Clean PHP for real businesses
PHP AIR is run by Ian Croasdell. It builds clean, fast PHP websites, booking and enquiry systems, automation and integrations for small businesses, and business-trained AI chat assistants that answer from the information a business has approved, with clear limits and a hand-over to a person when needed.
The approach is simple: understand the business first, then build the system around it. Lightweight PHP keeps the system owned by the business, with affordable hosting and maintenance that stays understandable.
