Built in the courtroom. Designed for yours.

TrialSim was built by a former prosecutor with 50+ bench trials who knew what real advocacy training should feel like. Now anyone can access it.

Why TrialSim exists

The reps that make great trial attorneys — the drilling, the pressure, the immediate feedback — have always required a clinic seat, a mentor, or a courtroom. Most advocates never get enough of them. TrialSim exists to change that.

Meet the founder

Founder chilling in Brooklyn, NY
I’ve tried over 50 cases as an Assistant District Attorney and now litigate in civil courts. I built TrialSim because the training that separates good advocates from great ones isn’t equally distributed — it depends on where you went to school, who mentored you, and how many reps you got. I wanted to change the math on that. PRESENCE isn’t just a scoring system. It’s what I wish someone had handed me on day one.
