As answered by people managing Codewars and ContractorHUB.app.
ContractorHUB.app's answer:
ContractorHUB was built by someone who’s lived the reality of growing a home service business
The founder has spent 20+ years scaling home service businesses across roofing, HVAC, remodeling, landscaping, and other trades—first as a marketing consultant, then as an operator focused on results, systems, and team performance. He helped grow a Tennessee roofing company from $6M to $19M in three years by building the operational structure to support rapid growth, and as an experienced Laravel developer, he turns real-world challenges into practical, easy-to-use software.
