Our Approach

“A complex system that works is invariably found to have evolved from a simple system that worked... A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over, beginning with a working simple system”

John Gall

We believe in simplicity, elegance and obviousness. For example, we believe in:

Maximum control: We don't rely on frameworks or third-party vendors, all our systems are built from the ground up by us. We have a deep understanding of what we run and the confidence to stand behind it.

Attention to detail: We never stop refining our design. We own every line of code and every part of the process and make constant improvements.

Automation: If it can be automated, it should be. We have 24hr, globally dispersed monitoring and backup systems, computers do the drudgery and busywork, people oversee them and make the decisions.

“The key to performance is elegance, not battalions of special cases”

McIlroy and Bentley
