Sierro: Help Us Build Better Home Backup Power.

Hi there!

We’d like to invite you to participate in a short survey about Sierro, the world’s smallest home backup battery designed specifically for your living space.

Unlike bulky generators or portable batteries, Sierro is cat-sized and built to sit quietly in your home, protecting your essentials like fridge, CPAP, and WiFi during outages. Your feedback will help us fine-tune the final product ahead of launch.

This survey takes about 3–5 minutes to complete. All information collected will be kept strictly confidential.

Thank you for helping us bring reliable power to every home!

Best,
The Sierro Team
