TRITAC did not appear out of nowhere. Matt trained for 25+ years under the senseis and coaches below. Two co-founders helped build the system before there was a logo. Four indirect influencers shaped specific areas: Sambo, Modern Arnis, Kali, BJJ. None of these people teach at TRITAC. All of them are inside it.
