## About
We close the distance between people and infrastructure. Sigmoid builds software for the people who run infrastructure.
When a service runs well, its infrastructure is invisible.
Behind it is someone who takes the 3 a.m. page, trims the bill, and heads off the next outage.
Infrastructure is still far away. It's hard to learn, and harder to prove you're good at it.
Our work is closing the distance between people and infrastructure.
## Our work
- **[Paged](https://paged.team)**: From infrastructure design to incident response, hire and grow engineers on the cloud.
- Hiring: Verify operations and design skills that words can't prove through a practical test.
- Training: Solve everything from postmortem outages to architecture design to maximize team capability.
## Contact
If you've ever taken a 3 a.m. page, or have to hire someone you can hand that page to, or get the team you have ready for the next incident, we'd like to hear about it.
