About Jousto

Energy, Automated — For Everyone

Founded in 2024 after 20 years in solar across the globe, Jousto exists to fix what lets Australian consumers down: sales-first retailers, rushed subcontractors, and systems that aren’t programmed for the customer’s best outcome.

We deliver smarter energy through open automation — the Jousto Energy Hub plus FREE Jousto Home Assistant Genius — and real partnerships with high-quality professionals near our customers.

Aarno the Jousto Viking — About Jousto

Why we started

The problem we saw

  • Solar retailers focus on sales, not outcomes.
  • Subcontractors optimise for speed, not optimisation.
  • Install companies are great at wiring, but many don’t program advanced tech for the customer’s advantage.

The Jousto approach

Consulting mindset, proprietary energy management, advanced programming know-how, and accredited design/efficiency expertise — delivered through an open platform that anyone can build on.

Plus, we forge true partnerships with quality professionals within ~40 km of our customers.
