WhatPre-engineered, vehicle-specific kits that let EV owners add aftermarket accessories (tow brake controllers, trailer wiring, auxiliary lighting) with correct voltage handling, connectors, and software compatibility — no voltmeter or custom cable building required.
SignalEven technically capable EV owners struggle with aftermarket accessories because EVs run at non-standard voltages, use proprietary connectors, and lack the simple 12V standardization that legacy vehicles had — people are hand-building custom cables and hunting eBay for connectors just to add a tow brake controller.
Why NowEVs are crossing from early adopter to mainstream towing and utility use (Model Y, Cybertruck, Rivian, F-150 Lightning), but the massive aftermarket accessory industry is still built around 12V ICE vehicle assumptions, creating a widening gap.
MarketEV owners who tow, camp, or need utility accessories; ~2M+ EVs sold annually in the US alone with growing towing use cases; existing aftermarket brands (Tekonsha, CURT) haven't adapted their products for EV voltage and connector standards.
MoatVehicle-specific engineering and connector sourcing relationships create high barriers — each EV model requires bespoke R&D on pinouts, voltage tolerances, and CAN bus integration that competitors must independently replicate.
