“Absolutely exceptional work. Our 350kW charger was overheating during stress testing and we were 3 weeks from production. They ran CFD simulations, redesigned the cold plate, and delivered production-ready CAD files in 5 days. Junction temps dropped 42°C. This level of expertise saved our entire product launch.”

Our Methodology

Debatched Engineering

We break every project into hour-by-hour activities, eliminating dead time and delivering results at speeds impossible with traditional consulting.

Zero Dead Time

No waiting for meetings, approvals, or handoffs. Every hour is productive work on your project.

Hour-by-Hour Tracking

Every activity is time-boxed. You know exactly what's happening and when.

Rapid Iterations

Quick feedback loops mean faster convergence to optimal solutions.

Engineering expertise you can trust

We're a team of power electronics, thermal, and mechanical engineers who've spent years solving complex design challenges—from thermal management and EMI compliance to rugged enclosure design for demanding applications like 350kW EV chargers and MW-scale grid storage systems.

We started Ohmframe because we saw too many hardware startups struggling with thermal, EMI, and mechanical issues late in development. Our mission is to help you get these critical design elements right from the start, so you can focus on what makes your product unique.

Every project gets hands-on attention from senior engineers. No junior handoffs. No black-box simulations. Just clear, actionable engineering that moves your product forward.
