FROM THE TEAM

What's inside the box

It’s a real pleasure to share this video with you.

With the next generation of the Open Time Appliance Mini, we’ve focused on what truly matters: build quality, flexibility, security, and - above all - timing integrity.

There’s a lot of noise out there right now, but we stay in our lane, focused on what our customers actually need: reliable, secure timing distribution and verification.

Here’s our take—and frankly, it makes most alternatives look like toys.

- Unplug it? It keeps running on battery

- Jam it? It holds over with nanosecond-level accuracy

- Spoof it? It ignores the attack, thanks to signal authentication support

To the alarmists: pair this with one of our geodesic ring antennas and see how far typical spoofing or jamming setups really get. Good luck.

Timebeat. We’re serious about timing.

P.S. Shoutout to the entire crew who made this product come true: Muhammad Shah Rayyan Abhram Đoàn Nguyễn Hưng (Anakin) Peter Woodruff, CEng Jason Vo and Lam Nguyen It's amazing working with all of you. Thank you for being part of the journey.
