Mission & values

We're on a mission…

…to end the 'software tax' on high-volume mechanical firms by converting hidden transaction margins into proprietary engineering power.

10X Asset Valuation

Renting software adds zero value to your balance sheet. Building a proprietary engine creates a high-multiple asset that significantly increases your company’s exit price.

Subscription Overhead

Eliminate per-user fees and monthly seat costs forever. By redirecting hidden fees, you fund an elite engineering team without touching your current profit margins.

Automated Cost-Shifting

By automating a 1% Digital Infrastructure Fee into your labor or overhead, the software becomes a self-funding machine. You stop paying for tech; your transaction flow does.

Proprietary Moat

Off-the-shelf software forces you to work like everyone else. Custom code hardwires your unique trade secrets into a system that makes you faster and more profitable than the competition.

Team

Meet our founder

Finn Kaczmarowski

Founder and lead strategist

A veteran of the rapid-development ecosystem and a former Tech Lead, Finn Kaczmarowski founded Custom Trade Logic to solve the "tech-debt" crisis facing high-volume mechanical firms. Leveraging his background in scaling B2B partnerships and managing elite engineering pods, he identified a massive inefficiency: HVAC leaders were being forced to rent generic software while losing millions in hidden transaction margins. Today, Finn uses his expertise in systems architecture and fintech to help $10M+ firms reclaim their capital, replacing restrictive legacy templates with proprietary, custom-coded engines that turn transaction volume into a permanent company asset.
