HYGH slashes dev time from months to days using ChatGPT Business

HYGH, a digital outdoor advertising company managing over 4,000 screens across Germany, is reporting a dramatic operational shift since adopting ChatGPT Business. Co-founder Antonius Link says the platform is saving an estimated 5.5 hours per employee each week. That’s not just a marginal gain—it’s a fundamental rewiring of how the company builds software and pitches clients. Where internal tool development once dragged on for one to two months, product managers and developers are now shipping about two usable minimum viable products every single week.

Link described the old process as clunky, riddled with endless meetings and dependencies that stalled even small internal tools. Now, a single person can take an idea, work with AI, and turn it into a functional product rapidly. The shift is tangible on the development side, where teams use Codex to bootstrap initial code and get prototypes running almost immediately. During one particularly productive week, the team launched five smaller internal software tools. On the planning side, the friction after brainstorming sessions has vanished. Teams record their conversations, and ChatGPT instantly generates a product requirements document. “The PRD is done while you’re still in the flow,” Link explained, eliminating the tedious task of manually reconfiguring notes after a meeting.

The efficiency gains extend directly to revenue-generating creative work. HYGH’s in-house agency is responsible for creating visual mock-ups to show advertisers how campaigns will look on their display network—a process that was previously a long, slow drag. Now, ChatGPT Business helps the creative team beat the blank page problem by drafting copy and generating visuals they then refine with design tools or Sora. The result is faster turnaround times for clients and a significantly higher volume of creative iterations to choose from. Link’s summary is blunt: “Revenue went up. Turnaround times went down. Output exploded.” The creative team has scaled its output without adding headcount, simply by automating the mundane parts of their workflow.

Beyond pure output, HYGH is embedding AI into its operational DNA. The move to the Business tier provided the necessary structure—shared workspaces, admin controls, and GDPR-compliant data handling—that individual employee usage lacked. To fuel this cultural shift, the company runs “workflow Wednesdays,” where staff demo automations and share best practices. Link notes a generational gap in usage, observing that younger employees don’t just query the tool like a search engine but “live with it,” making these knowledge-sharing sessions critical for sparking ideas across the organization. HYGH has already launched client-facing campaign preview tools using OpenAI’s APIs, allowing advertisers to snap a product photo and instantly see it displayed on a public screen. For Link, the trajectory is clear: ignoring AI means falling behind, and the only viable strategy is to involve it everywhere.
