Top SchoolJohn Mccalla is a veteran software leader and entrepreneur with 25+ years of hands-on experience building products and teams across startups and large enterprises. As Co-founder and CTO at Coral and former VP Engineering at Dialogue, he combines deep technical craft—spanning backend services, cloud orchestration, and front-end experiences—with a founder’s instinct for product-market fit. He has repeatedly shipped complex SaaS and media platforms (from Revit Live to Purple and MachBlue), often writing the initial service implementations himself and guiding their evolution into robust production systems. Comfortable in bilingual Francophone teams in Montreal, he blends technical leadership with commercial impact and a knack for rapid prototyping that turns experimental ideas into deployable products.
