About
I’m Diederik, an industrial engineer with a slightly obsessive habit of optimising things. Yippie is the tool I always wished existed.
For years I worked the frontlines of customer service and planning: high-volume consumer support at a major online retailer, complex installation scheduling at a heat-pump installer, and critical software support for hospital departments at a healthcare scheduling vendor.
Different industries, same two extremes. Every single time:
Teams drowning in a shared Outlook or WhatsApp inbox. Nobody sure who was picking up which thread, things slipping through daily.
Over-engineered enterprise platforms: heavy, hyper-complex, and packed with features 90% of small businesses will never touch.
I knew it could be better. As an engineer, I knew I could build better. So I did. I built Yippie.
The frontlines
High-volume consumer support
Managing thousands of customer queries daily. The shared mailbox was always one message away from chaos.
Heat-pump installation planning
Complex scheduling across field teams and customers. Coordination that should have taken minutes took hours.
Hospital department scheduling software
Critical support where nothing could slip. Enterprise tools slowed everyone down instead of speeding things up.
The philosophy
One simple promise: take back your time. I strip away the admin clutter so you can focus on what matters: your customers.
Zero training required. Your team can get started in under five minutes. No onboarding sessions, no documentation rabbit holes.
No bloated enterprise pricing. Add modules à la carte, only when your team actually needs them.
Unlimited contacts on every plan. Unlock complexity only when your team needs it, not before.
No bloat. No missed threads. Just fast, minimalist support.
