Built in the courtroom. Designed for yours.

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’m a practicing trial attorney who has handled hundreds of matters across criminal and civil courts. I built TrialSim because the training that separates good advocates from great ones is not equally distributed — it depends on where you studied, who mentored you, and how many meaningful reps you received. TrialSim changes that math. PRESENCE is the framework I wish someone had handed me on day one.
