What is GuestButler?
GuestButler is a smart guest communication platform that automates up to 80% of repetitive guest questions using AI. Delivered through WhatsApp, the tool provides low-barrier, always-on support for travelers—boosting satisfaction while saving time for hosts and property managers. But it’s not just automation—it’s a digital “buddy” for guests that makes their stay more pleasant.
Why did you create GuestButler?
The idea came from my own experience. As someone renting out a holiday home, I noticed how time-consuming and repetitive guest communication could be. Even my local property manager was overwhelmed with the same recurring questions. So I asked myself: Can’t we do this smarter—with AI and WhatsApp?And that’s how GuestButler was born.
Do we really need another AI tool?
I get the question, but we’re not just jumping on the AI bandwagon—we’re using it to solve a real problem. Repetitive questions are mundane but important. AI allows you to respond instantly without sounding robotic. Our tool even adapts its tone to feel more like a person than a bot. When guests interact with George, they often don’t realize it’s AI—that’s the goal.
How did Achmea Impact Ventures help you build your startup?
Achmea Impact Ventures has all the resources, experience, and speed you just don’t have when working solo. Doing this from home would’ve taken months. Achmea made it possible in just a few weeks. It enabled GuestButler to move faster and smarter than traditional startup paths. Having researchers, developers and designers at your disposal is just a really helpful ecosystem.
