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.
