Our vision

Our vision

The truth is, people are used to a crappy web. Slow, inefficient, generic experiences cause frustration for users and lost revenue opportunities for businesses. The problem is, they don't even know what they're missing. We're here to change that.

Access to real-time digital data (no matter how hard it is to achieve) improves user experiences. Better user experiences = more engaged customers who do more, spend more, share more, and keep coming back for more. But getting there isn't easy.

Our top-notch, no-nonsense engineers know that marketing B*** S*** is confusing. That's why we work in the open: open code, open solutions, clear data points – underpinned by a clear, innovative, Amazon Prime-style B2B subscription model for any business.

We're actively involved in standards and debates concerning the future of digital services through our participation with Movement for an Open Web.

We're making the digital world more rewarding for everyone.

  • Collaboration. We can't fix all your problems on our own. But we can provide the tools to reward the open-minded. Start with Pipeline API and see what it can do for you.
  • Performance. The web is slowing down due to an over-reliance on client-side JavaScript. The best way to fix this is to move functionality server-side. But server-side logic can seem hard.
  • Simplicity. We've spent three years creating an open source, server-side and client-side data pipeline to aggregate many micro services: Pipeline API is the result. And it's not just the data services we provide, but those by other companies like location services – and your own.
  • First party data. The web is becoming increasingly hostile to so-called “third party data services”. Moving all data and services to first party is the best way to future-proof your business. That's why our services on the cloud can be deployed on-premise, on your web server, and client side with framework-independent JavaScript routing data via your domain servers or to third parties. Did we mention it's easy to build your own?
  • Access. From free trial periods, to legal T&Cs written for the layman (no Latin legalese) and source code on GitHub, we're open for your business.

Data rewards the curious. All the more so when you have a helping hand.
