Jorge Del Castillo
Co-founder. Owns engineering, infrastructure, and the parts of the platform shops shouldn't have to think about — auth, data sync, the QuickBooks Desktop integration, uptime.
Jorge co-founded run a call. after watching too many residential HVAC shops bleed margin to software that was either built for plumbing, priced like ServiceTitan, or both. He owns the engineering side of the company.
Before run a call., Jorge led €6 million of operational engineering initiatives at Airbus — the kind of program where the system you're shipping touches a hundred technicians, a parts pipeline, and a customer waiting for an aircraft to fly. The mechanics of "the right tech, with the right parts, at the right address, in the right order" are the same whether you're servicing a wide-body or a 4-ton AC unit. So is the cost of getting it wrong.
After Airbus, Jorge co-founded an AI and automation firm focused on workflow optimization. The firm was acquired by Transputec, where Jorge now also serves as Head of Enterprise Automation. The product was a stack of automation systems for enterprise teams losing 30%+ of their week to admin overhead: ticket triage, parts routing, schedule reconciliation, data plumbing between systems that should have spoken to each other from day one. The same pattern shows up in residential HVAC at smaller scale — the dispatcher manually reconciling the board at 4pm, the bookkeeper retyping invoices into QuickBooks, the office manager chasing service-agreement renewals one PDF at a time.
At run a call. that engineering lens shapes the platform: a dispatch board that doesn't fall over when the shop hits 80 tickets in a day; QuickBooks Desktop sync that doesn't drift; mobile that works on the LTE you actually have on a job site, not the demo network; and reliability above what ServiceTitan publishes for itself (2.9 outages per month at 188-minute average resolution — the bar to clear, not the bar to meet). Jorge writes most of the technical long-form on this site — dispatch architecture, integration design, the engineering decisions behind the things shops feel.
