CraftJack is a Chicago-based service that helps homeowners find local home improvement contractors and vice versa. The company uses Twilio's API to distribute instant leads via SMS alerts, allowing contractors to respond faster, and voice broadcasting to automate calls confirming lead interest. This has improved closing rates and reduced costs compared to their previous provider. CraftJack's tech team built the apps using .NET and MySQL, finding customization with Twilio easier and cost-effective, as it charges lower per minute for outbound calls. The company is now counting on Twilio to support its aggressive growth plans, including adding features like click-to-call and call tracking.
