worked and what to improve. No vague criticism.
Routine beats intensity
Better to train 15 minutes a day than two hours once a month. From the daily session to the improvement report, the product is built around repeated reps.
The human doesn't come second
The AI takes over the volume, but the sales coach becomes more important, not less. The improvement report is built to be read by a coach.
