Hala Systems partnered with Rippleworks to build an acoustic detection device that alerts civilians of audible threats

Hala Systems is a social enterprise working to transform the nature of protection and accountability in the world’s toughest places by democratizing advanced defense, sensing, and artificial intelligence technology. Hala is currently saving lives, reducing trauma, and improving resilience for millions of people.

Hala’s top priority was enhancing their Sentry Warning System to better generate credible, real-time, situational awareness of threats in conflict zones. Hala partnered with Rippleworks to build a low-cost acoustic detection device capable of alerting civilians of incoming missiles, bombs, and gunshots.

We saved a tremendous amount of time working with an experienced expert who could help us avoid pitfalls and put us on the right path.

This helped to empower our technical team to make leaps ahead of where we would be otherwise.

—Hala Systems co-founder and COO Dave Levin
