Codex Lifts Fleet Sales 60%, Saves 75 Hours

Fleet management company Proaction rebuilt how it develops, runs, and sells its product using OpenAI's Codex, GPT-Live-1, and GPT-6 Astra. The shift lifted sales by 60% and freed up more than 75 hours of team time.

The trick is that the agents split the work: Codex speeds up coding, GPT-Live-1 handles live voice conversations with customers, and GPT-6 Astra supports selling and processing requests. Instead of separate teams for each task, the company runs one loop where routine work — from writing code to handling calls — passes through agents, while people focus on strategy and edge cases.

Check how many hours your managers spend weekly on repetitive calls, requests, and approvals — those are the first tasks ready for automation. 1Cifer follows a similar logic: sales and accounting each get their own agent inside one company workspace, processing requests, preparing summaries, and flagging where customers or money are slipping away.
