On construction sites, communication is the lifeblood of progress, and it happens almost entirely on WhatsApp. Foremen, subcontractors, and site managers rely on group chats to share updates, confirm deliveries, and coordinate dozens of moving parts. It’s fast, familiar, and frictionless.
But this convenience comes with a hidden cost. Each WhatsApp group becomes a black box of critical data: progress photos, voice notes, and delivery confirmations get buried in endless scrolls of casual messages. Insights disappear, accountability blurs, and the result is often costly miscommunication.
That dynamic is now changing. Meta’s new WhatsApp Groups API, launched in October 2025, opens a secure, structured way to connect WhatsApp data to enterprise systems. Coral Messaging, one of Meta’s earliest partners, provides the infrastructure to make that possible, and Valoon, the German software company managing more than 1,000 construction projects globally, is putting it to work.
Together, Coral and Valoon are transforming the world’s most widely used messaging app into a true project management layer, within a market valued at roughly $3.1 trillion in 2024–2025, according to The Business Research Company. In such a vast sector, even incremental productivity gains can unlock billions in value.
From Group Chat Chaos to a Source of Truth
At the start of each project, Coral enables Valoon to create and manage dedicated WhatsApp groups for every trade, from concrete to electrical. These groups stay the same simple chats teams already use, but now every photo, document, and message automatically flows into Valoon’s structured project environment.
A foreman’s progress photo instantly lands in the right folder.
A supplier’s delivery confirmation is timestamped and logged.
A voice note from the site is transcribed, indexed, and tied to its relevant task.
This seamless bridge eliminates manual reporting and ensures that the day-to-day record of a construction site, once fragmented across phones, is now unified, searchable, and auditable.
Automation and AI at Work
Once WhatsApp becomes structured data, automation takes over.
AI-Generated Reports: Valoon’s AI analyzes daily chats and creates instant summaries of completed work, pending tasks, and issues, no manual note-taking required.
Automatic Photo Documentation: Every photo or video shared in chat becomes part of a visual timeline, creating effortless compliance and accountability.
Full Transparency: Every update is time-stamped and attributed, reducing disputes and keeping everyone on the same page.
What once required hours of administrative work now happens automatically in the background. Teams stay in WhatsApp while the system handles the structure.
The Bigger Picture
Construction is one of the world’s most collaborative yet least digitized industries. The WhatsApp Groups API represents a rare leap forward: it connects the tools people already use with the data discipline businesses need.
For Valoon, that means delivering on-time, on-budget projects through greater visibility.
For Coral, it means proving messaging infrastructure can become a foundation for industry-specific software.
And for the construction ecosystem, it signals the start of a smarter, future where WhatsApp groups aren’t just fast and easy for humans, but updates automatically feed into all the systems needed to deliver projects on time and on budget.
Keep your WhatsApp chats… & replace the chaos with clarity.
