So many creators lose their unique soul to become something that the masses are willing to give a like to.

If you will follow a viral content playbook, please follow the one that will honor your story, your intention, and heart. You've got this. I love you.

How could we let this happen?

To quote Klaus Schwab, Founder of the World Economic Forum, on the impact of cyber security across our societies, economies, and geopolitical landscape:

"The COVID-19 crisis would be seen in this respect as a small disturbance in comparison to a major cyber attack."

"[...], which would bring to a complete halt to the power supply, transportation, hospital services, our society as a whole!"

[Ethan Glenny @iamethanglenny]

NOW HIRING: Engineers that want to work on something impactful.

Over the last year, we have been collaborating with multiple Fortune 500 CISOs, some of the world’s largest defense contractors, and other globally recognized organizations. All the while being backed by multiple Tier-1 VC firms here in Silicon Valley.

If you want to help protect our societies, economies, and geopolitical landscape against a rapidly growing set of global threat actors, we want to hear from you.

The world we know is no longer the same: Technology does not turn off when you close your laptop or turn off your phone.
